The Study On Crosslinkble Low Density Polyethylene Granules For Insulation Of High Voltage Power Cable

There are some disadvantages in the processing of the materials for the insulation of high voltage power cable in China such as the process equipments are complicate, which need more energy and the process flow is long and so on, we need to intake that vast scale from foreign enterprises yet. In order to change the present status, this paper has successfully developed the materials with new process equipments and new process flow, which are made with compounds containing universal resins of china and assistants such as peroxide, antioxidant and so on. The compounds are extruded through special equipments and process How at a temperature below the decomposition temperature of the peroxide after mixed in special equipments. The studied insulation materials have satisfied the national standards and have good process properties, which can replace the same level products of foreign and which can spare national foreign exchange and reduce cost for cable works.
