NOMEX's electrical, chemical and mechanical properties are extremely high, with excellent elasticity, flexibility, anti-tearing, moisture resistance and wear resistance. Moreover, it has acid and alkali corrosion resistance and is not easily destroyed by insects, molds and fungi. It has compatibility with all kinds of varnish, adhesive, transformer liquid, lubricant and coolant.
Nomex has strong thermal resistance. Even if the temperature reaches 220℃, the insulation property remains the same. Transformer with Nomex wrapped wire can bring clients a lot of economic, environmental and security benefits.
The temperature of transformer with Nomex insulation can rise up to 180℃ because the transformer needs fewer wires and ferrite cores, resulting in smaller size and lighter weight. This reduces capital construction expense, makes installation easier, and a smaller ferrite core means smaller no-load loss.
With Nomex wrapped wire, the electrical specification and mechanical property are outstanding throughout the transformer's entire service life. Nomex wrapping magnet wire is not easy to age and has strong contraction and elasticity, ensuring the transformer winding maintains close contact with no cracks. Nomex insulation paper is not sensitive to temperature or dust, thus improving the reliability of transformers.
Nomex's thermal resistance is high, so even though the temperature reaches 220℃, the insulation property remains the same. Rank C of 220℃ takes the place of Rank H of 180℃ during transformer design, allowing it to handle urgent load situations and unexpected expansion, greatly reducing the need for backup plans.
NOMEX is chemically stable, safety flame retardant, and anti-radiation. Even in the event of a fire, it will not release toxic gases. It does not react with solvents and resists acid and alkali corrosion. After the end of its service life, it is conveniently recyclable, and the waste can be degraded without causing environmental pollution. Nomex is an environmentally friendly high-tech product.
