Joints for paper insulated cables up to 35 kV

摘要

The invention relates to the cable industry and the electrical industry can be used to connect the power cable construction lengths paper insulated voltage of 35 kV. For insulation sleeve used paper rolls and rolls of trapezoidal impregnated maslokanifolnym composition. By reinforcing the outer surface of rolling superimposed screen: by leveling cones - tinned copper conductor, a cylindrical portion underwinding - foil with a substrate of semiconducting paper. Reinforcing preroll is sealed in a lead or brass coupling housing, consisting of two coupling halves. Sealingly coupling halves are soldered to each other and to the metal sheath of the cable ends to be connected. Tightly-knit body maslokanifolnym poured potting compound. Using the clutch allows to increase the dielectric strength of seats cable connections.
