China Paper Covered Copper Wire Manufacturers, Factory

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.

Product Description

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.

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.

Increasing extended workload capacity

The extra capacity will be given could correspond overload and unexpected power expansion, thus, the additional procurement can be reduced.

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.

Summary of Benefits

NOMEX can bring considerable benefits to the customer from economic and environmental aspects. It can reduce the integrated dimension and weight, improve the safety, avoid the flammability of transformer oil, increase the capability, and lower the unload loss of transformer.

Frequently Asked Questions

Where is Nomex paper-insulated wire commonly used?

It is suitable for coil windings in various electrical equipment, including mobile transformers, traction transformers, column distribution transformers, furnace transformers, and dry-type transformers.

How does it help in reducing transformer dimensions and weight?

By using NOMEX, the working temperature of dry-type transformers can be increased up to 150 °C. This thermal capability allows for smaller transformer dimensions, lighter weight, and reduced core magnetic requirements, which minimizes unload loss.

Can Nomex-insulated wire handle unexpected power demands?

Yes. It increases the extended workload capacity of transformers, helping them withstand overload conditions and unexpected power expansions. This reduces the necessity of purchasing additional equipment.

What makes Nomex paper-insulated wire highly stable?

It features exceptional electrical properties and mechanical performance. Because it is elastic, age-resistant, and anti-shrinkage, the coil maintains a highly compact structure over years of operation, resisting short-circuit impacts.

What are the environmental and safety advantages of NOMEX?

NOMEX improves safety by eliminating the flammability risk associated with transformer oil. Additionally, it optimizes efficiency by lowering unload loss and reduces raw material footprint through downsized dimensions.
