The Surface Temperature of Enameled Copper Clad Aluminum Wire

  •  


    When the Enameled Copper Clad Aluminum Wire(XINYU-ENAMELEDLIGHT) passes through a certain load current, it will be heated. With the increase of the load current, the higher the surface temperature of the enameled copper clad aluminum wire, if it is not handled in time, the consequences can be imagined. If the enameled copper clad aluminum wire is taken as the upper limit of the core temperature of 70 degrees, the surface temperature is 5-10 degrees. Therefore, the surface temperature of the enameled copper clad aluminum wire is basically safe below 60 degrees. Considering the maintenance of the power supply, the lower the better of course.


    The reasons for the heating of enameled copper clad aluminum wire during operation are as follows: the conductor resistance of enameled copper clad aluminum wire does not meet the requirements, resulting in heat generation during operation. improper selection of enameled copper clad aluminum wire leads to too small conductor cross-section and overload during operation. after a long period of time, the heating and heat dissipation of enameled copper clad aluminum wire is caused by an imbalance of heat.


    When installing enameled copper clad aluminum wires, the arrangement is too dense, the ventilation and heat dissipation effects are not good, or other wires are close to the heat source, affecting the normal heat dissipation. If the joint manufacturing process is not good, the pressure is not tight enough, and the contact resistance of the joint is too high, heat will also be generated from the enameled copper clad aluminum wire.


    Due to poor insulation performance and small insulation resistance, heating will also occur. When the local sheath is damaged, water will slowly damage the insulation performance and the insulation resistance will gradually decrease. The heating phenomenon will lead to the operation of the enameled copper clad aluminum wire. If the enameled copper clad aluminum wire is heated, if the cause is not found in time, the fault will be eliminated in time. The insulation fault will occur after the enameled copper clad aluminum wire is continuously energized. The interphase short circuit tripping phenomenon is serious and may cause a fire.
