ANTI TRACKING TUBE

3M™ Heat Shrink Anti-Tracking Tubing (ATT Series)

3M™ Heat Shrink ATT Series Tubing is specifically engineered to perform under demanding outdoor environments and rigorous operational conditions. Designed for medium-voltage power cable end terminations and busbar insulation, ATT Series tubing is manufactured from a specially formulated, non-tracking polyolefin compound that offers exceptional electrical stability, weatherability, and physical strength.

Manufactured at 3M's state-of-the-art facility in Pune, it provides superior surface resistance to electrical tracking, surface erosion, and long-term environmental degradation.

Key Features & Benefits

  • Exceptional Anti-Tracking Properties: Formulated to resist surface tracking, erosion, and electrical discharge under humid, polluted, or coastal outdoor conditions.
  • UV & Weathering Resistant: Highly resistant to ultra-violet radiation, ozone, and severe weather exposure, ensuring a extended service life.
  • Superior Mechanical Strength: Highly durable polyolefin construction offers high tensile strength and tear resistance to protect against external abrasion and mechanical stress.
  • Versatile Application Range: Suitable for insulating busbars in switchgear, as well as protecting medium and high-voltage cable terminations up to 33 kV.
  • Uniform Shrinkage & Fit: Shrinks evenly upon heating to form a tight, smooth, and void-free protective sleeve around irregular cable profiles and busbar joints.
