    STP Model Thermocontracting Cable Coupling Sleeves




    STp model thermocontracting cable coupling sleeves are designed for coupling three- or four-core power cables with impregnated-paper and plastic isolation. They are for use with voltages of up to 10 kV. These sleeves can be mounted either underground or outdoors on vertical cable routings, etc., without limitation of level difference.
    The sleeves contain two thermocontracting gloves, which are made of an insulating compound. The inner surface of each glove is covered by a fusible sealer adhesive. Upon contraction of the gloves, the sealer fills in the cable root's hollows and completely seals the termination point. Cable-core tubes and guards virtually form a new insulation of the conductors at the cable coupling point. All the thermocontracting materials used in the sleeve mounting retain their stress-strain properties and sufficient electric strength (at least 30 kV/mm2) after contraction provided the temperature range does not exceed -50 to +100°C.
    Thermocontracting articles provide complete impermeability and high insulating properties. In addition, they have a high mechanical strength and are resistant to chemical action and environmental effect.
