15-core kabel
In the construction and maintenance of trailers and semi-trailers, electrical wiring plays a fundamental role in the reliability and safety of the entire vehicle. The 15-core cable has become a well-established solution in the truck workshop precisely because it consolidates multiple electrical functions into a single cable assembly, reducing installation complexity and improving long-term serviceability.
The cable is built around a conductor configuration that reflects the practical demands of trailer and HGV electrical systems. Three conductors of 2.5 mm² handle connections with higher current requirements, while twelve conductors of 1.5 mm² serve the signal and control circuits. This arrangement allows a single cable run to cover both the main power connections and the full range of signalling and switching functions found in modern trailer installations. For trailer builders and bodywork specialists, this translates directly into fewer cable ducts, fewer connectors, and a cleaner, more maintainable installation.
One of the most significant use cases for the 15-core cable is the electrical wiring of vehicles subject to ADR/GGVS regulations, covering vehicles used for the transport of dangerous goods. The conductor layout, with heavier cores for primary connections and lighter cores for control circuits, is well suited to the specific electrical requirements that apply to these vehicles. In the truck workshop, this cable is regularly specified for the construction or conversion of tankers, chemical transport vehicles, and other HGV types where ADR/GGVS compliance is mandatory.
For standard trailers and semi-trailers, the internal wiring beyond the standardised coupling is always custom-built to the specific vehicle layout. The 15-core cable addresses this need effectively. The twelve 1.5 mm² conductors are suitable for lighting circuits including indicators, brake lights, side markers and number plate illumination, as well as sensor and control signals. The three 2.5 mm² conductors provide capacity for heavier loads such as electropneumatic valves, refrigeration units or electrically controlled hydraulic systems.
In the day-to-day environment of a truck workshop, the 15-core cable is typically purchased in longer runs and cut to the required length based on the specific trailer design. It is routed along the chassis or bodywork structure, secured in cable ducts or with cable clamps, and connected to junction boxes or distribution modules. The integrated multi-core construction means fewer individual cables need to be routed, which shortens installation time and reduces the risk of wiring errors during assembly.
Whether the application involves building a new semi-trailer from scratch, converting an existing vehicle to meet updated transport regulations, or carrying out scheduled maintenance on a fleet of HGVs, the 15-core cable provides the conductor configuration and practical characteristics needed to complete the electrical installation to a professional standard. It is a reliable and technically sound choice for trailer builders, bodywork specialists, and operators with in-house workshop facilities working across the full range of trailer and HGV applications.
