According to the statistics, the national power grid corporation medium voltage cable rating since 2007 by more than 10% a year ratio increases year by year. Medium voltage cables also experienced from the paper insulation PVC cables, cable after XLPE ordinary cable to XLPE resists water tree cable development. And medium voltage accessories development also experienced around the bag accessories, heat shrinkable accessories, prefabricated type accessories, and cold attachment to swap type accessories development direction.fTQ【上海贝为电线电缆有限公司】

Statistics, the national power grid companies use high voltage cables in 2007 for 4610 km, 2008 a 20% increase over 2007 of 5540 kilometers, and in 2009 for 6610 km, 2010 for 7450 km. In domestic cable equipment manufacturing technology development and innovation, our country at present the high voltage cables and accessories has all realize localization.fTQ【上海贝为电线电缆有限公司】

In high pressure cables use, in 2008 and 2010 respectively achieved more than 20% of the increases in proportion. China now has high voltage cables all realization localization, but in annex products, the whole market products with existing domestic import coexist phenomenon.fTQ【上海贝为电线电缆有限公司】

In the future, high pressure extruded insulated cables and accessories in the grid is very important constituent, its long-term reliability is first of all to a very important problem. Current cable construction, we can see the cable insulation thickness of ultra high pressure due to the thick, heat mechanical effect is severe, with the higher the voltage, the body and the cable accessories designed and installed to cooperate becomes more difficult.fTQ【上海贝为电线电缆有限公司】
