GW4 Isolation Switch 27.5 kV Isolation Switch (also known as Disconnector)
The 27.5kV GW4 series isolating switch is designed specifically for railway overhead contact systems and specific high voltage scenarios
Conductive circuit: Soft connection of copper tubes reduces mechanical stress, and optimized contact pin spring pressure ensures contact stability.
Insulation Configuration: Anti-scale ceramic insulator with creep distance ≥ 31mm/kV (designed for pollution class III), suitable for harsh environmental conditions such as humidity and salt fog.
Typical Application Scenarios
- Railway overhead catenary: Isolation of line segmentation and equipment maintenance of electrified railway power supply system, such as dead zone switching in overhead line catenary system.
- Substation Isolation: Used in conjunction with circuit breakers in 27.5 kV distribution lines to form visible trip points.
- Industrial power distribution: power isolation and equipment protection in high current environments, such as in metallurgy and mining.
The 27.5 kV isolation switch is adapted to railway and industrial environments thanks to its customized design (eg anti-fogging and high current characteristics). When choosing, special attention should be paid to the rated current, type of operating mechanism and suitability to the environment.
