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

The Heavy-Duty 5-Core Automotive Trailer Electrical Cable is an industrial-grade multi-conductor wiring harness engineered to deliver dependable low-voltage power distribution and road-signaling connectivity for commercial trailers, utility haulers, touring caravans, horseboxes, and agricultural equipment. Specifically manufactured for multi-function trailer light setups, this cable provides dedicated circuits for earth (ground), left-hand indicator, right-hand indicator, rear position/tail lights, and stop (brake) lights without requiring multiple loose wire runs.

Constructed with five color-coded, high-conductivity 0.75 mm² stranded copper conductors, the harness ensures minimal voltage drop and long-term signal integrity across extended trailer lengths. The internal conductors are encased in a flexible, heavy-duty automotive PVC outer sheath that offers exceptional resistance against oil, fuel splash, road grit, abrasion, moisture, and prolonged UV exposure. Available in practical continuous lengths ranging from 5 meters up to 50 meters (in 5-meter increments), it accommodates everything from compact utility trailer rewires to complete multi-axle fleet harness fabrications.

Key Features & Benefits:

• 5-Core Multi-Function Layout: Consolidates all core trailer lighting circuits—left turn, right turn, brake, tail/running, and earth ground—into a single, organized, easy-to-pull cable loom.

• High-Conductivity 0.75 mm² Copper Conductors: Fine-stranded, pure copper cores ensure maximum conductivity, low electrical resistance, and flexible routing through tight chassis channels and drawbars.

• Standard Automotive Color Coding: Individually color-insulated internal cores simplify identification, termination, and circuit tracing into standard 7-pin plugs, sockets, and rear junction boxes.

• Heavy-Duty Protective PVC Sheathing: Tough outer insulation resists road salt, diesel, grease, continuous chassis vibration, and abrasive rub points along trailer frames.

• UV & Weather Resistant: Engineered to withstand harsh outdoor weathering, direct sunlight, rain, and wide temperature swings without cracking, hardening, or peeling.

• Versatile Length Selections: Available in continuous lengths from 5 m up to 50 m (sold in 5 m increments) to reduce wire wastage and eliminate unnecessary intermediate splices.

Ideal Applications:

• Utility & Cargo Trailers: Main chassis wiring looms for single- and tandem-axle box trailers, flatbeds, and plant carriers.

• Caravans & Camper Trailers: Complete internal and underbody electrical harness routing for road travel lights on campers and touring caravans.

• Horseboxes & Livestock Transporters: Durable wiring harness capable of withstanding rough rural roads and routine undercarriage washdowns.

• Boat & Marine Trailers: Water-resistant chassis wiring runs for boat trailers, jet ski haulers, and slipway launch boards.

• Agricultural Implements: Electrical signaling leads for tractor-towed wagons, fertilizer spreaders, and water bowsers.
