causing MC cable short circuit failure reasons and solutions
part-2 more information about Metal clad cable or armored cable.
According to customers' feedback, we found that in actual application Armored cable (MC CABLE)failure rate is higher than the failure rate of rubber cables, for armored cable, causing cable short circuit failure reasons normally as below:
(1) in the cable wiring, cable in the terminal wiring process does not meet the quality requirements.
Solution: we must comply with the cable wiring process requirements, in particular, pay attention to deal with the insulation of the middle end of the head, do not allow moisture to enter the key connection, to avoid affecting its insulation.
(2)Common problems: cable armor steel belt cracks, poor lap, cracks in the lead package into the moisture, especially in the cable in the end wiring weak links, so that the insulation is damaged and cause short circuit.
Suggestion: when installing on-site we should pay attention to the cable bending radius can not be too small, should not be less than 20 times the outer diameter of the cable.
