33kV Silicone Gang Insulator
Silicone composite insulator for gang operated switching arrangements
Product Overview
A gang operated switch moves all three phases together from one operating mechanism, and the insulators in that arrangement have to carry both the electrical duty and the mechanical operating load. The silicone composite construction keeps the surface performance in polluted air while keeping the moving assembly light enough to operate smoothly.
Key Benefits
- Supports the electrical and mechanical duty of a gang operated arrangement
- Silicone surface holds hydrophobicity in polluted wet conditions
- Composite construction keeps the operating assembly light
- Does not shatter under the shock loads of switching operation
Problems It Solves
- Flashover across switching insulation in polluted conditions
- Ceramic insulation cracking under repeated switching shock loads
- Heavy assemblies that make gang operation stiff
Application Scenarios
- Gang operated air break switch positions
- Sectionalising points on distribution feeders
- Switching arrangements at substation take-off structures
- Replacing ceramic insulation in existing switching assemblies
Who It Is For
- Distribution utilities operating gang switches
- Substation and line construction contractors
- Maintenance departments refurbishing switching positions
- EPC companies delivering sectionalising points
Technical Features
- Silicone rubber composite construction
- Rated for gang operated switching arrangements
- Carries mechanical operating loads
- Listed at 33kV

Compared With Other Options
| Porcelain switching insulator | Porcelain is stable under UV but brittle under repeated switching shock. Composite handles the shock loading and the pollution. |
|---|---|
| Standoff insulator | A standoff carries a static position. A gang insulator carries the mechanical duty of an operating switch. |
Use Guide
- Confirm the end fitting arrangement against the switch mechanism before ordering
- Check the operating mechanism moves freely after installation
- Inspect for surface tracking and mechanical wear at maintenance
- Do not substitute an insulator not rated for the mechanical duty

Can this insulator be used on a static position
It can, but it is specified for the mechanical duty of a gang operated arrangement. For static positions the standoff range is the direct answer.
Can end fittings be made to our drawing
Yes - our engineering team develops items to customer drawings where the catalogue arrangement does not match the mechanism.
