What are the possible causes of cracking failure in CT terminal blocks within GIS equipment?
Gas - insulated switchgear (GIS) , often called “SF6 combined electrical apparatus”, is widely used in power systems for its high reliability, small footprint, low noise, and low loss. It encloses high - voltage devices like circuit breakers, fast grounding switches, current transformers, and busbars in a grounded metal shell filled withSF6gas. Each device sits in a separate gas chamber with different pressures. The CT terminal block divides gas chambers, connects components, and eas
