Abstract

The invention discloses an MPP power cable protection pipe, and a connection assembly of the protection pipe. The MPP power cable protection pipe comprises the following raw materials in parts by weight: 70-80 parts of polypropylene, 15-20 parts of ultra-high molecular weight polyethylene, 6-8 parts of nano calcium carbonate, 3-5 parts of modified talc powder, 3-5 parts of glass fiber, 1-2 parts of a coupling agent, 2-3 parts of an antibacterial agent, 3-5 parts of a plasticizer, 1-3 parts of an antioxidant, and 1-2 parts of a compatibilizer. Polypropylene as a matrix, and the added ultra-highmolecular weight polyethylene and modified talc powder are used as a preparation base material of the MPP power cable protection pipe, and the rose crystalline nanometer calcium carbonate and other processing aids are matched to form a multi-dimensional MPP power cable protection pipe material. The connection assembly of the MPP power cable protection pipe comprises a connection sleeve body and fixing sleeves, and the connection operation of the MPP power cable protection pipe is simple and fast through the connection assembly, so that the fast construction of a power cable in the power engineering is facilitated.

Description

technical field

[0001] The invention belongs to the technical field of power cables, in particular to an MPP power cable protection tube and a connection assembly thereof. Background technique

[0002] With the development of urban construction in our country, the construction of underground pipelines, especially the laying of power sheathed pipes, has become an indispensable part of urban construction.

[0003] MPP power cable protection pipe adopts modified polypropylene as the main raw material. It does not need a lot of dredging, excavation and damage to the road surface, and it is not necessary to lay pipes, cables and other construction projects in special areas such as roads, railways, buildings, and river beds. Compared with the traditional "grooving and buried pipe method", the non-excavation power pipe project is more suitable for the current environmental protection requirements, and removes the dust, traffic congestion and other disturbing factors caused by tradi...
