Specifications

Our company provide 330kV oil-immersed power transformer ,with capacity of 360MVA and below. 1)Low loss,

1)low partial discharge

2)high short circuit withstand capability series transformers are achieved through innovation and optimization.

3)Our transformer conform entirely with latest national standard GB1094.1~2-1996, GB1094.3-2003, GB1094.5-2003 and international standard IEC-76.

Transformer Outstanding features as follows:

1. Low loss, low noise

The core laminations are composed of imported high quality grain-oriented cold-rolled silicon steel sheets with chamfered joints and the joints are step-lapped with 5 steps, thus ensuring low loss and low noise. The inside of the tank is lined with magnetic and copper shields, measures have been take for metallic structural pares located in high magnetic field, to deduce stray loss and thereby the total load loss, and to relieve local overhearing.

2. Safe and reliable service

Reliability is the everlasting objective of our company, partial discharge of finished products are constantly kept below 100pC, ensuring that the transformers can be operated under long service voltage and occasional over-voltage without trouble.

3. Easy erection and maintenance

To minimize erection work at sit, transformers are so fabricated that lifting the active part out of the tank for inspection after arrival at sit is not mandatory. Beside, all components to be mounted on the transformer at site have been preassembled 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 180kV class transformers below 240MVA. 70% nameplate rating can still be achieved in case the fans are out of service. Little maintenance work is required for the cooling devices.
