[0003]However, when the existing MPP power pipe is threaded, the power cable will directly contact with the pipe wall, which will increase the friction force, resulting in more laborious threading, and because the MPP The diameter of the power tube is large, and there are many cables passing through it. These cables are crossed and stacked together, which not only affects the later maintenance and replacement, but also generates a lot of heat when the cables are working. The heat dissipated is not good enough, there is a big safety hazard

Abstract
The invention relates to the technical field of electric power pipes, and discloses a heat-resistant and impact-resistant MPP electric power tube, which comprises a pipe tube, the tube body comprises an outer tube, an inner tube and a steel mesh layer, a filling cavity is arranged between the outer tube and the inner tube, the filling cavity is filled with a heat-conducting pressure-resistant material, and a plurality of pressure-resistant strips are distributed on the outer surface of the steel mesh layer at equal intervals. A center tube is arranged at the center of the inner side of the inner tube, a plurality of heat conduction plates are arranged on the outer side face of the center tube at equal intervals, a separation cavity is formed in the position, between every two heat conduction plates, of the inner side of the inner tube, and a plurality of sets of first balls are arranged on the position, in the separation cavities, of the inner side face of the inner tube at equal intervals. Multiple sets of second balls are annularly arranged on the surface of the center tube at equal intervals. The MPP electric power tube is high in heat conductivity and good in compression resistance, electric power cables can be separately placed, the problems that when a traditional MPP pipe is threaded, friction is caused between the electric power cables and the inner wall of the tube, and threading is strenuous and slow in speed are solved, and later cable replacement and maintenance are facilitated.
Description
technical field [0001] The invention relates to the technical field of power tubes, in particular to a heat-resistant and impact-resistant MPP power tube. Background technique [0002] MPP power pipe is also called MPP power cable protection pipe and MPP cable protection pipe. MPP power pipe adopts modified polypropylene as the main raw material. It does not need a lot of dredging, excavation and damage to the road surface. Construction projects such as laying pipelines and cables in special areas. [0003] However, when the existing MPP power pipe is threaded, the power cable will directly contact the pipe wall, thereby increasing the friction force, resulting in more laborious threading, and because the MPP power pipe has a larger diameter, more cables are threaded inside it , These cables are crossed and stacked together, which not only affects the later maintenance and replacement, but also generates a lot of heat when the cables are working. The traditional MPP pipe is...
