Power Extension Cable Kerg H05RRF 3G1.5 50m black rubber EPR

Kerg power extension cable H05RRF 3G1.5, 50 m in black rubber EPR is a flexible, rubber-sheathed mains cable intended for power distribution in temporary and permanent installations. The cable has three conductors with a cross-section of 1.5 mm², insulated and sheathed in EPR rubber to provide mechanical resilience and basic resistance to oils and abrasion. Its 50 m length allows reliable connection of electrical equipment over extended distances on construction sites, in workshops and outdoor setups where a durable rubber cable is needed.

Advantages

The rubber EPR sheath provides flexible handling and improved durability compared with plain PVC-sheathed cords, while the 3G1.5 conductor configuration supports standard single-phase loads and lighting circuits. The 50 m length reduces the need for multiple joins and additional extension points. The cable is suitable for repeated handling and temporary outdoor use thanks to its flexible core and robust external sheath.

Suitable for

• Temporary power distribution on construction and renovation sites
• Connecting power tools and workshop equipment
• Outdoor event power where flexible rubber-sheathed cable is required
• Long-distance routing for lighting circuits and small appliances

Key specifications

• Conductor configuration: 3 cores (live, neutral, earth)
• Conductor cross-section: 1.5 mm² per core
• Length: 50 m
• Insulation and sheath material: EPR rubber (ethylene propylene rubber)
• Colour: black
• Construction: flexible stranded conductors with rubber insulation

How to use

Install and route the cable so it is not subjected to sharp edges, excessive tensile forces or prolonged exposure to chemicals beyond EPR’s resistance. Use appropriate plugs, sockets or connectors rated for the intended current and environment; ensure protective devices (RCDs, fuses or circuit breakers) are installed in the supply circuit. Avoid permanent burial of the cable unless it is specifically approved for such use; inspect the sheath and conductors regularly and replace the cable if visible damage or degradation is found.

Usage recommendations

For safe operation, match the cable to the device’s current draw and the circuit protection rating. Do not exceed the permissible current for 1.5 mm² conductors; minimise jointing and avoid using the cable where temperatures or chemical exposure exceed EPR specifications. Store the cable coiled without sharp bends and protect from prolonged UV exposure when used outdoors.
