Common protection of car wire harness
car wire harness protection generally use bellows, PVC pipe, PET winding tube, woven cloth, sponge, electrical tape to protect, and will use the cable ties, straps for fixed. Mainly on the car cable to play a fixed, wear-resistant, flame retardant, insulation, anti-corrosion, anti-interference, reduce noise and beautify the appearance of the role.
Protection mode one: bellows
Although the shape of the bellows are very similar appearance, but there are many kinds of material. Polypropylene (PP), nylon (PA), polypropylene modified (PPMOD), its main feature is good wear resistance, high temperature resistance, even the most common bellows high temperature can reach 100 ℃, and Flame resistance is better, the bellows itself has a good flexibility, good bending resistance. Bellows are the most common in cabin and front and rear protection structures.
Protection mode two: PVC pipe, heat shrink tube
PVC pipe for the soft PVC material, its function and similar to the bellows, the main features or soft, good anti-bending performance. But the wear resistance in general, temperature resistance can generally be 80 ℃ ~ 105 ℃. PVC pipe is mainly used for four doors and cab, and more for the beam points.
Protection of three: industrial plastic sheeting
Industrial plastic sheet material for the PVC, the appearance of a black mesh protection film, crimped after the dressing in the wiring harness, the main feature is good softness, easy to bend. Where the backbone harness needs to be bent, or where the thicker cable branches are visible, the wear resistance of the industrial plastic sheet is poor and is rarely seen.
