Power cable requirements for turning radius
Number of page views:
The power cable has a larger outer diameter. In the transport, laying power cables more difficult.
Power cable on the turning radius of the requirements are more stringent. In the construction of the power cable, if the power cable turning angle is too large, it may damage the internal mechanical damage, and mechanical damage due to the power cable insulation cover and can not see, even if the measurement loop resistance, insulation and leakage test is also difficult to find Defects, overturning at the time of damage, the cable insulation strength is reduced until a fault occurs.
Most of the causes of power cable head failure are the length of the three cable heads when the cable head is made. When connected with the equipment, the cable head is long and the arch is damaged by the terrain. After taking measures, according to the connection of different equipment, the appropriate shortening of the length of the cable head connection, so that three-phase cable head are not external force, proved to run well. It can be seen, the power cable construction process, as far as possible to reduce the cable by the torque in the power cable turns and leave the cable, so that the cable in the natural bending, to prevent internal mechanical damage.
