The reasons for cable failure can be divided into two categories, one is the failure of the cable insulation layer, including the aging and corrosion of the cable insulation layer. This kind of fault usually causes a circuit short circuit, burn, and so on. The other is cable breakage, generally caused by external mechanical forces, such as construction errors, extreme weather, and so on.
Generally speaking, the cable insulation layer failure is unably repaired, restoring the circuit is to replace the cable. However, the cost of replacing the circuit cable is relatively high, so it is very important to choose the high-quality cable suitable for the circuit and the routine maintenance of the circuit.
For the fault of cable breaking, two wires can be connected to repair the fault on the premise that the circuit stability is not affected.
