1, we do the experiment with the test wire and the cable should not be attached to the semi-conductive layer too close, so easily lead to breakdown occurred.

2, the elbow-type head should be installed in the yellow mark line cover, in the installation process can hear the "bass" is heard, according to this feature can explain the installation of heat shrinkable cable accessories in place in place.

3, due to special circumstances, the staff did not connect the ground wire firmly, heat shrink cable accessories will be connected with the ground line discharge. At this time, usually with high-voltage electroscope inspection will show a power.

4, sometimes in the absence of cable in the case of semi-conductive layer stripped too much, we can take the following measures: the use of semi-conductive layer of layers of recovery, to achieve the same as possible with the original to ensure that and cable accessories Of the semi-conductive layer of reliable contact. Remember not to do anything, the term is natural.

5, we are doing the test should be in accordance with the provisions of the rules, in the humidity, the temperature is low, the strict is not allowed to work. But the vast majority of the site do not comply with this provision, in order to ensure the safe operation of equipment to take appropriate measures. Rain construction must do a good job protection work, to avoid the cable accessories on the water, damp. In the low temperature construction, but also pay attention to the cable preheat.
