Many customers are not very clear about the standards of wires and cables when choosing wires and cables. The following Jinke Cable Xiaobian gives you a brief introduction and hopes to help you Voltage grade of irradiated crosslinked power cable: 0.6/1 kV;; Implementation standard: GB/T12706.1-2002 Irradiation cross-linked cable is to use high-energy rays to bombard hydrogen atoms in its molecular chain and discharge them, so that gaps in the molecular chain form a network of macromolecular three-dimensional structure and form cross-linked polyethylene; Voltage grade of medium voltage XLPE insulated power cable: 6/6 kV-26/35 kV;; Implementation standard: GB/T12706.2-2002 The mechanical properties, thermal aging properties and environmental stress capacity of medium voltage cross-linked polyethylene cable are greatly improved by using full dry chemical cross-linking method; High Voltage XLPE Insulated Power Cable Voltage Class: 64/110 KV Executive Standard: GB/T 11017; 127/220 KV290/500KV XLPE cable has better gas performance dielectric loss than paper insulation and PVC insulation are smaller XLPE cable capacitance is also small; Control cable implementation standard: GB9330-88; Voltage class: 450/750 V The product adopts PVC or irradiated crosslinked polyethylene as insulating layer with excellent electrical conductivity, mechanical properties and chemical stability. It is suitable for protection occasions such as protection circuit for control and monitoring circuit with rated voltage of 0.6/1KV and below; National standard wires are wires produced according to national standards General household common wires are in line with the national standard of standard specifications and performances, which stipulates five common specifications and performances Appearance standard, there must be certification mark on the wire, manufacturer's wire diameter, etc., and yellow-green insulation layer for the ground wire; Mechanical strength; Insulation of sheath (generally greater than 100 M Ω) and compressive strength (below 500V and 1500V); Line resistance (no more than a certain resistance under a certain line diameter conductivity length); High temperature impact at 150 degrees and low temperature at-30 degrees, the wire shall not crack, etc.
