Impregnated Paper Insulation

Power cables with oil-impregnated paper insulation. The insulation layer is formed by spirally wrapping a certain width of cable paper on the conductive wire core, and impregnated with an impregnating agent after vacuum drying. According to the viscosity and pressurization method of the impregnating agent, oil-impregnated paper insulated power cables can be divided into 6 types. ?Viscous insulated cables are power cables whose insulation layer is oil-impregnated paper. The insulating layer is formed by spirally wrapping a certain width of cable paper on the conductive wire core, and impregnated with an impregnating agent after vacuum drying. According to the viscosity and pressurization method of impregnating agent, oil-impregnated paper insulated power cables can be divided into 6 types. Dipping stickiness. The impregnating agent is generally made of a mixture of bright oil and rosin (bright oil accounts for about 65-70%, and rosin accounts for about 30-35%). Many countries use synthetic resin (such as polyisobutylene) instead of rosin, and mix it with bright oil to form low-voltage cable impregnating agent. Viscous impregnated paper insulated power cables can be divided into insulated type (all-inclusive type) and phase-separated shielded (lead-clad) type according to the structure. The insulated cable is a paper insulation (phase insulation) layer with a certain thickness wrapped around each conductive core, and then the three insulated cores are twisted together and reassembled.
