Zhejiang Photovoltaic Cable

Parallel failure is the guidance of the insulation between the outer skin or the conductor, and can not withstand the normal operating voltage. The actual combination of faults is many. Several types of faults are more likely to be: one opposite, two opposite and one phase broken and grounded. Power cable failure causes and detection technology Cable failures are defined as: no damage failure.

Open circuit fault, short circuit fault. Cable faults are classified into three types: open circuit fault, low impedance fault and high impedance fault. (1) Open circuit failure, if the cable phase or relative insulation resistance reaches the required specification value, but the working voltage cannot be transmitted to the terminal; or although the terminal has voltage, the load capacity is poor. When the insulation resistance = ∞, it is the disconnection fault (2) low resistance fault, cable phase or relative insulation damage.
