FIELD: electrical engineering. SUBSTANCE: volume of insulation material having capability to expand is limited and sealed. Low heat transfer through cutting is ensured in addition. Clamps with recessions forming spaces are located outside each flange. Sealing elements in the form of plastic insulation temperature stable material overlapping clearance along cable are located in these spaces. Flanges are connected to body through temperature stable gasket. EFFECT: improved sealing properties. 14 cl, 7 dwg
