Iron Galvanized Combined Substation/ 12KV prefabricated subststion
Model No.: ZBW1-12
1. The frame of Substation is made of steel and angle iron galvanized to have the enough mechanical strength.
2. Cold-rolled steel sheet, stainless steel, aluminum alloy sheet or compound colorful sheet is used for the enclosure.
3. Each cubicle is separated by steel sheet to be different shape inside.
4. The illuminating devices are installed inside L. V. &H. V. Cubicles and transformer cubicle for supervision and maintenance.
5. The cover is double-layer to prevent the heat from increasing temperature.
6. Natural ventilation is taken for transformer. When the temperature inside the transformer cubicle is higher than the set temperature, the fan installed on the top will start to work and control the temperature.
7. Sealing devices are put on the turning parts to be moisture-proof.
8. Perfect protection and convenient operation, particularly "five-proof"functions on H. V. Side ensures the security of maintenance.
9. The product is good-looking and natural in certain environment.
