Product Introduction

YB-12 Outdoor box-type substation is realized by cables or busbars. All high and low voltage power distribution devices and transformers are conventional stereotyped products. substation” or “prefabricated substation”.
Our YB-12 Outdoor box-type substation is a trinity of high-voltage switchgear, transformer, and low-voltage switchgear, with strong completeness; perfect high and low voltage protection, safe and reliable operation, and simple maintenance; less land occupation, less investment, short production cycle, and convenient movement; flexible and diverse wiring schemes; unique structure : Unique honeycomb structure double-layer (composite plate) shell is firm, heat insulation, heat dissipation and ventilation, beautiful, high protection level, shell materials are stainless steel alloy, aluminum alloy, cold-rolled plate, color steel plate optional; various types: universal type , villa type, compact type and other styles; the high-voltage ring network cabinet can be equipped with network automation terminals (to achieve reliable detection of short-circuit and single-phase ground faults, with "four remote" functions, which is convenient for distribution network automation upgrades.
