METHOD FOR MANUFACTURING TERMINATION DEVICE OF MULTIPLE-CORE HEATING CABLE (VERSIONS) Russian patent published in 2010 - IPC H02G15/04 H01B7/17 

FIELD: oil and gas production.

SUBSTANCE: characteristic property of the offered group of inventions is as follows: for manufacturing a protection assembly, a protection tube is put on a terminal of the cable; the first thermocontracting glove is put on the stripped cores with terminating each core on a separate finger of the specified glove; the core ends terminated on the fingers of the thermocontracting glove are arranged in a metal bushing with escaping the cores outside; the second thermocontracting glove is put one the cores escaped from the metal bushing and thermocontracted; the metal bushing put on earlier is lowered on a zone of the thermocontracting second glove, a protection metal cup is attached to the end of said bushing; the first glove is moved with an overlap on the bushing and thermocontracted; according to the first version, length of the protection tube exceeds that of each thermocontracting tube; according to the second version, length of the protection tube is less than the thermocontracting tube.

EFFECT: higher reliability of hermetic sealing of the manufactured termination devices and higher degree of bruise resistance.
