Rural Low-Voltage Overhead Lines: The power demand in rural areas is relatively scattered, and overhead lines are mostly used for power transmission. The 5-core design of this cable can meet the power supply of multiple households or small public facilities in rural areas. The 2.5mm² cross-section can carry the daily power load in rural areas, such as lighting and small household appliances. During overhead installation, its armored structure can resist the impact of wind and rain, collision by small animals, etc. in the rural outdoor environment. The flame-retardant performance of the XLPE insulation layer also reduces the risk of safety accidents caused by accidental fire of the line.

Overhead Power Distribution Inside Factory Areas: Inside the factory area, it is necessary to transmit power from the main distribution room to various production workshops, office buildings and other areas, and overhead power distribution is one of the common methods. This cable can be used as an overhead power distribution line inside the factory area. The 5-core design can adapt to the power needs of different equipment and areas in the factory area and realize multi-circuit power transmission. The armored structure can protect the cable from possible mechanical collisions, accidental scratches during equipment handling, etc. in the factory area, ensuring the stability of power supply in the factory area.

Power Supply for Small Outdoor Public Facilities: Small outdoor public facilities such as lighting equipment in small outdoor parking lots and small outdoor pumping stations usually need to be powered by overhead lines. The specifications and performance of this cable are exactly suitable for such scenarios. The 2.5mm² cross-section can meet the power demand of the equipment, and the armored and flame-retardant characteristics can adapt to outdoor environmental conditions, ensuring the normal power consumption of public facilities.

Material

Style

Conductor Preparation: According to the selected Conductor Material (copper or aluminum), screen and purify the raw materials to remove impurities. Melt the pure raw materials to make metal rods, and then draw the metal rods into metal wires of the required diameter through a wire drawing process. Then, strand multiple metal wires together to form a conductor. During the stranding process, ensure the roundness and tightness of the conductor to ensure the stability of conductivity.

Insulation Layer Extrusion: Add XLPE materials into the extruder and heat to melt them. Under the pressure of the extruder, the molten XLPE material is evenly extruded and coated on the outside of the conductor through a mold to form an insulation layer. During the extrusion process, it is necessary to accurately control parameters such as temperature and speed to ensure that the insulation layer has a uniform thickness, a smooth surface, and is closely combined with the conductor without defects such as bubbles and impurities, so as to ensure insulation performance and flame-retardant performance. After extrusion, cool and solidify the Insulated Core.

Cabling: Strand 5 cores covered with insulation layers in a certain stranding way. During stranding, ensure that the cores are arranged evenly and the tension is consistent to ensure the roundness and structural stability of the cable. Filling materials may be added during the cabling process to make the cable structure more compact.

Armoring Treatment: Perform armoring treatment on the outside of the cabled cable. Wrap the steel tape or steel wire on the cable at a certain angle and tension through an armoring machine to form an armored layer. During the wrapping process, ensure that the armored layer is tight and flat without looseness, wrinkles, etc., so as to give full play to the protective effect.

Sheath Extrusion (if any): If a sheath is designed, after the armoring treatment is completed, add the sheath material into the extruder, heat and melt it, and then extrude and coat it on the outside of the armored layer to form a sheath. During extrusion, control the process parameters to ensure that the sheath has a uniform thickness, a smooth surface, and is closely combined with the armored layer.

Inspection and Testing: After production, conduct various inspection and testing on the cable. Including appearance inspection to check whether the cable surface is damaged and whether the armored layer is flat; dimension measurement to detect whether the outer diameter, insulation layer thickness, etc. meet the standards; electrical performance testing, such as insulation resistance testing and withstand voltage testing; flame-retardant performance testing to verify its flame-retardant effect under high temperature or fire conditions; mechanical performance testing to check the impact resistance, tensile resistance and other properties of the armored layer. Only cables that pass all tests can leave the factory.

Packaging Materials: This cable is usually packaged with cable reels, which are mostly made of wood or metal. Wooden cable reels have low cost and are suitable for short-distance transportation and general storage; metal cable reels have stronger load-bearing capacity and better durability, and are suitable for long-distance transportation. On the cable reel, the outer layer of the cable will be wrapped with a layer of plastic film, which plays a role in moisture-proof and dust-proof, avoiding pollution and damage to the cable during storage and transportation.

Packaging Method: Wind the cable neatly on the cable reel. During winding, ensure that the cable is arranged closely without distortion or overlap to prevent damage caused by mutual extrusion of the cable during transportation. After winding, wrap the entire cable tightly with a plastic film, and then fix the cable on the cable reel with steel strips or ropes to prevent the cable from loosening and sliding off. The cable reel will be marked with the cable's model, specification, length, manufacturer, production date and other information for easy identification and traceability.

Transportation Methods: Choose appropriate transportation methods according to the transportation distance and quantity. Road transportation is generally used for short-distance transportation, using trucks, which has high flexibility and can directly deliver the cable to the destination. For long-distance transportation, railway transportation can be chosen. Railway transportation has good stability, is suitable for transporting large quantities of cables, and can reduce the impact of bumps during transportation on the cable.

Delivery Process

Delivery Time: For cables in stock, packaging and delivery will be arranged within 1-2 working days after order confirmation. If it is a customized product, production will be arranged according to the production cycle (usually 5-10 working days), and delivery will be made within 1 working day after production is completed. If delivery is delayed due to special circumstances, customer service personnel will communicate and explain with the customer in advance.

Sample Provision: If customers need to know the quality, performance, etc. of the cable before purchasing, they can apply to the company for samples. The company will provide corresponding samples according to the customer's requirements, and the length of the sample is generally 1-2 meters to meet the customer's testing and trial needs.

Sample Cost: Samples are provided free of charge, but the transportation cost of the samples is borne by the customer. If the customer places a bulk order after receiving the sample and the order amount reaches the agreed standard, the company will refund the transportation cost of the sample.
