Method of manufacturing insulated electric power cables |
摘要 |
Insulated electric power cables comprising a cured insulating material applied over a conductor and a layer of plastic compound comprising 100 parts by weight of a thermoplastic resin and 5-70 parts by weight of calcium oxide as a moisture-absorbing agent, overlying the insulating material and, optionally, lying between the conductor and the insulating material. The presence of calcium oxide serves to absorb steam before it penetrates into the insulating material through the layer of plastic compound being cured by steam, whereby the cured insulating material is free of microvoids and possess good insulation characteristics.
