RG7H1R 3.6/6kV Airport Lighting Primary Cable
TEBAOFLEX RG7H1R is a medium-voltage primary cable for airfield lighting series circuits. It connects constant-current regulators with isolating transformers in airport ground-lighting installations, where dependable electrical performance, clear circuit identification and mechanical durability are essential.
The cable uses a compact stranded bare copper conductor, G7-type rubber insulation, semi-conductive layers and a red PVC sheath. Before specification, confirm the circuit voltage, installation route, conductor size and local project requirements.
Key Features
- Airport lighting application: designed for primary series circuits between constant-current regulators and isolating transformers.
- Medium-voltage construction: 3.6/6 kV rating for airfield ground-lighting cable systems.
- Screened design: semi-conductive layers and bare copper tape shielding support the specified construction.
- Red PVC sheath: provides clear visual identification for airport-lighting circuit routing.
