    SS Model Lead Cable Coupling Sleeves




    SS model lead cable sleeves are designed for coupling cables with a conductor section between 10 and 240 square mm, with an impregnated-paper insulation and with an insulation impregnated with non-drop mixture, in aluminium or lead sheath, with or without serving. They are for use with voltages ranging from 6 to 10 kV at 50 Hz. They are laid underground, in tunnels, bores and other cable structures, and are designed for use in any climatic conditions where the relative humidity does not exceed 98% at a temperature 35°C. The sleeves can be used in water provided they are protected with special casing.
    The basic element of the coupling sleeve is a lead tube that is rounded on both sides of its contact with the metal cable sheath and that is soldered to it. The conductor coupling point is insulated with paper reels and rolls. The inside of the lead tube is filled with an asphalt mortar or an oil-colophony mixture, which is poured through the holes cut beforehand. The sleeve is then placed into either protective housing KZP (plastic housing) or KZCh (iron housing).
    The service life is at least 25 years.
