FIELD: cable accessories.
SUBSTANCE: invention relates to heat-shrinkable coupling for connection of three-core power cables and method of its insulation. Heat-shrinkable connecting cable coupling contains tracking-resistant heat-shrinkable outer protective and inner casings. Tracking-resistant heat-shrinkable outer protective casing comprises an outer insulating layer and an inner adhesive layer with a radio tag in the form of a passive HF microchip with a paper-based rectangular antenna soldered into its structure. Radio tag is oriented by a rectangular antenna along the tracking-resistant heat-shrinkable outer protective casing. Coupling also contains conductor tubes, tape Sealant No. 1, bandage thread, shrinkable gloves, insulating cuffs with glue and connectors, bolts installed in holes of connectors, plates Sealant No. 2, spacer, bandage from glass tape, interphase filler, PVC tape, screen tape, galvanized wire, earthing wire attachment assembly in the form of contact plates “grater”, constant pressure springs, bands from galvanized steel wire and tape Sealant No. 3.
EFFECT: simplified identification of the cable coupling with preservation of high insulating properties of the coupling.
