I. Information Related to the Product Itself
(I) Specification Parameters
The specification parameters of Cable Exvb (Eca)
0.6/1kv Cable are rich and accurate, providing a solid foundation for its stable application in different low-voltage power distribution scenarios.
The rated voltage of this cable is clearly 0.6/1kV, where 0.6kV is the phase voltage and 1kV is the line voltage, which is fully in line with the general standards of low-voltage power distribution systems. This voltage level enables it to perfectly match common low-voltage power distribution equipment, such as low-voltage circuit breakers and distribution boxes, ensuring that there will be no faults due to voltage mismatch during power transmission and fundamentally ensuring the stability of power transmission.
In terms of conductor specifications, the cable has a variety of options. In the 3G2.5mm² specification, "3G" represents 3 cores, with a cross-sectional area of 2.5mm² for a
Single Core, and its continuous current-carrying capacity is about 16A; the 4×10mm² specification has
4 Cores of 10mm², with a continuous current-carrying capacity of up to 40A; the 4×16mm² specification has
4 Cores, each with a cross-sectional area of 16mm², and the continuous current-carrying capacity is about 50A; the continuous current-carrying capacity of the 4×25mm² specification can reach about 65A. The continuous current-carrying capacity of 5g6mm² ("5g" means
5 Cores) is about 25A; 5g10mm² is about 40A; 5g16mm² is about 50A; the continuous current-carrying capacity of the 5×25mm² specification is around 65A. The differences in current-carrying capacity of these different specifications allow it to accurately match the power transmission needs of different powers.
In addition, the insulation thickness of the cable is adjusted according to different specifications. The insulation thickness of small specifications such as 3G2.5mm² is about 0.8mm, and that of large specifications such as 5×25mm² is about 1.2mm to ensure good insulation performance. Its minimum bending radius is 8-10 times the outer diameter of the cable, which can adapt to laying environments with limited space such as homes and small commercial places. The operating temperature range is between -20℃ and 70℃, and it can work stably under common climate and environmental conditions.
(II) Characteristic Uses
Cable Exvb (Eca) 0.6/
1kv Cable, with its various specifications and stable performance, has targeted applications in multiple low-voltage power distribution scenarios and can meet the power transmission needs of different scenarios.
In the field of home power distribution, this cable performs well. The 3G2.5mm² specification cable is an ideal choice for home lighting and ordinary socket lines. It can connect the home main distribution box to lighting fixtures, TV sockets, air-conditioning sockets (for low-power air conditioners) in each room, and its current-carrying capacity can meet the power demand of these devices. The 4×10mm² specification cable can be used for the power supply lines of high-power electrical appliances in homes, such as electric water heaters and high-power air conditioners, ensuring stable power supply during the use of these appliances.
This cable can also be used in the power distribution lines of small commercial places, such as convenience stores and small supermarkets. The total power consumption of cash registers, refrigerators, lighting systems, etc. in convenience stores is relatively moderate. The 4×16mm² specification cable can be used as the main power distribution line of the store, connecting the store's main distribution box to the branch lines in each power consumption area. For branch lines in the store, such as power supply for shelf lighting and small refrigerators, the 3G2.5mm² or 4×10mm² specification cable can meet the demand.
In the power supply scenarios of small industrial equipment, this cable can also play a role. For the power supply lines of some small machine tools and small processing equipment, the 5×25mm² specification cable can be selected, and its large current-carrying capacity can ensure the normal operation of the equipment. For the control lines around the equipment, which connect the equipment control panel to the power supply, the 5g6mm² or 5g10mm² specification cable is more suitable, which can stably transmit the power required for control signals.
In addition to the above scenarios, this cable also has application space in the power distribution system of office places. The 4×10mm² or 4×16mm² specification cable can meet the demand for the power supply lines of office equipment such as computers, printers, and air conditioners in the office, ensuring the normal use of office equipment.
(III) Material and Style
The material selection and style design of Cable Exvb (Eca) 0.6/1kV cable are fully combined with its performance requirements and application scenarios, providing a guarantee for the safe operation and convenient installation of the cable.
The conductor is made of high-purity copper with a purity of more than 99.9%. High-purity copper has excellent conductivity, which can reduce energy loss during power transmission and ensure power transmission efficiency. The conductor is made of multiple strands of fine
Copper Wires stranded together. This structure enhances the
Flexibility of the conductor, enabling it to better adapt to bending and turning in environments with complex laying paths such as homes and small commercial places, reducing the risk of breakage. At the same time, the surface of the
Copper Conductor is tinned to form a protective film, which can prevent the conductor from being oxidized and corroded during long-term use and storage, extending its service life.
The insulation layer is made of PVC (polyvinyl chloride) material. The
PVC Insulation layer has good insulation performance, which can effectively isolate the current conduction between cores and between cores and the external environment, ensuring the safety of power transmission. It also has certain temperature resistance and corrosion resistance. It can maintain stable performance in the working temperature range of -20℃ to 70℃ and is not easily corroded by common acids and alkalis, adapting to the environment of homes and commercial places.
The outer sheath of the cable is also made of PVC material. The
PVC Sheath is tough and has good mechanical strength, which can resist slight external extrusion, collision and other mechanical forces, protecting the internal insulation layer and conductor. The surface of the sheath is smooth, which is convenient for the cable to pass through pipes, trunking, etc. during laying, reducing laying resistance. At the same time, the PVC sheath has certain flame retardancy, which can delay combustion when exposed to open fire, adding a guarantee for safe electricity use.
In terms of style, the cable has a
Multi-Core cabling structure and is round as a whole. The multi-core structure can meet different power distribution needs. For example, 3-core, 4-core, and 5-core correspond to different power distribution systems respectively. The round structure enables the cable to bear uniform force during laying, which is convenient for winding and storage, and can better match with laying facilities such as pipes and trunking. The outer surface of the cable is printed with clear marks, including model, specification, rated voltage, manufacturer, etc., which is convenient for identification and traceability.
(IV) Production Process
The production process of Cable Exvb (Eca) 0.6/1kV cable is rigorous and standardized. Each link from raw material processing to finished product inspection has strict quality control to ensure that the product quality meets relevant standards.
Conductor preparation is the first step of production. High-purity copper rods are drawn into fine copper wires of the required diameter through a wire drawing process. During the wire drawing process, the wire drawing speed and die precision are strictly controlled to ensure that the diameter of the copper wires is uniform and the surface is smooth. Then, according to the requirements of different specifications, a certain number of fine copper wires are stranded. During stranding, stable tension and appropriate pitch are maintained to make the conductor structure compact and round and enhance flexibility. The
Stranded Conductor is tinned. The conductor is put into tin liquid to make the surface evenly covered with a layer of tin, and then cooled and shaped after completion.
The insulation extrusion link is crucial. First, the PVC insulation particles are dried to remove moisture from the particles to avoid bubbles in the insulation layer. The dried PVC particles are sent to the extruder, melted at a set temperature (usually 150-170℃), and evenly coated on the outside of the conductor through a special extrusion die to form an insulation layer. During the extrusion process, the temperature, pressure and extrusion speed are monitored in real-time to ensure that the insulation layer has a uniform thickness, high concentricity with the conductor, and a smooth surface without defects.
The cabling process is to strand multiple
Insulated Conductors together in a certain stranding way. According to the number of cores (3-core, 4-core, 5-core), corresponding stranding dies are used. During stranding, stable tension is maintained to make the cabled cable have a compact and round structure. For specifications that need to be filled, filling materials will be added during the stranding process to make the cable shape more round.
Sheath extrusion is the last key process. The PVC sheath particles are dried and sent to the extruder. After melting, they are evenly coated on the outside of the cabled conductor through an extrusion die to form a sheath. The extrusion process parameters are controlled to ensure that the sheath has a uniform thickness, is closely combined with the internal structure, and has a smooth surface. The sheath can protect the internal structure from the external environment.
In the finished product inspection link, a comprehensive test is carried out on the conductivity, insulation performance, sheath mechanical performance, etc. of the cable. The conductivity of the conductor is checked through a DC resistance test, the insulation effect of the insulation layer is verified through insulation resistance and voltage withstand tests, and the mechanical strength of the sheath is inspected through a tensile test. Only cables with all indicators qualified can leave the factory.
II. General Product Information
(I) Packaging
The packaging design of Cable Exvb (Eca) 0.6/1kV cable focuses on protecting the integrity of the cable during storage, transportation and handling, and at the same time takes into account the convenience of packaging and the clarity of identification.
For small-specification and short-length cables (such as 3G2.5mm² with a length of less than 100 meters), plastic reels are used for packaging. The plastic reel is light and easy to carry and store. The cable is neatly wound on the reel, and appropriate tension is maintained during winding to avoid loose and
Twisted Cables. The reel is covered with a plastic packaging bag to play a role in moisture-proof and dust-proof. The basic information of the product, such as model, specification, length, etc., is printed on the packaging bag.
Large-specification and long-length cables (such as 5×25mm² with a length of more than 100 meters) are packaged with wooden cable reels. The diameter of the wooden cable reel is determined according to the length of the cable, generally 0.8-1.5 meters, which can stably bear the weight of the cable. The cable is wound on the cable reel in a tight arrangement without overlapping or twisting. Baffles are installed on both sides of the cable reel to prevent the cable from slipping during transportation and storage. The outside of the cable reel is wrapped with a layer of plastic film. For cables that need long-distance transportation, a waterproof canvas is covered outside the plastic film to enhance moisture-proof and sun-proof performance.
Both plastic reels and wooden cable reels are pasted with detailed labels. The labels are marked with product name, model, specification, length, production batch number, production date, rated voltage, manufacturer name and contact information, etc. The labels are made of wear-resistant and waterproof materials to ensure that the information is clearly identifiable during transportation and storage. At the same time, warning signs such as "Handle with Care" and "Moisture-proof" are also marked on the labels.
For sample cables, small sealed bags are used for packaging. Each bag contains 1-2 meters of samples. The specifications, production batch numbers and other information of the samples are marked on the sealed bags, and sample descriptions are attached.
(II) Transportation
The transportation of Cable Exvb (Eca) 0.6/1kV cable must follow certain specifications to ensure that the cable is not damaged during transportation and its performance is stable.
The transportation method is selected according to the transportation distance, cable specifications and quantity. For short-distance transportation with a small quantity, small trucks or logistics express can be used. The packaged cables (packaged with plastic reels) are put into cartons, and buffer materials are filled in the cartons to prevent the cables from shaking and colliding during transportation. For long-distance transportation with a large quantity, road freight is used. The cables packaged with wooden cable reels are fixed in the truck compartment, and ropes or fastening belts are used to firmly connect the cable reels to the compartment to prevent sliding.
When loading and unloading cables, small-specification cables can be carried manually, but attention should be paid to handling them with care to avoid falling; large-specification cables need to use forklifts or small hoisting equipment, and collision and extrusion of cable reels should be avoided during loading and unloading.
During transportation, attention should be paid to: Cables should avoid open-air transportation. If it is unavoidable, they should be covered with waterproof canvas to prevent exposure to the sun and rain; keep away from fire sources and heat sources. Transport vehicles are not allowed to approach open fire areas; drivers should drive steadily during transportation to avoid sudden braking and sharp turns and reduce cable shaking; regularly check whether the cable packaging is intact, and deal with it in time if it is damaged.
After arriving at the destination, the receiver must check the packaging and appearance of the cable together with the transporter, and sign for it only after confirming that there is no damage. If there is any damage, take photos and record it in time and communicate with the shipper.
