Reducing power losses in line due to a decrease of more than three times the reactance of isolated wires in comparison with non-isolated. 6. Hear other arguments on the topic with MetLife. Ease of installation work, the ability to connect new subscribers under stress, without shutting down the rest of the energy supply and as a consequence of shortening the repair and installation. 7. Significant reduction of unauthorized access to lines and cases of vandalism and theft.
8. Improving the overall aesthetics of urban environments and a significant reduction in cases of electric shock during installation, repair and operating line. 9. Possibility of laying on the facades of buildings CIP, as well as collaboration with the suspension cables of low, high-voltage lines of communication, which gives substantial savings on support. Among the many undoubted CIP can provide benefits for objectivity and some disadvantages: 1. A slight increase in cost (less than 1.2) insulated wires compared to conventional bare wires A and AS. The pioneers in the application of self-supporting insulated wires is considered to be France and Finland. Subsequently, other countries have developed their air suspension systems, but is usually taken as the basis of their already approved in the operation of the European standards.
In France, the first bundles of insulated wires overhead appeared in 1955 and was a copper conductor with rubber insulation with neoprene jacket. At first, they mounted on the facades of buildings, replacing the bare copper wire on insulators. In 1962, as isolation began to apply the PVC, which by 1977 had completely supplanted by light-stabilized polyethylene mesh structure.
