环保型电力电缆塑料保护管的研制

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

随着城市电力电缆入地改造工程的不断推进,防止地下水重金属污染问题已成为环境关注重点,具有环保性能的电力电缆塑料保护管的研制开发尤显迫切。文章就环保型电力电缆塑料保护管的定义与技术要求;产品配方、生产工艺、成型设备等诸环节如何确保环保标准要求以及相关检验项目、性能参数作了说明。该产品已达到国际同类产品先进水平。

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 thee environmental protection standards. The concerned examination items and behavior parameters are also illustrated. This product reaches the advanced level of the overseas similar products.
