HT & LT Switchgear Panels

HT & LT Switchgear Panels are critical components of electrical power distribution networks. They provide safe switching, protection, monitoring, and control of electrical power from incoming supply sources to various loads.

HT (High Tension) Switchgear Panels are used for medium/high voltage systems, typically installed on the primary side of transformers to control and protect power distribution equipment. They include components such as circuit breakers, isolators, protection relays, CTs, PTs, and busbars.

LT (Low Tension) Switchgear Panels are used on the low-voltage side of transformers for distributing electrical power to buildings, machinery, lighting systems, and other connected loads. LT panels include MCC panels, PCC panels, distribution boards, capacitor panels, and feeder panels.

These systems are widely used in factories, commercial buildings, power plants, substations, hospitals, shopping malls, and large infrastructure projects.
