Quality Requirements
The paper tape should be tightly, evenly and smoothly wound on the conductor, without lack of layer, without wrinkling and cracking, the overlap of the paper tape shall not be exposed to the seam, the paper tape joint and insulation repair place allow thick insulation layer, but the length cannot be greater than 500mm.

Conductor Material
● Aluminum,the regulation in accordance with GB5584.3-85,the electric resistivity at 20C is lower than 0.02801Ω.mm/m.
● Copper,the regulation in accordance with GB5584.2-85,the electric resistivity at 20 C is lower than 0.017240.mm/m.
Advantage of Nomex Paper-insulated Wire
It's most suitable for the application of on the coil winding from mobile transformer, traction transformer, column type distribution transformer, electrical substation, furnace transformer and various oil-filled transformer and dry type transformer.
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 enhanced to 150 C, and the infrastructure cost can be lower due to less requirement of conductor and magnetic core.The general dimension of transformer is reduced and the weight is lightened due to needless to install the vault and oil tank.In addition,the unload loss of transformer will be downsized to the minimum due to less magnetic core and be easy installed as well.
Increasing extended workload capacity
The extra capacity will be given could correspond overload and unexpected power expansion,thus,the additional procurement can be reduced.
Improved Stability
Outstanding electric and mechanical performance effects during the whole duration of usage.
It's quite elastic and with excellent aging resistance,anti-shrinkage,therefore,the coil remains the compact structure after several years and the short-circuit impact can be undergone.
It's summarized that NOMEX will bring consider benefits to the customer from economic and environmental aspects,such as 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.
