Oil cable OLS 4B
anticorrosive materials
Description
Cable oil OLS 4B – kabelnyoe oil generated from the waxy crude oils using hydrocatalytic processes. Contains additives providing stability during aging with exposure to the electric field.
Applications
Oil OLS 4B is used as the impregnating and insulating medium in the oil-filled power cables with voltage paper insulated 1-35kV. Power cables of the type used for electric power transmission and distribution in stationary equipment in areas with temperate or cold climates.
Oil OLS 4B stably retains the electrical properties of prolonged heating, has good dielectric properties, characterized by high resistance to a gas ionized by the electric field
