CAN cable for commercial vehicles

The Lapp Group (Germany) will present in Hanover its CAN cable dedicated for commercial vehicles. It was designed to withstand heat and fire.

The Stuttgart-based Lapp Group will be showcasing a CAN cable for commercial vehicles such as fire engines at the Hannover Messe 2017. Lapp is thus expanding its range of Unitronic data cables. A durable spiral cable is another new addition.

The Unitronic Bus Heat 6722 is a data cable suitable for CAN networks. It is especially suitable for vehicle bodies. About 250 000 commercial vehicles are registered every year in Germany alone. They include fire engines, low loaders, or snow-clearing vehicles, for example. The launched cable withstands oil, petrol, diesel, lubricants, and UV light. It is also temperature-resistant between -40 °C and +105 °C in accordance with DIN/ISO 6722 Class B.

As this cable is also sometimes laid in passenger transport vehicles, certification under ECE R118 (Burning Behaviour of Materials Used in Interior Compartments) is mandatory. According to this regulation, the sheath material must be halogen-free so that, in the event of a fire, a person’s airways are not chemically burnt when the blazing plastic comes into contact with extinguishing water. As a result, only a sheath made of special polyurethane can be used here.

The cable also has a particularly small diameter. The provider’s engineers managed to achieve this by forming a star quad, also known as a twisted quad, with the cores in the cable. This saves space and weight and allows for narrow bending radii. The cable has a flexible sheath and fine-wired strands, so it is suitable for installation in moving applications such as an extendible fire ladder, for example. The product is available in four variants with core cross-sections of 0,25 mm2 to 0,75 mm2 to cover a variety of participant numbers and different cable lengths.

Spiral cable

The Unitronic Spiral is also intended for CAN networks. As its name suggests, the product is a spiral data transfer cable. This cable is particularly robust and designed for use in material handling or conveyor systems. The provider uses PUR sheaths for its spiral cables. Unlike PVC, PUR’s restoring force is retained for years – even when it is subjected to constant loading. This has been proven in tests performed in the supplier’s own test center, during which the cable was stretched and relaxed again 60 000 times. The spiral cable is available in two variants: shielded and unshielded. The core cross-section is 0,14 mm2 or 0,25 mm2.

Both cables will be on show at Lapp’s stand (C03) in hall 11 at Hannover Messe 2017.
