Product Details
Advantage of Nomex Paper-insulated Wire
It fits for application on the coil windings of mobile transformers, traction transformers, column distribution transformers, furnace transformers, and dry type transformers.
1. Cost down,reduce the dimension and lighten the weight
Compared to traditional wire,once the dry type transformer equipped with NOMEX,the working temperature can be lifted to 150 C. It can reduce the general dimension of transformer and lighten the weight. The unload loss of transformer will be downsized to the minimum due to less magnetic core.
2. Increasing extended workload capacity
The extra capacity will be given could correspond overload and unexpected power expansion,thus, the additional procurement can be reduced.
3. Improve the Ability of Stability
Outstanding electric ability and mechanical performance effects during usage.
It’s elastic with excellent aging resistance, anti-shrinkage,therefore,the coil remains the compact structure after using several years and
the short-circuit impact will be undergone.
To summarize, NOMEX can bring consider benefits to the customer from economic and environmental aspects.
NOMEX can reduce the integrated dimension and weight,improve the safety,avoid the flammability of transformer oil,increasing the capability,lower the unload loss of transformer,and etc.
