Cable to power, machinery, aerospace The development of has played an important role, and has become the industry with the highest output in China. Therefore, cable quality, service life, safety and performance have become issues of concern. However, in practice, cable quality is not the main method to ensure safety, and cable installation and maintenance also play a major decisive factor. The following are the common precautions for the use of cables:
1. The connecting bolts at the cable connection shall be tightly linked
