H07RN-F AD8 Flexible Rubber Cable
The H07RN-F AD8 Flexible Rubber Cable is a heavy-duty, submersible elastomeric power and control cable rated at 450/750V (and suitable for up to 1kV in fixed, protected installations). Specifically engineered to endure weather exposure, oils, greases, mechanical stress, and thermal variations, this cable holds an AD8 water-resistant rating that allows continuous submersion in water and direct installation in buried duct systems.
What is H07RN-F AD8 Flexible Rubber Cable?
The H07RN-F AD8 Flexible Rubber Cable is a heavy-duty, submersible low-voltage (450/750V, up to 1kV fixed) multi-core and single-core power cable manufactured in strict conformity with EN 50525-2-21 and EN 60228. It is specifically engineered to combine mechanical flexibility with environmental resistance across industrial, municipal, and maritime worksites exposed to moisture, oils, and physical abrasion.
The cable features an official AD8 water-resistance classification, certifying its capability to operate under permanent water submersion and within flooded underground ducts without dielectric breakdown. Constructed with Class 5 stranded copper conductors, heat-resistant Ethylene Propylene Rubber (EPR) insulation, and an external Polychloroprene (PCP) rubber jacket, it provides resistance against oils, grease, ultraviolet radiation, and mechanical tearing, while passing vertical flame propagation standards according to IEC/EN 60332-1-2.

Frequently Asked Questions
Q: What does the AD8 rating signify on H07RN-F cables?
A: The AD8 classification certifies that the cable is rated for continuous underwater submersion under hydrostatic pressure, making it suitable for submerged pumps and permanently flooded underground utility ducts.
Q: Can H07RN-F AD8 cable be used on reeling drums?
A: Yes, it is suitable for reeling drum operations; however, derating factors must be applied based on drum configuration (e.g., 85% for ventilated radial drums, down to 35% for 4-layer cylindrical drums) to manage thermal dissipation.
Q: What mechanical and chemical protection does the PCP outer sheath offer?
A: The Polychloroprene (PCP) outer jacket provides resistance to mechanical tearing and impact while resisting degradation from lubricating oils, greases, ultraviolet solar exposure, and weathering.
Q: What commercial payment terms does Huadong Cable accept for international orders?
A: We accept standard international commercial payment terms, primarily Telegraphic Transfer (T/T, 30% advance deposit and 70% against shipping documents) and 100% Irrevocable Letter of Credit (L/C) at sight.
