Temperature resistance of Yongle Automotive Wire Harness Tape

Temperature resistance of Yongle Automotive Wire Harness Tape

The low temperature resistance requirement of the whole vehicle harness is - 40 ℃. The main difference is that the high temperature resistance requirements are different. The ambient temperature at different positions on a vehicle body is different. The harness tape leads to different high temperature resistance requirements for the tape for wire harness at different positions. The high temperature resistance of the tape is required to be 105 ~ 150 ℃ in the engine room and 85 ~ 105 ℃ in the cab. The following is the specific analysis.

For the harness in the engine compartment, the ambient temperature in the engine compartment is the highest. In some specific locations, such as above the engine block, the maximum storage temperature can reach 135 ℃, and the maximum storage temperature under the engine hood can also reach 95 ℃. Therefore, the place closest to the engine requires high temperature resistance of the tape.

The tape used on the engine harness generally has two functions: the wire harness does not have a protective sleeve, and the tape plays a main protective role. At this time, the high temperature resistance of the tape must reach 130 ℃, the wire harness has a protective sleeve, and the tape mainly plays the role of fixing the protective sleeve. At this time, the high temperature resistance of the tape must be above 105 ℃.

Indoor harnesses, such as instrument panel harness, indoor floor harness, ceiling harness and four door harness, are located inside the machine room. The high temperature resistance of the Yongle Automotive Wire Harness Tape used in the harness can meet the requirements when it reaches 85 ℃.
