  • What materials are trailer cables made from?

    The cables are crafted from high-quality materials to ensure durability and safety:

     

    • Pure Copper and Oxygen-Free: These materials offer superior conductivity and prevent oxidation over time.

     

    • Bare Copper Conductors: Ensures better power transmission and reduces the risk of failure.

     

    • Reinforced PVC Jacket: Both the inner and outer layers of the cable are reinforced with PVC, providing enhanced durability and flexibility.
  • How durable are trailer cables?

    Trailer cables are designed for tough environments. Key features that enhance durability include:

     

    • Waterproof and Fire Retardant: Protects the wiring from exposure to moisture, reducing the risk of short circuits or damage.

     

    • Flexible and Durable: The cables remain pliable even in extreme temperatures, making them easier to install and less likely to crack or break.
  • How do I choose the right trailer cable for my needs?

    Consider the following factors to ensure you select the best cable for your trailer:

     

    • Number of Cores: Match the cable to the number of functions you need. If you’re only wiring lights, a 2-core cable may be enough. For more complex electrical systems, you might need a 5-core or 7-core cable.

     

    • Length: Make sure the cable is long enough to reach from the tow vehicle to the trailer, with some extra length to accommodate any bends or turns.

     

    • Environment: If your trailer will be exposed to harsh conditions, make sure the cable has waterproof and fire-retardant qualities for maximum protection.
  • Can I install the trailer cable myself?

    Yes, most trailer cables are easy to install with basic wiring skills. The flexible design and reinforced jackets make them easy to handle and connect. However, if you’re not experienced with electrical work, it’s always a good idea to consult a professional to ensure proper installation.
