Advantage of NOMEX Paper Wrapped Wire

NOMEX paper covered wire’s electrical, chemical and mechanical properties are extremely high, and it’s elasticity, flexibility, anti-tearing, moisture resistance and resistance to wear are very good. Moreover it has the acid and alkali corrosion. And it is not easily destroyed by insects, fungus as well as streptomyces. It has the compatibility with all kinds of varnish, adhesive, transformer liquid, lubricant, and coolant. Meanwhile, NOMEX paper has strong thermal resistance. Even if the temperature reaches 220℃, the insulation property is the same. Transformer with NOMEX paper wrapper wire can bring client a lot of economic, environmental and safe benefits.

Lower Cost, smaller Size, Lighter Weight

The temperature of transformer with NOMEX insulation can rise up to 180℃. Because the transformer needs fewer wires and ferrite cores and then it has smaller size and lighter weight, thus capital construction can be reduced. It is easy to install the transformer. Smaller ferrite core means reducing no-load loss.

Reliability Improvement

With NOMEX paper wrapped wire, the electrical specification and the mechanical property are outstanding in the transformer’s entire service life. NOMEX paper and there is no crack. NOMEX insulation paper is not sensitive to temperature, dust and thus improve the reliability of transformer.

Increase of Reserve Capacity

NOMEX paper covered wire’s thermal resistance is high, so even though the temperature reaches 220℃, the insulation property maintains the same. Rank C of 220℃ takes the place of Rank of 180℃during the design of transformer, so it may deal with the urgent load situation and the dilatancy unexpectedly and can make backup plan.

wholesale paper wire

The paper covered wireis the wire that oxygen-free copper rod or electric round aluminum rod with certain specification moldex truded or drawn from specific insulation material wrapped winding wire. Composite conductor according to requirements by the number of root winding wire or copper, aluminum wire is arranged by the specific insulating material around the package from the winding wire.

The paper covered wire is mainly used for winding oil-immersed transformers, reactors and other electrical devices.

Zhengzhou LP Industry Co., Ltd can provide high-quality paper covered wire with competitive price.

NOMEX Paper Covered Wire

NOMEX Paper Covered Wire is a kind of electric wire wrapping with NOMEX insulated paper from America DuPont .NOMEX insulating paper has good electrical, high chemical and mechanical integrity and its elasticity , flexibility, tear resistance , moisture resistance and abrasion resistance are very good. Because of its acid corrosion, it can be compatible with all kinds of varnish, sticky compatible mixture , transformer fluids, lubricating oils and refrigerants . Because NOMEX product is not easily digested , it will not be damaged by insects, fungi and molds . NOMEX products’ mechanical properties were not affected at a temperature no higher than 200 ℃. The product can maintain at least 10 years long, even if the continuous violence placed 220 ℃ high temperature.

NOMEX paper covered wire uses the bare extrusion aluminum as the conductor. It has better electrical properties and better mechanical properties , so it can replace the difficulty of making large enameled flat wire for transformers, lifting electromagnet , welding and other products windings.

NOMEX Paper CoveredWire is applicable to mobile transformers, traction transformers, pole-mounted distribution transformers, power substations, rectifiers, electric transformers and other oil-immersed transformer coil windings. Oil-immersed transformers using NOMEX wrapped magnet wire can bring many economic, environmental and safety benefits that can reduce weight, reduce the volume, reduce transformer oil, improve safety, reduce flammability of transformers, increase the capacity and reduce energy loss and so on.
