Product Classification:

1.Power transformers are classified by use: boost (power plant 6.3kv / 10.5kv or 10.5kv /110kV, etc.), contact (220kV/110kV or 110kV/ 10.5kv between substations), voltage reduction (distribution 35kV/ 0.4kv or 10.5kv / 0.4kv).
2.Power transformers are classified by phase number: single phase, three phase.

3.Power transformers are classified by insulation media: oil-immersed transformers (flame retardant, non-flame retardant), dry transformers, 110kVSF6 gas insulated transformers.

Dry type transformer

Performance characteristics:

1.The low-voltage windings of oil-immersed transformer are usually wrapped in copper foil, except for copper conductor.

The high voltage winding adopts multi-layer cylindrical structure to balance the ampere-turns distribution of the winding, the leakage is small, the mechanical strength is high, and the anti-short circuit capability is strong.

2.Iron core and winding each adopt the fastening measure, the height of the device, the low voltage lead and so on fastening parts all take the lock to prevent the nut, the use of the non-lifting structure, can withstand the transportation of the shock.

3.Coil and iron core adopt vacuum drying, the transformer oil adopts vacuum filter oil and oil filling process, which minimizes the moisture in the transformer.
