Anti Tracking / Non Tracking Heat Shrink Sleeve – High Dielectric Insulation | Safe Cable Connect

High Dielectric Insulation – Safe Cable Connect

​

Product Summary

The Anti Tracking / Non Tracking Heat Shrink Sleeve from Safe Cable Connect is a high-performance electrical insulation solution for medium voltage (MV) and high voltage (HV) cable systems. It is specially designed to prevent surface tracking, leakage paths, corona discharge, and electrical erosion.

This sleeve features a black anti-tracking outer layer and a red high-insulating inner layer, providing excellent dielectric strength and long-term reliability. It is widely used for cable joints, terminations, and stress control applications in power distribution networks.

​

Key Features

  • Dual layer construction (black anti-tracking outer layer and red insulating inner layer)

  • High resistance to electrical tracking and surface arcing

  • Very high dielectric strength

  • Uniform heat shrinking without cracking

  • Excellent resistance to moisture, UV, and chemicals

  • Smooth finished surface

  • Long service life in harsh environments

  • Compatible with MV heat shrink joint and termination kits

​

What Is Anti Tracking / Non Tracking?

Tracking is the formation of conductive paths on insulation surfaces due to moisture and electrical stress. Anti tracking or non tracking sleeves are engineered to resist this surface degradation, helping prevent flashover, surface arcing, carbonisation, and insulation failure. This improves operational safety and extends cable life.

​

Product Description

The Anti Tracking / Non Tracking Heat Shrink Sleeve is manufactured from specially formulated polymers for enhanced tracking resistance.

The red inner layer provides primary electrical insulation with high dielectric strength.
The black outer layer offers superior surface protection and anti-tracking performance.

When heated using a heat gun or oven, the sleeve shrinks tightly over cables, joints, or terminations, restoring insulation integrity and eliminating leakage paths.
