NOMEX paper covered wire is made of oxygen-free copper rod or electrical round aluminum rod extruded by a certain specification of the wire, and then produced by the United States DuPont T410 NOMEX insulating paper winding from winding the winding line, mainly for transformers, Winding of welding machines, electromagnets or other similar electrical equipment. The bare copper (aluminum) conductor produced by the extrusion process is the ideal material for the production of NOMEX paper covered wire.

The advantages of Nomex paper covered wire:
Because of its electrical, chemical and mechanical integrity, and its elasticity, flexibility, tear resistance, moisture resistance and abrasion resistance, NOMEX paper is extremely resistant to acids and bases and is insensitive to insects, molds and fungi It can be compatible with all kinds of varnishes, adhesives, transformer fluids, lubricants and refrigerants. NOMEX paper also has high heat resistance and maintains the original insulation performance even at temperatures up to 220 ° C. Use NOMEX paper bags Line transformers can bring customers a lot of economic, environmental and safety benefits.
Reduce costs, reduce size, reduce weight
NOMEX products insulated transformer, the temperature can be designed to 180 ℃, requires less wire and iron core, can be reduced size, reduce weight, thereby reducing the capital costs, easy to install, also means that the smaller iron core load loss small
Transformer windings use NOMEX paper covered wire to maintain excellent electrical and mechanical properties throughout the life of the transformer. NOMEX paper is resistant to shrinkage and compression, is resilient and should not be aged, withstands thermal shock and therefore ensures transformer coil construction Tight, does not produce cracks, the other NOMEX insulation paper is not sensitive to temperature, dust, improve transformer reliability.
Increase backup capacity
NOMEX paper heat-resistant high temperature, even at temperatures up to 220 ℃, still maintain the original insulation performance. Transformer design class C 220 ℃ insulation material as Class H 180 ℃ use, can meet the emergency overload load and unexpected expansion, so that the backup plan can be greatly reduced.
Good environmental performance
NOMEX insulation chemical stability, safety flame retardant, non-toxic, anti-radiation, even in the event of a fire will not release toxic gases; and solvent does not reflect the acid and alkali corrosion. When the end of its service life, convenient recycling, reusable resources, waste can be degraded, will not cause environmental pollution, is an environmentally friendly high-tech products.
