In the installation of high-temperature power cable when there are several things that must be noted, as follows:

1. The installation of the power cable shall be carried out by qualified professional units or professionals, and construction and installation that does not comply with the relevant requirements may result in the normal operation of the power cable system.

2. Manpower laying power cable, the command should be unified control rhythm, every 1.5 to 3 meters have a person carrying power cable, while pulling side, slowly cast.

3. Mechanical power cable, the general use of dedicated power cable laying machine and equipped with the necessary traction tools, traction size should be appropriate, the control should be uniform, so as not to damage the power cable.

4. cast power cable before, to check the appearance of the power cable and the head is intact, pay attention to the direction of the power cable tray rotation, do not crush or scratch the power cable outer jacket, in the winter when the low temperature should not beat To straighten the power cable, so as not to insulation, sheath cracking.

5. The bending radius of the power cable when laying is greater than the specified value. In the power cable laying before and after the installation of 1000V megger measurement power cable between the conductor insulation resistance is normal, and according to the silver tin high temperature line power cable model specifications, length and ambient temperature of the measurement results for appropriate correction, small size Power cable should also measure whether the conductor off.

6.power cable If buried directly, pay attention to soil conditions, the general building under the power cable buried depth of not less than 0.3 meters, while the soil is more soft or its surrounding environment is more complex, such as arable land, construction sites or roads , Laying the wire to have a certain depth of embedding (0.7 ~ 1 m), to prevent the buried power cable accidental damage, if necessary, should be erected obvious signs.

The above is a brief introduction to the caution of high-temperature power cable installation. To learn more about the power cable, please follow the kingsignal website.
