FCR-36 DROP OUT FUSE (CERAMIC)

New Products / New Technology

FCR-36 drop out fuse is a short-circuit protection switch used for distribution lines and primary side of distribution transformers, It has the characteristics of economy, easy operation, and strong adaptability to outdoor environments. It is widely used in branch lines of 10-35kV distribution lines and the primary side of distribution transformers, for overload and short-circuit protection, and can switch rated load currents.

Technical parameters and performance characteristics
Rated voltage: suitable for power systems ranging from 10-35kV.
Protection function: It has the functions of short circuit protection, overload protection, and isolation circuit.
Working environment: Suitable for power systems with a frequency of 50Hz, capable of working normally at ambient temperatures ranging from -30 ℃ to+40 ℃, with an altitude not exceeding 1000m and a maximum wind speed not exceeding 35m/s.

Structure composition and usage method
The FCR-36 drop out fuse mainly consists of high-strength insulators, parallel groove connection terminals, upper contacts, fuse tubes, and other components. Its working principle is that during normal operation, the fuse tube is tensioned by the fuse to form a closed position; When the system malfunctions, the fault current causes the fuse to quickly melt, forming an arc that is then extinguished by the arc extinguishing cover, and the fuse tube drops to form a clear breaking position.

Maintenance and upkeep suggestions

GW1-12/630A HIGH VOLTAGE ISOLATION SWITCH

New Products / New Technology

Product overview
The GW1 outdoor high-voltage isolation knife switch GW1-12/630A (hereinafter referred to as the isolation switch) is suitable for installation on outdoor 12KV lines for the purpose of closing the line when there is voltage and no load.
This isolation switch fully considers the different needs of users and comes in two forms: with grounding knife and without grounding knife. A switch with a grounding knife and a CS type manual mechanism can prevent misoperation such as hanging a grounding wire while live and closing an isolation switch with a grounding wire. Operators do not need to hang another grounding wire. This isolation switch has two types: ordinary type and anti fouling type. Among them, the anti fouling isolation switch can meet the requirements of severely polluted areas and effectively solve the problem of pollution flashover during the operation of the isolation switch. The product meets the requirements of standards such as GB1985 and GB/T11022.

Environmental conditions for use:
1. Altitude not exceeding 1000M;
2. The upper limit of ambient temperature is 40 ℃, and the lower limit is -25 ℃;
3. Places without conductive or chemically reactive gases and vapors;
4. Places without fire, explosion hazards, or serious pollution;
5. Places that are not subjected to severe vibrations or impacts (such as near electric picks or dredgers).

PRWG2-40.5 DROP OUT FUSE (SILICONE)

New Products / New Technology

Product overview
PRWG2-40.5 drop out fuse is an outdoor high-voltage protection device, mainly used on the high-voltage side of distribution transformers or distribution line branch lines, for short-circuit and overload protection of transformers and lines, as well as for breaking and closing load currents.
The fuse consists of an insulation bracket and a fuse tube. The static contacts are installed at both ends of the insulation bracket, and the moving contacts are installed at both ends of the fuse tube. The fuse tube consists of an inner arc extinguishing tube and an outer layer of phenolic paper tube or epoxy glass cloth tube.

Performance characteristics
Scope of application: Suitable for overload and short-circuit protection of transmission lines and power transformers in power systems with voltage of 40.5kV and below and frequency of 50Hz.
Mechanical lifespan: The mechanical lifespan of the rated load current for opening and closing should be ≥ 2000 times.
Easy installation: Adopting a single column structure, it is easy to install.
Protection feature: Based on the principle of extinguishing the arc through single end step-by-step exhaust, it can effectively and reliably disconnect the minimum load current to the maximum fault current within the rated value, with safe, reliable, and full range disconnection protection features.
