Comprehensive Product Description of XLPE LSZH Lsoh-Fr 3f+1t Flexible Cable
I. Analysis of Core Parameters and Performance of the Product
(I) Basic Specification Parameters
This XLPE LSZH Lsoh-Fr 3f+1t flexible cable mainly includes two core specifications, namely Rz1-K type 3*185+95mm² and 95 Sq mm 4-core
Copper Conductor Cable. Both specifications of cables have a rated voltage of 0.6/1kv, which can meet the voltage requirements in conventional power transmission scenarios.
In terms of conductor specifications, the 3*185+95mm² cable consists of 3 main cores with a cross-sectional area of 185mm² and 1 neutral core with a cross-sectional area of 95mm². This structural design not only ensures the capacity of main power transmission but also realizes circuit balance and safety protection through the neutral core. The 95 Sq mm 4-
Core Cable adopts
4 Cores with a cross-sectional area of 95mm², and its overall symmetrical structure enables more balanced power distribution, making it suitable for scenarios with clear requirements for three-phase four-wire power supply.
There are certain differences in the overall diameter and weight between the two specifications of cables. Due to the larger core specification, the 3*185+95mm² cable has a diameter of approximately XXmm and a weight of about XXkg per meter; the 95 Sq mm 4-core cable has a diameter of approximately XXmm and a weight of about XXkg per meter. However, both specifications of cables maintain good
Flexibility and can meet the requirements of bending and laying despite the differences in specifications.
(II) Advantages of Material Performance
Conductor Material
The conductor is made of high-purity copper with a purity of over 99.99%. The high-purity copper material fundamentally ensures the excellent conductivity of the conductor. Compared with ordinary
Copper Conductors, its conductivity is increased by about 5%-8%, which can effectively reduce power transmission loss.
To enhance the flexibility of the cable, the conductor adopts a multi-strand stranded structure. This structure allows each strand of the conductor to coordinate with each other during bending, reducing internal stress. It not only facilitates bending operations in narrow spaces but also reduces the risk of damage due to excessive bending during laying. At the same time, the multi-strand stranded structure also improves the fatigue resistance of the conductor, extending the service life of the cable.
Insulation Layer Material
The insulation layer of the cable is made of cross-linked polyethylene (XLPE) material. XLPE has excellent insulation performance with extremely high insulation resistance, which can effectively prevent current leakage and ensure the stability of power transmission. In addition, the XLPE insulation layer has a wide temperature resistance range (-40℃ to 90℃) and can work normally in such an environment. In low-temperature environments, XLPE will not become brittle and crack due to freezing; in high-temperature environments, it can also maintain good insulation performance without accelerated insulation aging.
The XLPE insulation layer also has excellent resistance to water vapor and chemical erosion. In humid environments, such as underground laying or places close to water sources, it can effectively prevent water vapor from penetrating into the conductor, avoiding the impact of moisture on insulation performance. At the same time, it can also resist the erosion of common chemical substances in industrial environments, such as acid and alkali solutions, ensuring the normal operation of the cable.
Sheath Material
The sheath of the cable is made of low smoke zero halogen (LSZH/Lsoh-Fr) material, which has the characteristics of low smoke and halogen-free when burned. In case of fire and other accidents, it will not release toxic and harmful gases, and produce little smoke, which greatly reduces the risk of poisoning and suffocation of personnel and buys valuable time for personnel evacuation and rescue work.
Outside the LSZH sheath, there is a black PVC outer layer. The black PVC material has excellent wear resistance and corrosion resistance. During the laying and use of the cable, it can resist mechanical damage such as external friction and collision, and at the same time, it can resist the erosion of corrosive substances in the soil and pollutants in the air on the sheath, extending the service life of the cable.
(III) Characteristic Performance
Flexibility Advantage
Benefiting from the multi-strand stranded structure of the conductor and the overall design, the cable has good flexibility. This flexibility enables the cable to easily adapt to various complex wiring environments during laying. Whether it is bending, turning, or pipe threading, it can be completed smoothly. For example, in the narrow space inside a building, the cable can be flexibly arranged according to actual needs without being difficult to construct due to excessive rigidity.
Safety Performance
In addition to the safety characteristics of the LSZH sheath when burned, the overall structure of the cable also fully considers safety. The high insulation resistance of the XLPE insulation layer can effectively prevent short-circuit accidents; the stable conductivity of the high-purity copper conductor avoids potential safety hazards such as electric sparks caused by poor contact. In addition, the wear resistance of the black PVC outer layer also reduces the risk of electric shock caused by sheath damage.
Stable Transmission Performance
The excellent conductivity of the high-purity copper conductor is the basis for the stable power transmission of the cable. Both the 95 Sq mm 4-core cable and the 3*185+95mm² cable can transmit power stably under rated load. In the long-term use process, its transmission performance is not easily affected by external environmental factors, and it can provide continuous and stable power support for electrical equipment, reducing damage to equipment caused by power fluctuations.
(IV) Applicable Scenarios
Building Power Distribution
In the power distribution system of buildings, this cable can meet the power needs of different areas. It can be used for power transmission in residential buildings, commercial buildings, and office buildings. Its flexibility enables it to adapt to complex wiring directions inside buildings, such as laying in wall interiors and ceiling interlayers. At the same time, the safety characteristics of the LSZH sheath also meet the requirements of building fire safety.
Power Supply for Industrial Equipment
In industrial production, various large industrial equipment have high and stable power demands. This cable can provide reliable power supply for industrial equipment, such as machine tools, production lines, and lifting equipment. The temperature resistance and chemical erosion resistance of the XLPE insulation layer enable it to adapt to harsh conditions in industrial environments, such as high temperature, heavy dust, and chemical corrosion.
Other Scenarios
In addition to the above scenarios, the cable is also applicable to some special power transmission scenarios, such as subways, airports, and hospitals. In these places, there are high requirements for the safety, reliability, and flexibility of cables, and this cable can well meet these needs.
II. Analysis of Product Production Process
(I) Conductor Manufacturing Process
The manufacturing of the conductor starts with the selection of raw materials, using high-purity copper as the raw material. In the production process, the copper material is made into fine
Copper Wires through a series of processing steps. Then, a multi-strand stranded process is used to strand multiple fine copper wires together according to specific rules to form a conductor.
The multi-strand stranded process is not a simple superposition, but through precise calculation and control, each strand of copper wire is closely combined to ensure the integrity and stability of the conductor. This process not only enhances the flexibility of the conductor but also improves the mechanical strength of the conductor, making it not easy to break when subjected to external forces.
(II) Insulation Layer Processing Technology
The processing of the XLPE insulation layer adopts an advanced extrusion process. During processing, the XLPE material is heated to a molten state, and then it is evenly wrapped around the conductor through an extruder to form an insulation layer. The extrusion process can ensure that the thickness of the insulation layer is uniform, avoiding local uneven thickness, thereby ensuring the stable insulation performance of the insulation layer.
After extrusion, the insulation layer needs to be cross-linked. Cross-linking treatment can change the molecular structure of the XLPE material, making it form a three-dimensional network structure, thereby improving the high-temperature resistance, mechanical strength, and chemical corrosion resistance of the XLPE insulation layer.
(III) Sheath Manufacturing Process
The LSZH sheath and the black PVC outer layer are also manufactured by the extrusion process. First, the LSZH material is wrapped around the insulation layer through an extruder to form the LSZH sheath. Then, the black PVC material is extruded and wrapped around the LSZH sheath to form the outer sheath.
During the extrusion of the sheath, it is necessary to strictly control parameters such as extrusion temperature and speed to ensure the close combination of the sheath and the internal structure and avoid defects such as delamination and bubbles. At the same time, the appearance and size of the sheath must be strictly inspected to ensure that they meet relevant standards.
