Designed for GCK series low voltage withdrawable switchgear, widely used in power plants, substations, industrial facilities, and high-rise buildings for both Power Center (PC) and Motor Control Center (MCC) applications.
Suitable for AC 50–60Hz systems up to 660V and rated currents up to 3150A, this insulator provides reliable insulation and mechanical support for main busbars and vertical busbars in power distribution, motor control, and reactive power compensation systems.
Features high mechanical strength, excellent creepage distance, and compatible mounting dimensions, ensuring safe operation under short-circuit conditions and demanding environments.
