Silicone Composite Insulators Fuses and Surge Arresters
Silicone housed pole-top equipment for 11kV and 33kV lines in polluted coastal or industrial air.
Silicone rubber housed equipment - drop out fuses, combi units, surge arresters, gang operated and standoff insulators, J hook and pot insulators - rated at 11kV and 33kV. The silicone housing sheds water and resists surface tracking, and the composite core makes a unit that a two-man crew can lift onto a pole without a lifting aid.

View details →Who This Family Is For
- Utilities running lines through coastal salt spray or industrial fallout
- Rural electrification crews working far from a maintenance depot
- Buyers replacing porcelain that keeps failing on pollution flashover
- Projects where transport breakage of ceramic parts has become a recurring cost
Problems It Answers
- Hydrophobic silicone housing keeps a dry band on the surface in wet and polluted conditions
- Composite construction weighs less than the porcelain equivalent, which shortens pole-top work
- Does not shatter on impact, so transport and handling losses drop on remote sites
- 11kV and 33kV versions of the same item type, so one drawing set covers both feeders
Where It Gets Used
Coastal 33kV feeders exposed to salt spray
Lines passing cement works, refineries or fertiliser plants
Island and mountain lines where a maintenance visit is a day's travel
Replacing repeatedly failing porcelain insulation on an existing line

Porcelain or Silicone Composite Insulators How to Decide
The choice is decided by pollution, weight and handling losses rather than by price per unit.

Drop Out Fuses and Surge Arresters on a Distribution Pole
What each device protects against and why a pole-mounted transformer normally needs both.
Read guide →Silicon material Questions
Why choose silicone composite over porcelain
Two reasons dominate: pollution performance and weight. Silicone stays hydrophobic in a polluted wet environment where a porcelain surface wets out and flashes over, and a composite unit is light enough to handle at the pole top without lifting equipment.
Which voltage classes are available
The silicone range in this catalogue is listed at 11kV and 33kV. A 36kV porcelain drop out fuse is listed in the same section for projects that need a ceramic housing at that class.
Do you supply the complete drop out fuse assembly
The drop out fuses and combi units are supplied as units. Fuse links and fuse bases are listed separately under Fuse & Base so replacement links can be ordered on their own.
