The insulation of the cable is cross-linked polyethylene, which is transformed into a three-dimensional network of cross-linked polyethylene by chemical methods, thus greatly improving the mechanical properties of polyethylene and maintaining excellent electrical properties.
So do you know the difference between XLPE insulated cable and ordinary insulated cable? What are the advantages of XLPE insulated cable compared with ordinary insulated cable? The following Asian cable to talk to you about the difference between crosslinked polyethylene insulated cable and ordinary insulated cable.
1. Material difference between cross-linked polyethylene insulated cable and ordinary insulated cable.
2, temperature resistance performance: the temperature resistance level of ordinary insulated cable is generally 70°C, and the temperature resistance of crosslinked polyethylene insulated cable can reach 90°C.
3. Different flow rate: for cables with the same conductor cross-sectional area, the flow rate of XLPE insulated cable should be greater than that of ordinary insulated cable.
4, scope of application: ordinary insulated cable in combustion, will release toxic HCl smoke, fire protection requirements of low toxicity can not use ordinary insulated cable. Xlpe insulated cable is suitable for distribution network, industrial installation or other areas requiring large capacity electricity. It is used for fixed laying on power transmission and distribution lines with AC 50Hz and rated voltage of 6kV ~ 35kV. Its main function is to transmit electric energy.
Advantages of cross-linked polyethylene insulated cable:
(1) Crosslinked polyethylene is a kind of crosslinked polyethylene that transforms linear molecular structure into three-dimensional network structure by chemical or physical means. To a large extent, it improves the thermo-mechanical properties of polyethylene and maintains excellent electrical properties.
(2) The rated working temperature of the conductor of the cross-linked polyethylene insulated cable can reach 90℃, which is higher than that of the PVC insulated cable and polyethylene insulated cable, so as to further improve the bearing capacity of the cable.
(3) XLPE insulated cable has excellent thermal and mechanical properties, excellent electrical properties and chemical corrosion resistance, and has the advantages of simple structure, light weight and unlimited laying. It is a new type of cable widely used in urban power grid, mines and factories.
