Reliable Service , 6.6 kV - 315 kVA , Oil - Immersed Transformer , Anti-lightning Impulse , Excellent Overload




1,low loss, low noise

The core laminations are composed of imported high quality grain-oriented cold-rolled silicon steel sheets with miter joints and the joints are lapped with 5 steps, thus ensuring low loss and low noise. The inside of the tank is lined with shields. Measures have also been taken for metallic structural parts located in high magnetic field, to reduce stray loss, there by the total load loss, and to relieve local overheating.


2,Safe and reliable service

Reliability of the product is the everlasting objective of Silverstone Electric and we ensure that the transformers can be operated under long service voltage and also under short time overvoltage. Appropriate cooling arrangement and relatively low current density ensure that the winding temperature rise is much lower, at least 5K, than specified in the national standard. The mechanical stress in winding conductors during short circuit is also kept well below safe limit.



3,Easy erection and maintenance

To minimize erection work at site, Silverstone Electric transformers are so fabricated that lifting the active part out of the tank for inspection after arrival at site is not mandatory. Besides, all components to be mounted on the transformer at site have been pre-assembled before dispatch, and all secondary wirings have been laid down into conduits on the transformer and connected to the terminals in the control cabinet or terminal box. Natural oil circulation and forced air cooling (ONAF ) are generally adapted in our transformers below 480MVA, and 70% nameplate rating can be achieved in case the fans are out of service. Natural oil circulation is adapted in transformers below 240MVA. Little maintenance work is required for the cooling devices.
