Prefabricated substations advantages
Prefabricated compact substations are suitable for residential quarters, urban public utilities and construction power supplies etc., users can select compact transformers according to different conditions of use and load levels.
Normally our customers adopt an oil filled transformer in the prefabricated compact substation if there is no special requirement because of the cheaper price than dry type transformer. The capacity of the distribution transformer is in the range of 100KVA to 1250KVA, maximum not exceeding1600KVA.
The prefabricated compact substation shell part adopts the current domestic leading technology and technology, the shell generally adopts the galvanized steel plate, the frame uses the standard container material and the production craft, has the good antiseptic performance, guarantees 20 years no rust. Equipment operation is not affected by natural climatic environment and external pollution, and it can ensure normal operation in harsh environments from -40°C to +40°C.
Prefabricated compact substation adopts the advanced designing idea, so the appearance is beautiful and the size was optimized to be 1/10 of the same capacity power substation.
