Functions and Features


High-voltage switchgear, distribution transformers, low-voltage switchgear, electric energy metering equipment and reactive power compensation devices are combined according to a certain plan, and the complete set is strong.
● Perfect high and low voltage protection, safe and reliable operation, and simple maintenance.
Small footprint, low investment, short production cycle, and easy to move.
● Flexible and diverse wiring schemes;
Unique structure: unique honeycomb structure double-layer (composite plate) shell is firm, heat insulation and heat dissipation ventilation, beautiful, high protection level, shell materials are stainless steel titanium alloy, aluminum alloy, cold-rolled plate, color steel plate optional;
● Variety of types: universal, special, compact, and other styles;
● The automatic end point (FTU) of the distribution network can be installed in the high-voltage ring network cabinet to realize the reliable detection of short circuit and single-phase ground fault, and has the function of "four remote", which is convenient for the automatic upgrade of the distribution network.
