For this question, at present, the major cable factories in China, including our own company, basically use chain type units and three layers of coextrusion to produce 16mm armoured cable (cross-linked cables). At present, there are four types of layout of underground cable: horizontal, tilting, catenary, and vertical type. One of the most conducive to the production of XLPE cable is vertical type, next should be chain,tilting, and horizontal. But because the vertical type asks for high demand of plant and
The 33kv underground cable consists of these basic structures: conductors, internal shielding, insulation, and external shielding. So the first factor that affects the efficiency of production is the amount of glue produced by the three extruders. The second factor is the length and temperature of the pipe. Temperature is an important condition that affecting the Modification of Polyethylene. Therefore, it has become the most important restriction condition for the production speed of 3kv cross linked cable
