Power extension cable Kerg model W2428 H05RRF 3G2.5 20m black rubber EPR fixed sockets

Kerg W2428 is a 20‑metre power extension cable with H05RRF flexible rubber (EPR) insulation and a 3G2.5 mm² conductor configuration fitted with fixed sockets. It is designed to extend mains power for electric tools, appliances and temporary installations where a robust outer sheath and flexible handling are required. The rubber EPR jacket provides enhanced mechanical protection and resistance to abrasion, making the cable suitable for workshop and outdoor environments where increased durability is important.

Advantages

The rubber-insulated H05RRF construction delivers high flexibility at low temperatures and improved resistance to oils and mechanical wear compared with standard PVC-sheathed leads. The 3G2.5 mm² conductors support typical domestic and light-professional loads while keeping voltage drop small across the 20 m length. Fixed sockets ensure secure connections and simplify repeated use with handheld tools and portable equipment. The black rubber finish resists dirt and is easier to maintain in heavy-use locations.

Suitable for

• Extending mains power to electric power tools on construction sites and in workshops
• Temporary power supply for outdoor events, markets and maintenance work
• Powering domestic appliances at a distance from fixed sockets
• Workshop equipment and portable machines requiring flexible, durable cabling

Key specifications

• Cable type: flexible rubber-insulated lead (H05RRF / EPR)
• Conductor configuration: 3G (live, neutral, earth)
• Conductor cross-section: 2.5 mm²
• Length: 20 m
• Colour: black
• End fittings: fixed socket outlets
• Mechanical protection: robust rubber sheath resistant to abrasion and oils

How to use

Unwind the cable fully before applying mains voltage to avoid heat buildup and reduced performance. Connect the lead to a properly rated mains socket and plug the appliance or tool into the fixed socket outlets provided. Ensure that the total load connected does not exceed the safe current rating for 2.5 mm² conductors and that cables are routed to avoid sharp edges, moving parts and water ingress. For outdoor use, place connections above ground or within suitable weatherproof enclosures and inspect the sheath and plugs regularly for damage.

Usage recommendations

Use the cable for temporary and mobile power distribution where flexibility and mechanical resistance are required. Do not use the cable where permanent buried installation is needed or where the electrical rating of 2.5 mm² is insufficient for continuous heavy loads. Store the lead coiled in a dry place and inspect before each use to ensure safe operation.
