Complete Cable Plant Turnkey Specification

The reliability of high-voltage power cable operation is an important guarantee for the safety of the power grid. However, in recent years, high-voltage corrugated aluminum sheathed cables operating in power transmission systems in many places have repeatedly suffered from electrical corrosion. In severe cases, they will cause cable breakdown, posing serious hidden dangers to the safe operation of the power grid.

This paper mainly introduces the equipment and technology of the copper strip longitudinal welding continuous production line, which solves the problem of short cable length, shortens the production cycle, reduces costs and improves production efficiency. It also introduces the difference between rolling and drawing in the manufacture of mineral insulated cables.

Wires and cables are made through three processes: drawing, twisting, and coating. The more complex the model and specifications, the higher the repeatability.
