Common construction failure causes and preventive measures of Heat Shrinkable Joint Kit

2023-04-03
With the increasing popularity of the application of cable Heat Shrinkable Straight Through Joint Kit, cable fire accidents caused by short circuit of cable Heat Shrinkable Straight Through Joint Kit often occur in many large and medium-sized enterprises. The fault of Heat Shrinkable Straight Through Joint Kit is mostly construction fault, and the most common reason is short circuit fault caused by process error.

Some of the Heat Shrinkable Straight Through Joint Kit defects caused by process errors can be found in time through handover experiment, while others can only be exposed after a long time of operation. According to the analysis of the operation situation, there are two main cases of short-circuit fault formation in the short term:

1. Blindly lengthening the sliding distance of the joint, wrongly changing the internal and external insulation pipes from overlapping to lapping, resulting in insufficient insulation strength at the nozzle to form a short distance.

2. The cable is damp due to the poor sealing of the joint jacket tube, which forms sliding and flashing, leading to the failure.

For the improper use of Heat Shrinkable Straight Through Joint Kit insulation, as long as the construction is strictly in accordance with the process specifications, the problem is not difficult to solve. In the case of poor sealing, in addition to paying attention to the polishing, cleaning and adhesive heating of the cable sheath, attention should also be paid to the wrapping and filling of both ends of the internal and external insulation pipe should be dense to form a backup seal. In this way, when the cable is accidentally damp (such as water when the sheath is damaged), it can prevent water intrusion along the core insulation surface, avoid slipping and blitzing through, and extend the service life of the joint.
