66 -110kV Oil Immersed Type Power Transformer

General
The design and technology of 110KV Transformer in Tianan(group) are coming by summarizing and re-exploitation based on multifold and advanced technique. We combined the transformer production and design experiences in our company, the reliability and performance standard are all achieved international advanced level. By the way of constantly summarizing and making perfect, the product have been formed a series production which have the Tianan characteristic, it possesses: low losses 、low noise、low partial discharge、strong anti-short-circuit ability、high impedance and fully sealed, we also take special leakage-proof measures. The characteristic of these transformers can be concluded as follows.

Standard:
IEC, ANSI, IEEE, GOST, GB etc.

product details

Product Features

● Low loss

◆ Electrical calculation by sophisticated computer programs, combine electrical shielding and magnetic circuit technology.

◆ The core is made of cold rolled, grain orientation high magnetic silicon steel, to reduce the load loss and no-load current.

● Low partial discharge

◆ HV lead adopts specially molded insulation parts which effectively ensure the insulation strength and reduces partial discharge.

● High strength

◆ The tank can withstand the vacuum test and positive pressure test.

◆ Omni directional location between the core and the tank to guarantee the horizontal position during transportation and operation.

● Low Noise

◆ The step lapped joints of the core laminations reduce the additional losses arising in the corner portions, reduce the load current and electromagnetic noise.

◆ Reduce of the flux density and increase the shock absorbing measures at design to reduce the noise.

● Maintenance-free

◆ Adopts the bell type tank and the international leading technology, ensure 30 years durability，and maintenance-free operation.
