Product Overview

The COMPAQ CHRB/CHSB Series Heat Shrinkable Boots are designed to insulate and protect bushings in air-insulated cable-end boxes integral with medium voltage switchgear and transformers up to 36kV.

Available in Right Angle (CHRB) for 90° layouts and Straight (CHSB) for inline configurations, these boots provide surge and flashover protection in high-humidity, rodent-prone, and polluted environments. The combination of cross-linked polyolefin construction and internal hot-melt adhesive coating ensures a secure moisture seal, long-term dielectric strength, and reliable performance in both indoor and outdoor installations.

How Are We The Best

Product Benefits?

Two Configurations

CHRB for right-angle terminations; CHSB for straight-line layouts – offering installation flexibility in compact or standard switchgear arrangements.

01

Flashover & Surge Protection

Shields terminations from flashovers caused by humidity, rodent ingress, or transient overvoltages.

02

High-Performance Material

Cross-linked, thermally stabilised polyolefin for superior mechanical and electrical performance.

03

Integrated Adhesive Lining

Hot melt adhesive ensures moisture-tight sealing and enhanced dielectric integrity.

04

Weather & UV Resistance

Suitable for indoor and outdoor service in polluted and harsh environments.

05

Medium Voltage Rated

Designed for insulation applications up to 36kV.

06

Quick Installation

Shrinks evenly using a gas torch or hot air blower, reducing downtime.
