  The cause of the heating of the booster cable during operation

  Boost cable through a certain load current, it will heat, with the load current increases, the cable surface temperature is higher, if not timely treatment, the consequences can be imagined. Such as: PVC (PVC) cable, is the core temperature of 70 degrees for the upper limit to consider, the surface temperature will be 5 to 10 degrees lower. So the cable surface temperature below 60 degrees is basically safe, from the power maintenance considerations, of course, the lower the temperature the better.

  The cause of the booster cable during operation is as follows:

  1, the cable conductor resistance does not meet the requirements, resulting in the cable in the operation of the heat generated.

  2, the cable selection type improper, resulting in the use of cable conductor cross-section is too small, the operation of the overload phenomenon, prolonged use, the cable heat and cooling imbalance caused by fever.

  3, the cable is arranged too tightly arranged, poor ventilation and cooling effect, or cable close to other heat sources too close to the normal cooling of the cable, may also cause the cable in the operation of the heat generated.

  4, joint manufacturing technology is not good, crimping is not close, resulting in connector contact resistance is too large, will cause the cable to produce heat phenomenon.

  5, the cable insulation performance is not good, resulting in smaller insulation resistance, the operation will also produce heat phenomenon.

  6, armored cable local sheath damage, after the water on the insulation performance caused by slow damage, resulting in a gradual reduction in insulation resistance, will also cause the cable to produce heat in the phenomenon.

  Booster cable generated after the phenomenon of heat, if not find the reasons for troubleshooting in a timely manner, the cable will continue to run after the continuous operation of the thermal breakdown of the phenomenon. Causing the cable to occur in a short circuit trip phenomenon, serious may cause a fire.
