European box change

My company produces the European box voltage grade 6KV, 10kV, 24KV and 35KV. Box is mainly composed of four parts, high voltage switch cabinet, transformer, low voltage cabinet and a shell, wherein, shell material points: composite plate, stainless steel plate, composed of ordinary steel plate, galvanized plate, cement shell material. Power supply scheme with double transformer. There are a number of prominent features:
1) single channel ventilation and maintenance design.
2) switch cabinet level 10K.
3) high strength of the outer shell, cover with anti 10 wind design structure, shell rain ability.
4) coastal products can be designed anti-corrosion and anti riot design.
5) can design the air conditioning type, the interior whole decoration type pre installed substation.
6) can be used to dry transformer can also be used for oil immersed type structure.
7) stable and safe operation.
8) the product has a network of companies to prove.
