Heavy-Duty 7-Core Automotive Trailer Electrical Cable (5m to 50m Length Options)

The Heavy-Duty 7-Core Automotive Trailer Electrical Cable is an industrial-grade multi-conductor wiring harness engineered to deliver dependable low-voltage power distribution and comprehensive signaling connectivity for commercial trailers, heavy transport rigs, touring caravans, horseboxes, and agricultural equipment. Manufactured specifically for complete 7-pin road-lighting configurations, this cable provides all necessary dedicated circuits—including ground (earth), left-hand indicator, right-hand indicator, stop (brake), tail/running lights, reverse, and auxiliary power—within a single, unified harness.

Constructed with seven color-coded, high-conductivity 0.75 mm² stranded copper conductors, this wiring harness ensures minimal electrical resistance, reduced voltage drop, and consistent signal transfer across extended trailer spans. The internal cores are bundled inside a flexible, heavy-duty automotive PVC outer sheath designed to withstand continuous chassis vibration, abrasive contact along frame channels, road grime, fuel splashes, and severe weather exposure. Available in continuous lengths ranging from 5 meters up to 50 meters (in practical 5-meter increments), it provides an efficient solution for minor repairs, complete re-wires, or custom commercial harness builds.

Key Features & Benefits:

• Complete 7-Core Functionality: Consolidates all standard 7-pin electrical circuits into a single protective jacket, eliminating loose, tangled wiring along the drawbar and chassis.

• High-Conductivity 0.75 mm² Copper Conductors: Multi-stranded copper cores provide flexible routing through tight drawbar channels while maintaining high electrical conductivity and minimal voltage drop.

• Standard Automotive Color Coding: Individually colored internal conductor jackets allow fast, intuitive circuit identification and error-free wiring into standard 7-pin plugs, sockets, and junction boxes.

• Heavy-Duty Protective PVC Sheathing: Durable automotive-grade outer jacket protects against stone strikes, chassis rub points, oil, grease, road salts, and continuous vibration.

• Weather & UV Resistant: Engineered for outdoor commercial service, resisting cracking, hardening, and degradation caused by extreme sunlight, rain, and temperature fluctuations.

• Flexible Length Selection: Offered in continuous lengths from 5 m to 50 m (sold in 5 m increments) to match specific trailer dimensions and eliminate unnecessary intermediate joins.

Ideal Applications:

• Commercial & Utility Trailers: Full chassis wiring runs for tandem-axle trailers, flatbeds, box trailers, and plant equipment transporters.

• Touring Caravans & Campers: Complete electrical supply lines linking the vehicle hitch connection to rear combination lamps, side markers, and internal auxiliary circuits.

• Horseboxes & Livestock Transporters: Resilient electrical harnessing capable of withstanding rough rural roads and routine high-pressure chassis washing.

• Boat & Marine Trailers: Durable main chassis wiring runs for boat trailers and marine transport carriages.

• Agricultural & Heavy Machinery: Wiring harnesses for tractor-towed implements, mobile power generators, and towed bowsers.
