low voltage 1 KV Heat Shrinkable Insulation Busbar tube for Electric Power System

1.Flame-retardant 2.Flexible 3.Thin-wall anti-track 4.Insulation and protection of bus bar 5.Low voltage busbar tube

Introduction

The Low voltage heat shrinkable bus bar tubing provides

both insulation and protection of bus bar, reduces bus bar

spacing requirements, anti-track, protects against accidental  

flashover, and provides protection against corrosion for big size

metal tube.
