Paper Covered Copper Wire

Short Description:

This paper covered wire is made with high-quality oxygen-free copper rod or electrician round aluminum rod that has been extruded or drawn by a specialized mold to ensure the utmost in precision and consistency. The winding wire is then wrapped with a specific insulating material that is chosen for its exceptional durability and reliability.

The DC resistance of paper covered round copper wire should comply with regulations. After the paper covered round wire is wound, the paper insulation should have no crack, seams or obvious warping. It has a superior surface area for conducting electricity, which allows it to deliver fast and efficient performance even in demanding applications.

In addition to its outstanding electrical properties, this paper covered wire also offers exceptional durability and resistance to wear and tear. This makes it an excellent choice for use in harsh environments where other types of wire may quickly break down or become damaged.

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.
