Three Phase Electrical Pad Mounted Step Down Oil Immersed
Transformer 1000kva 15kv
summary
The three phase pad mounted transformers we produce have obtained
UL certification, with capacities ranging from 30 to 5500kVA and
voltages up to 34.5kV. Our products are exported to North America
the Philippines and other places in large quantities.
Product Structure
Performance
1) The structure is compact and reasonable, and the volume is
small, which is only about one-third of the European-style box
change of the same capacity;
2) Fully sealed, fully insulated structure, no need to set up
safety barriers, and reliable guarantee for personal safety;
3) There are a variety of power supply schemes for users to choose
from, which can adopt terminal power supply and realize ring
network or dual power supply;
4) S11 oil-immersed power transformer is adopted, which has low
loss, low temperature rise and strong overload capacity;
5) Double fuses (backup protection fuse + plug-in fuse) are used
for protection, and the plug-in fuse fuse has the current and
temperature dual sensitivity characteristics to ensure the safe and
reliable operation of the product;
