IGBT dual-tuble module cabinet, eliminating the current-limiting inductor of thyristor inverter, widely save the consumption of power. The energy consumption will be cut over 5% compared with the thyristor cabinet.

IGBT dual-tuble module cabinet is stable and reliable by adding protection device. One driver board drives one modular. The reliability is highly enhanced. Even there is a short circuit in the load end, sparking, steel bleeding-out, water cooling cable burning, it will not damage the cabinet. This also solves the problem of single-tube IGBT device bleaking one after another. It cut the maintenance cost greatly.

On practicality, IGBT dual-tube module cabinet is quiet,durable, strong overloading capacity. It need not special using environment. Using and maintain is easy.
