cast resin dry type transformer,
dry cast resin transformers
1. Safe, fireproof, no pollution, it can be installed directly in the load center.
2.Free maintenance, easy to install, low total operating costs.
3. With good moisture resistance, it can work normally under the100% humidity. After it stopped operating, the outage without pre-drying can be put into operation again.
4. Low loss, low partial discharge, low noise, good heat dissipation capacity. Under the forced air cooling conditions, it can run at 150% rated load.
5. The equipped perfect humidity protection & control system can provide reliable
Adopting the entire section of copper foil, together with the F-class turn insulation, low voltage winding is wound by the special low-voltage foil winding machine. The foil coil resolves such understanding problems as large short-circuit stress, uneven ampere turn, poor heat dissipation, existing the winding spiral angle as well as unsteady manual welding quality due to low voltage and large current coil winding products. At the same time, the winding end in our company is treated with resin potting, solidification to make shape, moisture-proof and anti-fouling, the lead copper platoon is automatically welded by argon arc welding.
Temperature Control Device:
the transformer adopts BWDK series of signal thermometer. The temperature components, are embedded in the upper half of the low-voltage coil, can automatically detect and dynamically display the work humidity of phase coils and also have the functions of over-temperature alarm and trip.
Low loss:the product no-load loss is 20% lower than the Sc (B) 11 type product with an
excellent energysaving effect, economic efficient operation and without maintenance.
Low noise:the product noise level is 10-15 db lower than the existing professional standard
JB/T10088- 2004Sound Level of 6- -220KV Transformer
Low partial discharge:resin mixture adopts foreign leading-edge mixing method and film type
vacuumdeaerator to evenly mix the mixture and remove the bubble in the bottom part of mixture.
The product hasa low partial discharge which can be controlled at 5PC. Both high voltage and low
voltage coils can bepoured in vacuum pressure so as to enable a encapsulating of resin insulation
and immersion amonglayers and inter-tums. The poured part has a compact solidity staicture with
anti-flaming, anti explosionand environmental protection features.
Glass fiber and other raw materials of winding coil have self- extinguishing property and will not
producearc due to short circuit. Resin will not produce harmful gas under high temperature.
