Development of SD environmental protection type power cable plastic protection tube (bush)

With the incessant pushing ahead of the retrofit projects of moving the urban electric power cable into underground space,the prevention of the heavy metal pollution problem has gradually become the key point concerned about by the environmental departments. The research, manufacture and development of the power cable plastic protection tube that is endowed with environmental protection behaviours appear especially urgent. It is explained what should be done during the successive parts of the research work such as the definition of the environmental protection type power cable plastic protection tube and its technical requirements, the ingredients of the product, the production technology and forming machinery to meet the requirements of the environmental protection standards. The concerned examination items and behavior parameters are also illustrated. This product reaches the advanced level of the overseas similar products.
