FEATURES
- 99.97% pure bright annealed copper for low conductor resistance.
- Insulated with in-house manufactured, high-grade PVC compound for superior insulation resistance.
- Offers excellent mechanical strength and electrical performance.
- Features sequential meter marking for easy length tracking and usage.
INSULATION TYPE
HFFR-CLASS 5- Halogen Free Flame Retardant (HFFR) insulation designed to withstand temperatures up to 85°C.
- High insulation resistance ensures enhanced electrical safety and reliability.
- Enables higher current-carrying capacity for improved performance.
- Delivers superior electrical and mechanical performance at elevated temperatures.
- The bunch conductors are insulated with specially formulated grade of halogen free flame retardant (HFFR) compound is used.
- The insulation does not melt or drop in case of fire. The smoke emitted is transparent, non-toxic and minimal.
