Recently, two new "graphene composite high-semiconducting polyolefin shielding materials for cross-linked polyethylene insulated power cables rated at 35kV and below" and "35kV and below graphene composite high-semi conductive shielding crosslinked polyethylene insulated power cables" Product Technology Achievement Appraisal will be held in Yangxian Tea Culture and Ecology Park. Wu Shimin, Deputy Secretary General of Wire and Cable Branch of China Electrical Equipment Industry Association, Wu Changshun, director of State Quality Supervision and Testing Center for Wire & Cable, Suzhou Institute of Nanosciologists, Nanchang Institute of Graphene, Leaders attended the meeting.
The conference was organized and chaired by the wire and cable branch of China Electrical Equipment Industry Association. The conference was attended by the State Wire and Cable Testing Center, Research Institutes, Universities, Graphene R & D and Manufacturing Enterprises, Wire and Cable New Materials R & D Manufacturers, Wire and Cable Industry and Power Companies Eleven experts formed an appraisal committee. At the meeting, the experts conducted a careful review of the appraisal data, and examined the research and development conditions, production testing equipment and new product samples. The appraisal committee unanimously agreed that the formula, structure and process design of the new technology are reasonable and the addition of graphene is obvious Improve the conductivity and thermal stability of the semi-conductive shielding layer, and the relative technical indexes such as the volume resistivity of the semi-conductive shielding of the prototype are much better than that of the JB / T10738-2007 semi-conductive shielding material with the rated voltage of 35kV and below "And GB / T12706-2008" Rated voltage 1-35kV extruded insulated power cables and accessories "to fill the gaps in the country, the appraisal committee agreed that the two results through the technical appraisal, and hope that the early mass production and put on the market.
