HT Switchgear
HT Switchgear
Description
HT Switchgear, or High Tension Switchgear, is designed for controlling, protecting, and isolating electrical equipment in high-voltage systems. Used primarily in industrial, commercial, and utility sectors, it ensures safe and efficient power distribution by protecting circuits from faults and managing high-voltage electrical loads.
Specification

- Components: Circuit breakers, isolators, earthing switches, transformers, protection relays
- Interrupting Capacity: Varies based on design, typically from 16 kA to 63 kA
- Insulation Type: Air-insulated, gas-insulated (SF6), or vacuum-insulated, depending on application
- Frequency: 50 Hz or 60 Hz
- Protection Level: IP54 or higher for safe operation in various environments
- Applications: Power plants, substations, industrial facilities, and large commercial buildings
- Standards: IEC 62271 for high-voltage switchgear and control gear
