11kV Silicone Drop Out Fuse
Pole mounted 11kV drop out fuse with a silicone composite housing
Product Overview
An 11kV drop out fuse isolates a downstream fault and shows the crew which position operated - the carrier swings clear and is visible from the ground. The silicone composite housing means the unit keeps working in polluted wet air where a porcelain surface would wet out, and it is light enough to be mounted at the pole top without lifting plant.
Key Benefits
- Visible open position identifies the operated fuse from the ground
- Silicone housing keeps a hydrophobic surface in wet polluted air
- Composite construction is light enough for pole top handling by hand
- Does not shatter if dropped during transport or installation
Problems It Solves
- Pollution flashover across the fuse housing in coastal or industrial air
- Ceramic units broken in transit to remote sites
- Faults that cannot be located quickly from the ground
Application Scenarios
- Protection of 11kV pole mounted transformers
- Sectionalising points on 11kV distribution feeders
- Spur line protection from a main feeder
- Replacing porcelain drop out fuses that keep failing on pollution
Who It Is For
- Distribution utilities operating 11kV networks
- Rural electrification contractors
- Line maintenance crews
- EPC contractors building 11kV distribution
Technical Features
- Silicone rubber composite housing
- Drop open carrier giving visible indication
- Rated at 11kV for distribution positions
- Pole mounted arrangement

Compared With Other Options
| 36kV porcelain drop out fuse | Porcelain at a higher class for projects that require a ceramic housing. The silicone version wins on weight and pollution performance. |
|---|---|
| 33kV silicone drop out fuse | Same construction at the higher distribution class. Select on the feeder voltage. |
| Combi unit | A combi unit carries both drop out fuse and surge arrester functions where the position needs both. |
Use Guide
- Confirm the fuse link rating against the protection study for the position
- Mount so the carrier drops clear without fouling the structure
- Keep the earth connection short and direct
- Record the installed rating at each position for future ordering

11kV Silicone Drop Out Fuse Questions
Does the silicone housing need washing
The hydrophobic surface is what removes the need for the washing regime a porcelain surface requires in a polluted environment.
Can this be used at 33kV
No. Use the 33kV unit for 33kV feeders - the class is a design limit, not a margin.
Are fuse links supplied with the unit
Confirm the link rating in your enquiry so the correct links are quoted with the fuses.
