How to Verify RG7H1R / RG7OZR Cable Quality
- Standard compliance: IEC 60502-2 on datasheet and cable marking
- Partial discharge test: ≤5 pC at 1.73× U0 (type test certificate)
- Impulse voltage test: BIL per IEC 60502-2 for voltage rating
- Conductor screen: Semiconducting layer extruded over conductor
- Insulation: EPR (ethylene propylene rubber) — 90°C rated
- Metallic screen: Copper wire or tape, minimum 90% coverage
- Armour (RG7OZR): Galvanized steel wire armour for mechanical protection
- Cable marking: Type, voltage, manufacturer, standard on sheath
Common Substitution Scenarios
- Replacing BS 6622 with RG7OZR: RG7OZR is IEC 60502-2 compliant — generally compatible. Verify voltage rating and construction.
- Replacing NA2XY/N2XY with RG7H1R/RG7OZR: Direct IEC equivalent. Verify dimensions match existing terminations.
- Replacing IEEE 383 with RG7OZR: Possible for international projects. Test methods differ but EPR performance is comparable.
- Upgrading from RG7H1R to RG7OZR: Same core construction — adds armour for direct burial where mechanical protection is now required.
