1 In the case of laying power cables along marshes or water, the whole power cable capable of withstanding tensile force should be selected.
When passing through a small stream, a power cable with armor (used outside the armor) should be used.
2 When the power cable is laid in different soils and different surrounding media, its model should be selected according to the most unfavorable conditions.
Otherwise, power cables with different structures should be used.
3 The use of copper core power cables for diesel engine rooms, air compressor rooms, forge rooms, and mobile machinery with severe vibrations, and the use of copper core power cables in other places should be strictly restricted.
4 Straight buried cables in the ground are generally made of bare plastic sheathed power cables.
When power cables are laid across railways, across tunnels, bridges, along the edges of roadbeds, and other places that may be mechanically damaged, armored power cables should be used.
There should be a protective layer outside the armor) or take protective measures (such as wearing a pipe)
