Characteristics

Electrical performance

300/500 V flame-retardant building wire with high insulation resistance, low voltage drop, and reliable performance up to 70°C.

Thermal performance

Designed for continuous operation at conductor temperatures up to 70°C, with flame-retardant PVC insulation and sheath that help resist heat and limit flame propagation during electrical faults.

Fire performance

Features flame-retardant PVC insulation and sheath that resist flame spread and help limit fire propagation, complying with IEC 60332 flame-retardant requirements.

Mechanical performance

Provides good flexibility, abrasion resistance, and mechanical strength, ensuring durability and reliable performance during installation and normal service conditions.

Environmental performance

Made with PVC materials that are recyclable and designed to reduce fire emissions (low flame spread and limited smoke), supporting safer use in indoor building environments.
