Paper Covered Flat Copper Wire

Short Description:

1.This is a very durable and reliable wire that is very suitable for various applications. The wires are made of oxygen free copper rods or circular aluminum rods, and are extruded or stretched through specific specifications of molds. Then wrap the wires with specific insulation materials to ensure the highest quality performance and service life

2.Paper wrapped wires are a multifunctional product that can be used in many applications that require high conductivity and durable wires. Composite wires are made by arranging multiple winding wires or copper aluminum wires based on specific insulation materials according to specific requirements. The resulting wires are very durable and can withstand high temperatures and environmental conditions, making them an ideal choice for various industrial applications

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.

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 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.

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. 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.
