       This series of combined substations are 35kV on the high voltage side, 10kV, 6kV and 0.4kV on the low voltage side, three-phase AC 50Hz outdoor complete equipment, generally suitable for some large construction sites, as the reception, conversion and distribution of electrical energy, is an economical, affordable, easy to flow transportation and fixed installation of new substations.

The 35kV box-type substation produced by our company adopts China's advanced electrical equipment and technology, and realizes oil-free and "four remote" functions in the box to reach the condition of no one on duty. The container substation has the characteristics of less occupation of land, less investment, short construction period, simple installation and debugging, safety and reliability, etc.
The double-deck box shell by Luxembourg import aluminium zinc steel plate, anti-corrosion 20 years, the inner layer for choi steel gusset plate, fire prevention, insulation materials, filled with middle guarantee body sealing, thermal insulation, than other box-type substation is more durable, long preservation period, the characteristics of warm in winter and cool in summer, can make the box in the harsh environment under normal operation; If the substation increases capacity or increases the output line, then a switch box can be realized, and also can be connected with the first phase of the box body as a whole. Switch cabinet with automatic temperature adjustment, automatic ventilation, good weather, dust pollution, enclosure structure is compact, cover an area of an area small, investment province, cycle short, transferable, less waste, less complete, convenient in installation, can be configured in the comprehensive automatic equipment, image monitoring equipment, can be arbitrary configuration of various communications equipment. High reliability in use.
