MPP改性聚丙烯电力管简介

Brief introduction of MPP modified polypropylene power pipe

MPP管又称MPP电力电缆保护管，分为开挖型和非开挖型，MPP非开挖管又称作MPP顶管或拖拉管。MPP管采用改性聚丙烯为主要原材料。具有抗高温、耐外压的特点，适用于10KV以下中低压输电线电缆排管管材。

MPP pipe, also known as MPP power cable protection pipe, is divided into excavation type and trenchless type. MPP trenchless pipe is also known as MPP jacking pipe or drag pipe. MPP pipe adopts modified polypropylene as the main raw material. With the characteristics of high temperature resistance and external pressure resistance, it is suitable for the pipe material of medium and low voltage transmission lines and cables below 10kV.

中文名:  MPP管            别    名:    MPP电力电缆保护管

Chinese Name: MPP pipe alias: MPP power cable protection pipe

Classification: excavation type and non excavation type features: high temperature resistance and external pressure resistance

MPP采用改性聚丙烯为主要原材料，是无须大量挖泥、挖土及破坏路面，在道路、铁路、建筑物、河床下等特殊地段敷设管道、电缆等施工工程。与传统的“挖槽埋管法”相比，非开挖电力管工程更适应当前的环保要求，去除因传统施工所造成的尘土飞扬、交通阻塞等扰民因素，这一技术还可以在一些无法实施开挖作业的地区铺设管线，如古迹保护区、闹市区、农作物及农田保护区、高速公路、河流等。本产品通过化学建材测试中心的检测，取得了较好的社会效益和经济效益。

MPP uses modified polypropylene as the main raw material, which is a construction project for laying pipelines and cables in special sections such as roads, railways, buildings and under the riverbed without massive dredging, soil excavation and pavement damage. Compared with the traditional "trenching and burying pipe method", the trenchless power pipe project is more suitable for the current environmental protection requirements and removes the disturbing factors such as dust and traffic congestion caused by the traditional construction. This technology can also lay pipelines in some areas where the excavation operation cannot be carried out, such as historic sites protection areas, downtown areas, crop and farmland protection areas, highways, rivers, etc. This product has passed the test of chemical building materials test center and achieved good social and economic benefits.

MPP电力管施工须知
