Cable construction RFA 1/2″-50
Structurally, RFA 1/2″-50 cable (feeder) consists of:
- center conductor: copper-plated aluminum wire with a diameter of 4,8 mm
- dielectric: foamed polyethylene with a diameter of 12,1 mm
- outer conductor: corrugated copper tube
- protective insulation: black polyethylene, halogen-free, UV-resistant
The unique feature of the RFA series cables is a double-layer protective sheath consisting of a hard HDPE skin layer and a softer LDPE skin layer. This design provides the best protection for all operating conditions without compromising the flexibility of the cable.
In addition, the dielectric foam has an extremely high degree of expansion and a special surface layer for additional protection.
