CABLE END SEALING DEVICE RESISTANT TO PRESSURE AND TEMPERATURE Russian patent published in 2023 - IPC H02G15/23 

FIELD: electrical engineering.

SUBSTANCE: device consists of conductors in the form of metal cores (1) made of heat-resistant metals of the chromel-alumel system. Each core is enclosed in mineral insulation (2) made of magnesium oxide enclosed in a metal sheath (3) made of heat-resistant steel. The body (5) is designed as a cylinder made of heat-resistant steel, with a recess through the holes in the base of which metal shells (3) are passed. The base of the housing (5) is coated on the inside with a metal solder (6) that hermetically covers the metal shells (3). The space inside the metal shell (3) from the side of the free end is filled with solder glass (4).

EFFECT: resistance to high pressure and temperature while simplifying the design implementation of the device.
