Do you know the difference between cross-linked polyethylene insulated cables and ordinary insulated cables? What are the advantages of cross-linked polyethylene insulated cables compared with general insulated cables? The following introduces the differences between them.
The difference between ordinary insulated cables and cross-linked polyethylene insulated cables
1. Cross-linked polyethylene insulated cables are made of different materials than ordinary insulated cables.
2. Temperature resistance: The temperature resistance of general insulated cables is usually 70°C, and the temperature resistance of cross-linked polyethylene insulated cables can reach 90°C.
3. Different carrying capacities: For cables with the same conductor cross-sectional area, the carrying capacity of cross-linked polyethylene insulated cables should be greater than that of general insulated cables.
4. Application scope: Generally, insulated cables will release toxic HCL smoke when burning. Do not use ordinary insulated cables when fire protection requires low toxicity. Cross-linked polyethylene insulated cables can be used in power distribution networks, industrial equipment or other areas requiring large-capacity power.
5. Transmission and distribution lines with DC 50Hz and rated voltage 6kV~35kV are fixedly laid, and their main function is to transmit electric energy.
Advantages of cross-linked polyethylene insulated cables
Cross-linked polyethylene insulated cable is a cable suitable for distribution networks and other fields. It has advantages that PVC insulated cables cannot match. It has a simple structure, light weight, heat resistance, strong load-bearing capacity, no fusion, chemical corrosion resistance and high mechanical strength.
Cross-linked polyethylene is a cross-linked polyethylene that converts a linear molecular structure into a three-dimensional network structure through chemical or physical methods. Greatly improves the thermomechanical properties of polyethylene and maintains good electrical properties.
The rated operating temperature of the conductor of the cross-linked polyethylene insulated cable can reach 90°C, which is higher than that of PVC insulated and polyethylene insulated cables, further improving its carrying capacity. The cross-linked polyethylene insulated cable has excellent thermodynamic properties and excellent electrical properties. It has the advantages of chemical corrosion resistance, simple structure, light weight and unlimited laying. It is widely used in urban power grids, mines, factories and mines and other fields.
