NOMEX Paper Covered Winding Wire
Product introductionHeg
NOMEX coated Aluminum wire produced has flat and round.
NOMEX covering corresponds to class H insulation is mainly used in the construction of condensers and capacitors. Main application of it is in shielding of cables in high temp. environment (200°C) such as dry type transformers, military and aerospace cables. NOMEX covered conductors are more effective in condition where temperature resistance and dielectric strength requirements are high.
By extrusion of bare aluminum wire wrapped and NOMEX Paper covered wire, the mechanical performance and electrical performance better, instead of making difficult composite enameled flat wire, suitable for transformer, winding of lifting electromagnet, electric welding machine and other products.

Advantage of NOMEX Paper Wrapped WireHeg
NOMEX paper'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'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.
