40.5Kv Current Limiting Fuse for High Voltage Equipment TUV certified
Oil Immersed Fuse Manufacturer Factory Direct Sale High Quality with Competitive Price
Product Description

This kind of switch applies to single-phase, three phase , combination oil-immersed transformer electrical power with frequency of 50HZ,,60HZ,rated voltage of 10KV,35KV,rated current of 30A ~500A; the voltage-regulating mode are: central part, terminal point neutral point, which can be directly fixed on the tank cover of the transformer, exchange under the off-circuit condition.
Bay- O-Net Assembly is the brief element of oil-transformer, to protect the equipment when over-current. When install the fuse wire in it, the Bay-O-Net will provide the safe, highly efficient protection, according to the current, oil-femperature.
The Bay-O-Net Assembly is suitable for current sensing fuse wire, dual sensing fuse wire, dual element fuse wire, and ELSP current-limiting backup fuse, etc.
It is suitable for high-voltage power system with alternating current of 50Hz,standard voltage of 15. 5kV, current rating of 140A. It must be combining with MagnX Interrupter of ELSP Current-Limiting Backup Fuse to protect transformer from overload and short circuit.
