Metro systems, high-speed rail, highways, and EV charging stations — transport electrification runs on reliable power distribution. CHBEST supplies dry-type rectifier transformers for rail traction, prefabricated substations, and package transformers plus switchgear for EV charging infrastructure. All products are seismic-rated, weatherproof, and built for long-term outdoor service.
Pain Point:
Traction power requires rectifier transformers; station dual-feed supply is mandatory for safety.
Products:
Dry-type rectifier transformer, MV switchgear, LV switchgear.
Flow:
Generator → Isolated Phase Bus → Step-Up Transformer → HV Switchgear → Transmission Line.
Pain Point:
Tunnel ventilation and lighting need 24/7 uninterrupted power; service areas need EV chargers.
Products:
Prefabricated package substation, LV switchgear.
Flow:
Rural Grid / Dedicated Line → Package Substation → Tunnel Distribution Board (lighting/ventilation/fire) + Service Area EV Charger Distribution.
Pain Point:
Fast-charging stations demand high power, dedicated transformer, and multiple feeder circuits.
Products:
Package transformer (800kVA–1250kVA), GGD LV switchgear.
Flow:
10kV Connection → Package Substation → LV Switchgear → Individual Charger Circuits (with metering and protection).
