" High voltage cable insulation material made breakthrough of domestic high voltage cable production of raw materials bottlenecks, the production cost is greatly reduced, which is beneficial to not only the domestic cable industry's healthy development, but also conducive to domestic cable enterprises into the international, digestion domestic high voltage cable production line and rich production capacity. " Wu Changshun accepted the " China Electric Power News " interview that, at present domestic high voltage tower production line has been severely pile up in excess of requirement, in full production status, domestic high voltage cable capacity can meet the demand of the world.

In addition to technical backwardness advantage outside, domestic high voltage cable insulation material in production cost, transportation cost and delivery cycle, with imported products have obvious advantages, it has become the domestic high voltage cable market promotion, eventually achieve import substitution is strong assure.

In addition polymer from foreign custom set of high voltage insulation material after sucking method production equipment, also set up a vertical tower type full closed purification workshop, equipped with high-precision testing equipment, fully meet the production requirements of high voltage cable.

In fact, the cyclones polymer and foreign chemical giants in the high voltage insulation material field competition, is the middle of 90's last century in medium voltage insulation material field competition continues. Prior to this, the domestic medium voltage
