Extension cable Bachmann 343.177 25 m H05RR-F 3G1 — heavy-duty flexible power lead

Extension cable Bachmann 343.177 25 m H05RR-F 3G1 — heavy-duty flexible power lead is a 25-metre rubber-insulated mains lead designed for temporary power distribution. The cable uses H05RR-F construction with three conductors of 1.0 mm² cross-section (3G1), providing a flexible connection for portable appliances, power tools and outdoor equipment. Its rubber outer sheath offers mechanical resistance and suitability for applications where bending and movement occur frequently.

Advantages

The rubber-insulated H05RR-F design delivers increased flexibility compared with PVC-only cables, improving handling and reducing stiffness in lower temperatures. A 25 m length extends reach without additional joints, while the 3G1 conductor configuration provides a standard mains connection with protective earth. The cable construction emphasises abrasion resistance and mechanical durability for temporary installation and mobile use.

Suitable for

• Temporary power supply for portable power tools on construction or renovation sites
• Connecting household appliances at greater distance from fixed sockets
• Outdoor equipment and garden machinery where flexible mains leads are required
• Events and temporary installations requiring robust, movable power distribution

Key specifications

• Length: 25 m
• Cable type: H05RR-F
• Conductors: 3 cores
• Conductor cross-section: 1.0 mm² (per core)
• Conductor arrangement: 3G1 (live, neutral, earth)
• Insulation and sheath material: rubber-based compound (flexible)
• Application: temporary flexible mains connections

How to use

Unroll the extension cable fully before use to avoid heat buildup. Connect the plug to a compatible mains socket and ensure the protective earth is present and functional. Route the cable to avoid sharp edges, tension, or crush points and keep the lead clear of pedestrian pathways where possible. For outdoor use, confirm that connected equipment and any in-line connections have appropriate ingress protection; avoid prolonged exposure to direct sunlight and chemicals that can degrade rubber sheaths.

Recommendations

Inspect the cable visually for cuts, nicks or exposed conductors before each use. Do not use the cable if the sheath or conductors are damaged. Avoid permanent installation; use the lead for temporary or mobile applications only. Store the cable dry and coiled without tight bends to preserve flexibility.
