摘要:
A high voltage cable includes a fiber core, a first layer of electrically relatively non-insulative polymer, a second layer of electrically relatively non-conductive polymer, a third layer of electrically relatively non-insulative polymer, a fourth layer including a braided wire shield, and a fifth layer including a solvent- and abrasion-resistant polymer jacket.
摘要:
A process for the production of flexible impregnated protective, auxiliary and insulating materials on a fibre basis for electrical purposes by the application of an impregnating agent to the material to be impregnated, followed by curing, characterised in that a solvent-free impregnating mass containing one or more olefinically unsaturated, radically polymerisable polyesters, which contain one or more radically polymerisable monomers as reactive diluents, one or more plasticizing agents and optionally one or more peroxide-free radical initiators is applied to the material to be impregnated and curing is then carried out with high energy radiation and optionally by further heating.
