A Primary & Secondary Integrated RMU combines medium-voltage switchgear with intelligent secondary equipment such as protection relays, control systems, communication modules, and Distribution Terminal Units (DTUs). It enables automated monitoring, protection, and remote control of power distribution networks.

A centralized DTU collects operating data from multiple feeder units, supports remote monitoring and fault isolation, and improves the efficiency and reliability of distribution automation systems.

Each RMU featured a 2-inlet, 4-outlet configuration with SF₆ insulation, centralized DTU, vacuum circuit breakers, and a stainless steel enclosure, providing a compact and reliable solution for medium-voltage distribution.

Primary & Secondary Integrated RMUs are widely used in utility substations, industrial parks, commercial developments, renewable energy projects, airports, rail transit systems, and smart city power distribution networks.
