Used for electrical power or electrical signals transmission as part of equipment operating under high pressure and temperature and aggressive media in oil and gas and geophysical equipment. These devices are designed for operation in AC, DC and pulse current circuits with frequency up to 3 MHz.

Seal leads for geophysical instruments of oil and gas complex are designed for connecting sections of electric communication or power supply line and sealing the place of its passage through the element of downhole instrument construction.

Sealed cable entries are produced by injection moulding or compression moulding from composite materials based on polyetheretherketone or fluoroplastic. The cable entries are produced from copper, copper alloys or stainless steel and have a special fixing in the hermetic conduit body.
