Specializing in the development and production of 35kv, 24kv, 10kv, 0. 4kv high and low voltage switchgear, outdoor box-type substations, DC power supply devices, power transformers, automatic control devices and circuit breakers and other productsThere are numerous types of switchgear sets, categorized primarily based on four key dimensions: voltage level, insulation medium, installation environment, and primary structural form. First, by voltage level, they can be divided into low-voltage sets (such as low-voltage distribution panels) and. It is used for motor centralized control and capacitance compensation of power and distribution in power generation and supply system of three-phase AC 50Hz, rated working voltage 400V (690V), rated current 4000A or less.
