Technical Field
The invention relates to the technical field of power pipeline processing, in particular to a MPP power cable protection pipe processing device.
Background
The MPP pipe is also called MPP power cable protection pipe and is divided into excavation type and non-excavation type, and the MPP non-excavation pipe is also called MPP pipe or dragging pipe. The MPP pipe adopts modified polypropylene as a main raw material. The cable duct has the characteristics of high temperature resistance and external pressure resistance, and is suitable for medium and low voltage transmission lines and cables arranged in a duct body below 10 KV; the MPP adopts modified polypropylene as a main raw material, and is a construction project for laying pipelines, cables and the like in special sections such as roads, railways, buildings, riverbeds and the like without digging a large amount of mud, digging soil and damaging road surfaces. Compared with the traditional 'trenching and pipe burying method', the trenchless power pipe engineering is more suitable for the current environmental protection requirement, and the disturbing factors such as dust flying, traffic jam and the like caused by the traditional construction are eliminated, so that the technology can also lay pipelines in some areas which can not implement the trenching operation, such as historic site protection areas, downtown areas, crop and farmland protection areas, expressways, rivers and the like.
