Advantage of Nomex Paper-insulated Wire
It’s most suitable for the application on the coil winding from traction transformer, electrical substation, furnace transformer and various oil-filled transformer and dry type transformer.
1. Cost down, reduce the dimension and lighten the weight
Compared with traditional wire,once the dry type transformer equipped with NOMEX,the working temperature can be lifted to 150 C. The general dimension of transformer is reduced and the weight is lightened.
2. Extend workload capacity
The extra capacity will be given to correspond overload and unexpected power expansion.
3. Improve the Ability of Stability
Excellent electric and mechanical performance effects.
It’s quite elastic and with excellent aging resistance, anti-shrinkage, so the coil remains the compact structure after several years and the short-circuit impact can be undergone.
NOMEX will bring consider benefits to the customer from economic and environmental aspects,such as reduce the integrated dimension and weight.
It can improve the safety,avoid the flammability of transformer oil, increasing the capability, lower the unload loss of transformer.
