The important purpose of wiring harness is to wear resistance, high temperature resistance, flame retardant, corrosion prevention, interference prevention, noise reduction, beautify the appearance of the role. It is not only the medical wiring harness that needs to be bandaged and protected, but other wiring harnesses as well.

1: bellows: the main characteristic is good wear resistance, high temperature resistance, flame retardancy, heat resistance in high temperature area are very good. Usually, the temperature resistance of bellows is between -40 and 150℃. Its material has PP and PA two kinds. PA material is better than PP material in flame retardant and wear resistance. But PP material is stronger than PA material in bending fatigue resistance. Usually the opening can be plugged directly into the wire harness.

2: PVC pipe: its function and bellows, mainly used for wiring harness turning branch, in order to make the wire smooth transition, that is due to the PVC pipe softness and resistance to bending deformation is better, and PVC pipe is generally closed. The heat resistance temperature of PVC pipe is not high, generally below 80℃.

3: adhesive tape: its role is in the wiring harness to bundle, wear resistance, insulation, flame retardant, noise reduction, for identification, etc. Thread tape is generally divided into three kinds: PVC tape, air flannelette tape and duct tape. PVC tape has good wear resistance and flame retardancy; The temperature resistance is about 80℃, the noise reduction is not good, and the price is cheaper. The material of flannelette tape and duct tape is PET. Flannelette tape has the best binding and noise reduction, and the temperature resistance is about 105℃. Bucky tape has the best wear resistance and the highest temperature resistance is about 150℃. The common disadvantage of flannelette tape and duct tape is poor flame retardancy and high price.

As an important link connecting the components of the medical equipment, the medical wiring harness should be protected by the pericardial bandage to prolong the service life of the medical wiring harness.
