I. Introduction 
 Transmission and distribution system for power cables, the company produces PVC insulation rated voltage 0.6/1KV 35KV and below power cables and XLPE power cable, its performance is not only the standard GB1276 and IEC60502 and IEC60840, and has formed a series , that is flame retardant, and fire-resistant type, cold type and water type power cable. 
 In the flame-retardant products, the successful application of the oxygen barrier technology, not only 0.6/1KV PVC insulation and flame-retardant XLPE insulated power cables can reach GB/T12666.5 "power cable bundle fire test method "in the A category, and rated voltage 6/10KV and 8.7/15KV retardant XLPE power cables can reach A class of flame retardant and have a greater margin. In high fire-retardant XLPE also developed on the basis of halogen flame retardant and oxygen barrier of high power cable, and its performance in line with national standards GB/T17651.1.2 halogen and GB/T17650.1.2. That the company XLPE power cable is lower than the overall level of the domestic leading position. 
 The company's fire rated voltage power cable 0.6/1KV copper cable, can also produce fire-resistant low smoke zero halogen power cables, high oxygen barrier fire retardant power cable, and its fire resistance compliance GB/T12666.6 "wire cable fire performance test method. " Therefore, fire series power cable performs well. 
 Fire performance cables meet the IEC502-2 water-blocking requirements.
