Bay-O-Net Fuse Holder for Transformer Protection
The Bay-O-Net Fuse Holder is Used to hold oil-immersed externally replaceable bayonet expulsion fuses in pad-mount applications up to 23kV150kV BIL, 38kV 200BIL.
When fault conditions occur, the fuse link interrupts the circuit to isolate the transformer and prevent equipment damage. The device allows operators to safely remove and replace fuse links without opening the transformer tank.
Structural composition of:
- Bay-O-Net outer housing
- Removable fuse cartridge holder
- Fuse link or dual-sensing fuse
- Contact assembly
- Oil-sealed insulated tube
- Hot-stick operable handle
Key Features
Dead-Front Safety Design
Designed for safe operation in energized distribution systems, minimizing exposure to live components.
Hot-Stick Operable
Enables easy fuse replacement using standard hot-stick tools without tank opening.
Excellent Overcurrent Protection
Provides reliable transformer protection against overloads and low-level fault currents.
Coordination with Current-Limiting Backup Fuses
Can be used in series with current-limiting fuses for enhanced fault interruption capacity.
Oil-Immersed Insulation Structure
Suitable for mineral oil and approved insulating fluids used in pad-mounted transformers.
Easy Installation & Maintenance
Simple structure reduces maintenance time and operational downtime.
Wide Compatible Fuse Links
Dual sensing fuse links; Current sensing fuse links; Dual element fuse links.
