The European box-type transformer substation with small dimension and beautiful appearance is more and more popular. This device can achieve the goal of automatic protection and computer remote control with unattended operation during service in network. So European box-type transformer is widely used in any site such as residential area, business center, transportation junction and industrial park.

(1)Advanced technology: It has a high mechanical strength for its skeleton welded by high quality steel channel and steel angels; it also has a excellent anticorrosion performance for its shell is made by aluminium alloy, after printing, it can be integrated with around environment.

(2)High automation level: the HV chamber, transformer chamber and LV chamber are independent respectively in box-type substation. The device in HV chamber is HV ring-network switch device which can adopt compressed-gas type, gas-producing type or vacuum-load switch. The transformer adopting natural air and auto-control forced-air cooling device is equipped with heat-extraction system auto-controlled as temperature rise which can control temperature in box and meet operation requirement. The LV chamber has the general functions of LV switch that can be selected by uses.

(3)The cost will be less 40％ -50％ than general substation with same scale. Prefabrication service and installation for 5~8 days, and its appearance can be integrated with around environment.

HV incoming cabinet, HV gauge cabinet (selected by uses), HV ring-network cabinet (ring-network type box-transformer substation) and HV outgoing cabinet. In box-type substation, we can installed various types of oil-immersed transformer and dry-type transformer. We can produce any types of oil-immersed or dry-type transformer, and can also produce some transformers with special requirements according to users’requirements.
