Power Cable

Introduction

Sai Extrumech power cable extrusion lines are built for low-voltage (LV), medium-voltage (MV) and high-voltage (HV) power transmission and distribution cables. Unlike thin-wall data cable lines, these handle large conductors and thick insulation walls, with the option of triple-layer extrusion for MV cables that require a semiconducting conductor screen, XLPE insulation, and an insulation screen applied in a single pass.

Lines are typically built around 90–150mm extruders at 24:1–28:1 L/D, with CCV (catenary continuous vulcanisation) or silane crosslinking for XLPE, and PVC handling for LV cables to IS 694 and IS 7098. Robust haul-off and large-drum take-up systems manage the weight of heavy-gauge cable, while precise melt-pressure control keeps insulation wall thickness and concentricity within IEC 60502 limits.

Applications:

  • Power grids and distribution networks
  • LV/MV building and substation feeders
  • Industrial plant power distribution
  • Renewable energy evacuation (solar, wind farms)

Why Sai Extrumech: We engineer the complete line — extruder, triple-layer crosshead, cooling and take-up — matched to your voltage class and conductor range, and supply replacement screws, barrels and tooling for existing lines.
