APPLICATIONS OF MEDIUM VOLTAGE SWITCHGEAR
Our medium voltage switchgear solutions are used across a wide range of industries and facilities.
KEY COMPONENTS OF MEDIUM VOLTAGE SWITCHGEAR
Medium voltage switchgear is built around eight core components that work together to ensure safe switching, reliable protection, effective control, and stable power distribution.
Circuit Breakers / Load Switches
Used to make, carry, and interrupt current under normal operating and fault conditions
Fuse Units
Used to provide overcurrent protection and help limit fault energy in compact switchgear arrangements.
Protection Relays & Secondary Control
These components handle signaling, protective action, control logic, and auxiliary functions required for reliable system operation.
Disconnectors (Isolators)
Used to isolate sections of the circuit so inspection and maintenance can be carried out more safely
Busbars & Cable Connections
Busbars distribute power within the switchgear, while cable connections link the cabinet to incoming and outgoing circuits.
Indicators & Safety Devices
Voltage indicators, fault indicators, pressure indicators, interlocks, and pressure relief devices help operators monitor equipment status and improve operational safety.
Earthing Switches
Used to ground isolated parts of the system and improve operator safety during servicing.
Instrument Transformers
Current transformers and voltage transformers support metering, protection, and monitoring by converting electrical values into usable signals.
