Recently, entrusted by the Jiangxi provincial science and Technology Department, the Pingxiang Municipal Science and Technology Bureau organized some experts in Nanchang to hold the 2011 key new product plan project of Jiangxi Province, which was undertaken by three Switzerland Technology (Jiangxi) company, "the UDG550B240/710H32R glass insulator for the ultra high voltage transmission line of the DC system", the provincial new product and the municipal achievement appraisal Meeting。
It was identified by the expert group that the UDG550B240/710H32R glass insulator of the ultra UHV transmission line of three Rui science and Technology Co., Ltd. was optimized by formula. The mixture base effect and the repression effect were fully utilized to prevent or slow the migration of Na+. The low melting temperature, easy forming and tempering were developed. The glass formula with high resistivity is designed with the combination of long short staggered edge and bell shaped edge, which has the function of effective anti fog erosion and hindering the development of local arc. The structure is reasonable and the anti pollution performance is good.
The company adopts the new technology and equipment such as high efficiency, energy-saving and environmental protection all electric furnace, five stage warm furnace, telescopic downwind grid steel technology, step type automatic transmission technology and nickel sulfide homogenizing furnace. The product has excellent performance and can meet the requirements of ultra high voltage direct current transmission line. The experts listened to the report of the group, examined the production site and examined the related materials. After inquiry and discussion, the committee considered the two products to reach the advanced international level.
