Yesterday, Nanjing Electric (Group) Co., Ltd. technical transformation project of UHV glass insulator glass furnace at the lighting ceremony.
Person in charge of the company, through this transformation, the new production line energy consumption per unit of production will drop 66%, glue stick with the production line baking furnace, hot commissioning is completed into production, Nanjing Electric EHV AC and DC will have a production capacity of full range of products, strength level of similar products in the world most of the 550 kN DC glass insulator will also benefit from off the assembly line.
UHV transmission with transmission capacity, transmission distance,glue gun the line loss is small and engineering investment and other advantages, is the development direction of long-distance transmission. UHP, ultra high voltage power transmission equipment is listed as the key to China's "Eleventh Five-Year" period focus on the development of one of the major technologies and equipment. The glass insulator especially UHV UHV DC glass insulator, it is one of the key pieces of insulation. The insulators used in high-voltage tower, which can withstand the pull of hundreds of tons. As for high technology products, manufacturing difficulties in the past, supporting the national grid needed for the building products has long depended on imports.
Shen Rong, general manager of the Nanjing Electric said that the Nanjing Electric is the first only the birthplace of glass insulators, in recent years, the company after several large-scale transformation to promote independent innovation, and now has a toughened glass insulator technology, all leading international intellectual property rights formation of a global (single) maximum glass insulator production base. Last year, the DC transmission line to meet the state building needs to fill the gaps, the company independently developed the 550 kN DC glass insulator, can be used to sign the world's highest voltage of 800 kV HVDC transmission project, the products of similar strength grade products for the world the most.
The total investment in technological transformation of the Nanjing Electric 120 million yuan of special high-voltage glass insulators Industrialization Project V Project. According to the industrialization of project implementation plan, 2011, the company formed an annual output of 1.4 million can be toughened glass insulator production scale, production and sales will grow from 3 million yuan to 6 billion yuan, becoming the world's leading manufacturer of glass insulators. The transformation also has a significant effect of energy saving, the new production line of fuel from the heavy oil to natural gas, energy consumption per unit of production fell 66%, the annual energy saving 11,000 tons of standard coal.
