Electrical Cables

The electrical cables category (electrical wiring harnesses) is the nervous system of a bus. In a city or coach bus, the total cable length can range from several to a dozen kilometres. The quality, insulation and correct routing of the cables determine communication between control units as well as the trouble-free operation of the engine and safety systems.

Electrical Cables and Wiring Harnesses for Buses – Reliable Data and Power Transmission

In the 24V electrical system of a modern bus, electrical cables must withstand extreme conditions: constant vibration, contact with oils, fuel and road salt, as well as significant temperature fluctuations. Any abrasion of the insulation or breakage of a conductor inside the harness can immobilise the vehicle or cause faults in critical systems such as EBS or engine control (CAN bus). At Peterbus.pl, we offer complete wiring harnesses, ground cables and power cables for buses from Solaris, MAN, Mercedes-Benz, Volvo and Scania.

Types of cables and wiring harnesses in our range:

We supply ready-to-install solutions and components for repairing electrical systems:

• Engine and auxiliary equipment harnesses: Complete wiring connecting injectors and sensors (NOx, temperature and pressure) to the ECU.

• CAN bus cables: Specialist twisted-pair cables with high resistance to electromagnetic interference, essential for communication between on-board computers.

• Battery and starter cables: Large-cross-section cables (e.g. 50mm², 70mm², 95mm²) responsible for reliable engine starting and alternator charging.

• Door and lighting harnesses: Wiring supplying door opening mechanisms, interior LED lighting and exterior lamps.

• Ground cables (braided straps): Flexible connectors that compensate for potential differences between the frame and the engine or cab.

Why choose wiring harnesses and cables from Peterbus.pl?

A makeshift repair using standard domestic cables often ends in a fire or control unit failure. By choosing our products, you gain:

1. Resistance to aggressive media: We offer cables with fluoropolymer or reinforced PVC insulation, resistant to AdBlue, diesel fuel and greases.

2. Factory-fitted connectors (Plug & Play): Our harnesses are equipped with original connectors (e.g. Deutsch, Tyco, Bosch), ensuring sealed connections and fast installation without soldering.

3. Selection by VIN: The harness layout changes with every model update. Our experts will precisely select the right harness for your bus, eliminating the risk of incorrect connections.

4. New and used parts in excellent condition: We stock new service harnesses as well as fully operational, thoroughly tested used electrical harnesses removed from vehicles, allowing you to significantly reduce repair costs.

Keep the systems in your fleet communicating reliably. Explore the range of electrical harnesses and 24V cables at Peterbus.pl and choose professional wiring designed to withstand years of operation.
