Wholesale Paper Covered Aluminum Wire Supplier, Factory

Paper-covered wire is a winding wire made of bare copper round rod, bare copper flat wire and enamelled flat wire wrapped by specific insulating materials.

The combined wire is a winding wire which is arranged in accordance with the specified requirements and wrapped by a specific insulating material.

Paper-covered wire and combined wire are important raw materials for manufacturing transformer windings.

It is mainly used in the winding of oil-immersed transformer and reactor.

Product Description

Advantage of Nomex Paper-insulated Wire

It's most suitable for the application on the coil winding from traction 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 lifted to 150 °C.

The general dimension of transformer is reduced and the weight is lightened.

Extend workload capacity

The extra capacity will be given to correspond overload and unexpected power expansion.

Improve the Ability of Stability

Excellent electric and mechanical performance effects.

It's quite elastic and with excellent aging resistance, anti-shrinkage, so the coil remains the compact structure after several years and the short-circuit impact can be undergone.

NOMEX will bring consider benefits to the customer from economic and environmental aspects, such as reduce the integrated dimension and weight.

It can improve the safety, avoid the flammability of transformer oil, increasing the capability, lower the unload loss of transformer.

Frequently Asked Questions

Q: Where is Nomex paper-insulated wire most suitable for use?

It is ideal for coil windings in traction transformers, electrical substations, furnace transformers, and various oil-filled and dry-type transformers.

Q: How does Nomex paper-insulated wire help reduce costs and weight?

By using Nomex, the transformer's working temperature can be raised to 150 °C, which reduces the overall dimension and lightens the total weight of the system.

Q: Can Nomex insulated wire handle unexpected power overloads?

Yes, it effectively extends workload capacity, providing extra buffer to handle overloads and unexpected power expansions.

Q: How does this wire ensure long-term mechanical stability?

The insulation is highly elastic with excellent resistance to aging and shrinkage. This allows the coil to maintain a compact structure over many years and survive short-circuit impacts.

Q: What are the safety and environmental benefits of Nomex insulation?

It improves safety by avoiding the flammability risk of transformer oil, increases overall capability, and reduces the no-load loss of the transformer.
