General :
ZGSll combined transformer is absorbed in American-style transformer on the basis of self-developed high-tech products. Also known as the American box changed. Capacity range of 200-1000kVA, suitable for 10kV distribution network neutral point insulated system or via low resistance grounding system, and 400V three-phase four-wire system is directly grounded neutral point system. Complete and strong, reliable power, small size, light weight, low noise: a ring-type cable outlet and the terminal. This product enables the use of 10kV power grid in-depth load center, to reduce line losses, improve reliability and beautify the urban environment for network reform. |
Feature :
The product with the "9" transformer load loss reduction compared to 30.12%, an average annual operating costs 20.03%. Low noise, for environmentally friendly products.
The body of the transformer, high voltage load switch (load switch or high pressure), fuse, no circuit tap, and all placed within a sealed tank, improved space utilization. Its volume is only about the same voltage level, combined with substation capacity (also known as Europe change) 1 / 3 the weight has been greatly reduced.
High and low pressure isolation room, take interlock. When the low pressure chamber to open the door to open only after the high pressure chamber door, fully insulated high-voltage terminal, security is good.
Use two fuses (back-up current-limiting fuses, plug-in fuse) a combination of full range of protection, safe, reliable, flexible, easy fuse replacement.
Tank for the whole sealed structure, the oil tank and isolated. No leakage, maintenance-free.
