35-220kV Cable Extrusion Line, Triple Extrusion

Baicheng's vertical continuous vulcanization line (VCV line) is designed in response to the popularity of XLPE cables in high voltage application. In particular, the quality of high voltage and extra high voltage power cables plays an essential role in the safety of electric system.

This vertical cable extrusion line is particularly used for manufacturing high quality XLPE insulated power cables of voltages ranging between 35kV and 220k. It mainly comprises pay-off stand, accumulator, capstan, extruder, three-layer crosshead, take-up stand, etc.


Features
  • Manufacturing the full range of medium voltage (MV) to extra high voltage (EHV) cables;
  • Triple extrusion process for XLPE insulation;
  • Capable of manufacturing power cables used for a variety of applications;
  • Long and stable production runs;
  • L-type and U-type are available;
  • Triple crosshead provides great convenience and ease of alignment;
  • Customer-specific modified versions are available to suit individual requirements;

Extruder & Crosshead

Triple extrusion lines have three extruders connected to one common three-layer crosshead for the simultaneous extrusion of conductor screen layer (inner semiconductor layer), insulation layer and insulation screen layer (outer semiconductor layer).


Control System

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.
