NOMEX's electrical, chemical and mechanical properties are extremely high, with excellent elasticity, flexibility, anti-tearing, moisture resistance and wear resistance. It also resists acid and alkali corrosion and is not easily destroyed by insects, molds and fungi.
Nomex maintains its insulation property even at temperatures reaching 220℃. Transformers with Nomex wrapped wire deliver economic, environmental and security benefits to clients.
Temperature can rise up to 180℃, requiring fewer wires and ferrite cores — resulting in smaller size and lighter weight. Capital construction expense is reduced, installation is easier, and smaller ferrite cores mean smaller no-load loss.
Nomex wrapped wire delivers outstanding electrical and mechanical performance throughout the transformer's entire service life. It resists aging and maintains strong contraction and elasticity — ensuring transformer windings stay close with no cracking. Nomex insulation is not sensitive to temperature or dust, improving overall transformer reliability.
Nomex's high thermal resistance means insulation properties remain stable at 220℃. Rank C (220℃) replaces Rank H (180℃) in transformer design, allowing it to handle urgent load situations and unexpected capacity expansion — greatly reducing the need for backup planning.
NOMEX is chemically stable, safely flame retardant, and anti-radiation. Even in a fire, it will not release toxic gases. It does not react with solvents and resists acid and alkali corrosion. At end-of-life, it is conveniently recyclable — waste can be degraded without causing environmental pollution. Nomex is a truly environmentally friendly high-tech product.
