The Causes of Heating During Cable Operation

The cross-section of the cable conductor is too small. And overload occurs during operation for a long time resulting in unbalanced heating and heat dissipation.

The cable is too densely arranged during installation in that the performance of ventilation and heat dissipation is not good. Or the cable is too close to other heat sources, which affects the normal heat dissipation of the cable.

 The crimp at the cable joint is not tight, resulting in excessive contact resistance at the joint.

Cable phase insulation performance is not good, resulting in low insulation resistance.

The partial sheath of armored cable is damaged.

If the heating failure cannot be eliminated in time insulation thermal breakdown will occur after the cable continues to run continuously, resulting in inter-phase short-circuit tripping of the cable, which may cause a fire in serious cases.
