The RP Cable J1VV-U 3G2.5 (3×2.5 mm) is a single-strand three-conductor waterproof cable designed for outdoor electrical installations. Finished in black, its J1VV-U construction provides the weather resistance required for external wiring runs.

J1VV-U denotes a PVC-insulated and PVC-sheathed cable rated for outdoor use. The larger 2.5 mm² conductor cross-section compared to 1.5 mm² variants supports higher current-carrying capacity for more demanding outdoor circuits. Sold by the metre with a minimum purchase of 10 metres.

Key Features

• Three-conductor waterproof cable, J1VV-U type, 3G2.5 configuration (3×2.5 mm² cross-section)
• Designed for outdoor electrical installations
• Single-strand (solid) conductors
• Black outer sheath
• Sold by the metre; minimum purchase 10 metres

Product Benefits

• The 2.5 mm² cross-section provides higher current capacity than 1.5 mm² variants, supporting more demanding outdoor appliances and circuits
• J1VV-U rating provides weather resistance for outdoor installation without additional conduit in many applications
• Three conductors including protective earth allow wiring of earthed outdoor circuits in a single cable run
• Black sheath is less visible on dark external surfaces and resists UV degradation outdoors
