Compact structure, small size, less land, convenient transportation, convenient shape, in the form of a box becomes \"目 \" word, \"product \" word.

The outer casing has the characteristics of rugged, insulation, dust, moisture-proof, anti-small animals. The outer casing can be made of aluminum-zinc plate, ordinary steel plate, stainless steel plate, color steel plate, environmentally friendly non-metallic (GRC) material, etc. Has strong mechanical properties, resistance resistance, and anti-corrosion performance. The appearance color and pattern can be customized according to customer needs, making it better with surrounding buildings.

The maze plate structure is used, not only beautiful, easy to disassemble, and has good ventilation fan heat performance. Perfect protection performance, easy to operate, can measure high, low voltage side

The transformer unit can be used to fully seal the oil immersion transformer, etc., and SCB and SGB dry transformers can also be employed.

High-voltage cabinets can use gas insulation ring network cabinets, solid insulated ring network cabinets to meet different site and climatic conditions
