Features

a. The frame of substation is made of groove steel and angle steel which are antiseptic, so it is tough enough mechanically and rigidly.

b. Materials of the enclosure can be cold rolled steel plate, stainless steel plate, aluminum alloy plate, composite color plate.

c. The chambers of substation are divided into separate small chambers by steel plate, small chambers can be arranged in many forms such as Chinese character “eye” and ”rank”.

d. In order to monitoring and maintaining conveniently, transformer room, HV room and LV room are all equipped with lighting device.

e. The substation cover is designed as two-layer, it can prevent thermal radiation and increasing indoor temperature.

f. The transformer adopts natural ventilation mainly, when the temperature exceeds setting value, the axial flow fan on the top will start automatically to control the transformer room temperature.

g. All rotational connect parts are equipped with sealing device for good damp proof capacity.

h. Perfect protective performance, convenient operation, there are complete “five prevention” function on HV side to ensure the safety of maintenance.

i. Compact structure, beautiful appearance, it can coordinate with ambient environment.
