Component Specifications

Definition
A metallic or conductive component installed in high-voltage insulated cable terminations to create an equipotential surface, safely channeling leakage currents and capacitive discharge to ground, thereby preventing dangerous voltage gradients, corona discharge, and insulation breakdown at the termination interface.
Working Principle
Operates by establishing a controlled conductive path between the cable's outer semiconductor layer or metallic sheath and the grounding system. It equalizes electrical potential across the termination surface, suppresses partial discharges, and directs any surface currents safely to earth, maintaining the integrity of the insulation system.
Materials
Typically made from conductive materials such as copper, aluminum, or tin-plated copper alloys, often with a corrosion-resistant coating. May include conductive elastomers or polymers for specific applications. Must have low electrical resistance and good mechanical durability.
Technical Parameters
  • Resistance < 0.1 ohm
  • Compatibility Designed for specific cable diameters and insulation types
  • Voltage Rating Up to 36 kV or higher as per design
  • Temperature Range -40°C to +90°C
  • Installation Method Slip-on, clamp, or adhesive-based
Standards
IEC 60502-2, IEEE 48, DIN VDE 0278-629
