Description

MPP power tube connecting piece Technical Field The utility model relates to the technical field of pipeline connection, in particular to an MPP power pipe connector. Background The MPP power tube, which is totally called a modified polypropylene power tube, is a tube special for power engineering, has higher compressive strength, can bear the loads such as soil and ground pressure and vehicles, is not easy to deform, and ensures the safe operation of a power cable. For example, in road construction, even if a large construction machine is operated on top of it, an MPP power pipe buried underground can be kept intact. In connecting an MPP power tube to a connection, a more complex manner of operation, such as a conventional hot melt connection or threaded connection, may be required. The hot melting connection needs professional hot melting equipment, the hot melting part is required to be cooled and solidified, the process is time-consuming, the screw thread connection needs manual screw thread tightening, the operation difficulty is high for a large-caliber power tube, the screw thread tightening process is slow, the installation efficiency is low, the connecting piece or the power tube is required to be damaged to separate the connecting piece or the power tube, the waste of materials is caused, and the installation time and the installation cost are increased. When receiving external slight pulling force, thrust or vibrations after connecting two MPP electric power pipes well, produce relative displacement easily between connecting piece and the pipeline, lead to connecting looseness, even make two pipeline separation, influence the normal operating of electric power pipe system, along with the lapse of time, probably unable dead weight and the pressure of long-term bearing pipeline, lead to connecting portion to warp gradually, loosen to lead to influencing the insulating properties of pipeline inner cable, increase the risk of power transmission trouble, destroy the stability and the integrality of entire system. Disclosure of utility model The utility model mainly aims to provide an MPP power pipe connecting piece, which can effectively solve the problems that the installation efficiency is low, the connecting piece or the power pipe is required to be damaged to separate, the material waste is caused, the installation time and cost are increased, the insulation performance of a cable in a pipeline is affected, the risk of power transmission failure is increased, and the stability and the integrity of the whole system are damaged.
