Power cable insulation material divided by 1, oil impregnated paper insulated power cable with oil paper for insulation of power cables. Its application longest history. It is safe, reliable, long life, low prices. The main disadvantage is subject to drop restrictions on the laying. Since the development of not trickle impregnated paper insulation, to solve the problem of drop restrictions that oil impregnated paper insulated cables are widely used to continue. 2, plastic insulated power cable insulation is extruded plastic power cable. Commonly used plastic polyvinyl chloride, polyethylene, cross-linked polyethylene. Simple plastic cable structure, easy manufacturing and processing, light weight crosslinked cable outlets, convenient lay installation, without laying drop restrictions. Therefore widely used for medium and low voltage cables, and replace the cable greaseproof paper impregnated tacky trend. Its biggest drawback is the existence of branches of the breakdown, which limits its use in higher voltage. 3, rubber insulated power cable insulation layer is a rubber with a variety of ingredients, mixing well after extruded conductive wire core, after heated vulcanization. It is a soft spot XLPE cables, flexible, suitable for mobile frequent occasions laying small bending radius. Report power cable "2012 China Power Cable industry depth research report" is the most professional in the field of power cable and the most comprehensive system of in-depth market research reports. The report first describes the background knowledge of the power cable XLPE cable distributor, related concepts including power cables, classification application industry chain structure, industry overview, international market dynamics analysis, dynamic analysis of the domestic market, macroeconomic environment and economic situation analysis impact on the power cable industry, the power cable industry national policy and planning analysis, power cable product specifications, production technology, product cost structure; after these business-related data, summary statistics and analysis, China's power cable production market share, production market share XLPE cables, supply demand shortage import export consumption etc data statistics, also introduced China's power cable 2009--2013 capacity production price cost profit production value profit margins, and finally the use of case The model analyzes the opportunities for risk analysis and investment feasibility analysis of new power cable projects. Overall, this report is the depth of China's power cable industry specifically.
