Silicone Conductor Covers & Insulating Sleeves for Power Utilities
Manufactured by Centroid Polymer Technologies in Kerala, India
Wildlife contact and vegetation are among the most common causes of outages on overhead distribution lines. Insulating the bare conductor at the right points prevents flashovers and protects animals.
Centroid manufactures silicone insulating sleeves in button-lock, press-lock, double-lock and self-lock designs, plus formed covers for bushings, busbar junctions, arresters, fuse caps and pin insulators.
The sleeves fit without tools onto bare conductors, often without disconnecting the line. Silicone's hydrophobic, UV-stable surface keeps them insulating for years outdoors.
What Power & Utilities buyers need
- Wildlife and vegetation outage prevention
- Tool-free, live-line compatible installation
- UV, ozone and tracking resistance outdoors
- Fit across a range of conductor sizes
- Covers for bushings, arresters and busbar junctions
Standards commonly specified
- IEC 60502
- IEC 62217

Frequently asked questions
Which locking type should I choose?
Button-lock and press-lock sleeves are quick to fit on distribution lines. Double-lock gives extra retention on catenaries and in high-wind areas. Self-lock sleeves wrap and hold without fasteners.
Can the sleeves be installed on live lines?
They are designed for field installation on bare conductors, often without disconnecting the line. Always follow your utility's live-line working procedures.
Do you make covers for transformer bushings?
Yes. We supply formed silicone covers for bushings, terminals, arresters, fuse caps and busbar junctions.
