Semiconductive Tape

Woven Semi Conductive Tape (for Conductor)

Construction:-

  • This is woven tape produced using a robust fibre coated with semiconducting compound on both sides

End Use Applications:-

  • Used as a binder tape over the conductors of MV, HV and EHV Power Cables involving processing of XLPE insulation under high temperature and pressure on CV lines.
  • Suitable for use as a binder tape of large sized Milliken conductors.
  • Enhances the insulation performance of cable by creating a smooth interface between the conductor and insulation.

Woven Semi Conductive Tape (for Core and for multipurpose use)

Construction:-

  • This is woven tape produced using a strong fibre coated with semiconducting compound on both sides.

End Use Applications:-

  • Semi-conductive tape is used to equalize the electric field and reduce voltage stress.
  • Used over the insulation of LT & MV Power Cables for facilitating uniform electrical field.
  • Used over the armour / screen wires as a bedding or separation tape applications.
