Primary Air Insulated Switchgear

MV switchgear is a full range of primary or secondary distribution equipment for controlling, protecting and isolating power distribution systems across utility, commercial and industrial applications. It uses Air, Gas, or Shielded Solid Insulated technologies to minimize and extinguish any electrical arc created during electrical switching.

With AIS, GIS, and 2SIS technologies, users benefit from a wide choice of switchgear architectures that add the latest protection, automation and IoT connectivity to MV equipment.

Why is MV switchgear equipment used?

Switchgear is used to detect, clear, and isolate faults from any downstream connected electrical equipment, protecting them from overloads and allow smooth business operations. MV Switchgear is housed in a metal enclosure containing key components such as circuit breakers, switches, fuses, cable incomers, feeders, and busbars.

It operates between 3 kV to 36 kV and contributes to the overall stability of electrical grids through the advanced detection and isolation of many conditions, from general overloads and short circuits to arc-flash, thermal hotspots, and circuit breaker health.

Modular MV switchgear from the SeT series for primary and secondary power distribution up to 36kV and up to 72 kV.

Benefits of using MV Switchgear

MV Switchgear is essential in businesses that consume large amounts of power, from utility to commercial businesses and industries. It provides a disconnection point from the upstream electrical grid that can be isolated for maintenance, automated for backup auto-transfer solutions or integrated with micro-grids to manage renewable energy.
