MPP power cable protection pipe joint is a common cable protection device, and its bending use method is very important. Correct bending operations ensure that the cable is not damaged in the curve and guarantees the stability of power transmission. The following will introduce the method of correct bending of MPP power cable protection pipe joints.

First of all, the turning margin should be kept within a safe range. If the bending amplitude is too large, the cable will generate too much pressure, causing the cable to break or deform, which in turn will affect the power transmission effect. Therefore, the operator should pay attention to the maximum allowable bending radius of the cable when carrying out the bending operation, and try to control the bending amplitude within a safe range.
Second, avoid over-bending when cornering. Excessive bending can cause excessive stress to be created inside the cable, which can damage the cable's insulation and conductors. To avoid excessive bending, appropriate bends or elbows can be used to relieve the bending pressure of the cable and protect the integrity of the cable.
In addition, the operator should avoid being too fast or too slow when cornering. Excessive bending speed will cause the cable to withstand large impact forces, which can easily cause breakage or loosening. Slow bending speeds, on the other hand, can put constant stress on the cable, which can also cause damage to the cable. Therefore, the operator should pay attention to controlling the speed and maintaining stability when performing the turning operation.
In addition, it is important to choose the right turning radius. A suitable bending radius can reduce the stress concentration inside the cable and reduce the risk of damage. The specific bending radius selection should be determined according to the type and specification of the cable, and it is generally recommended to refer to the relevant standards or consult the advice of professional engineers when using.
Finally, regular inspection and maintenance are also important to ensure that cable protection joints are bent correctly. The operator should regularly inspect the cables and joints, and deal with the problems in time. At the same time, a flexible joint device can be used at the bend to reduce the stress and pressure of the cable.
To sum up, the correct bending operation is the key to ensure the normal operation of the MPP power cable protection pipe joint. The operator needs to pay attention to factors such as bending amplitude, excessive bending, bending speed, and bending radius to ensure the safety and stability of the cable. Regular inspection and maintenance is also very important to ensure the integrity and longevity of the joints. Only reasonable use and maintenance can ensure the stability and safety of power transmission.
