NOMEX's electrical, chemical and mechanical properties are extremely high, with excellent elasticity, flexibility, anti-tearing, moisture resistance, and wear resistance. It also provides acid and alkali corrosion protection.
Nomex has strong thermal resistance. Even if the temperature reaches 220℃, the insulation property remains unchanged — ensuring consistent performance in demanding environments.
Transformers with Nomex insulation can operate at up to 180℃ temperature rise, requiring fewer wires and ferrite cores — resulting in a smaller size, lighter weight, reduced capital construction expense, and smaller no-load loss.
With Nomex wrapped wire, electrical specifications and mechanical properties remain outstanding throughout the transformer's entire service life. It resists aging and maintains strong contraction and elasticity, ensuring no cracks develop in transformer windings. Nomex insulation is not sensitive to temperature or dust.
Nomex's high thermal resistance maintains insulation properties even at 220℃. Rank C (220℃) replaces Rank H (180℃) in transformer design, enabling the handling of urgent load situations and unexpected expansion, significantly reducing backup planning requirements.
NOMEX is chemically stable, safely flame retardant, and anti-radiation. In the event of a fire, it will not release toxic gases. It does not react with solvents and is acid and alkali corrosion resistant. After its service life, it is conveniently recyclable, the waste can be degraded, and will not cause environmental pollution. Nomex is an environmentally friendly high-tech product.
