Power cables have a small footprint; they are generally buried in the soil or laid indoors, in trenches, and tunnels. The insulation distance between lines is small, no poles or towers are required, and they occupy little space, basically no ground space; and power cables have high reliability, are less affected by climatic conditions and the surrounding environment, have stable transmission performance, and high reliability; but in the use of power cables, a protective mechanism is often required to protect the surface of the power cables, but the existing MPP power cable protection tubes have some shortcomings, such as:

[0003] Application number: CN202010661999.X is a MPP power cable protection tube with high strength and good pressure resistance. The device uses a clamping device to stably clamp both sides of the device with the tunnel to achieve stable placement, and then uses a conjoined column to connect with the connecting tube to achieve integrated fixation. The ground pressure is borne by the top plate, bottom plate and partition, which effectively avoids the damage of the tube body under pressure and improves the pressure resistance.
