Baicheng offers horizontal continuous vulcanization (CV) lines that are designed for continual extrusion of products with rubber insulation, especially to produce rubber cables of voltage up to 35kV.
This line is equipped with 3 extruders and one common crosshead, capable of extruding three layers of conductor screen layer, insulation layer and insulation screen layer in one single operation. The finished MV cables support a voltage rage between 6Kv and 35kV, which are ideal for use in power distribution and transmission lines.

The control system makes sure the entire VCV line run synchronously. All the electrical drive systems can work simultaneously, or to be controlled independently by single machine. Emergency stop is possible for individual units such as pay-offs, accumulators, extruders and take-ups respectively.
