SYSTEM OF LIGHT ENCLOSURE OF HIGH-VOLTAGE POWER TRANSMISSION LINES Russian patent published in 2025 - IPC H02G1/02 F21S8/06 

FIELD: electricity.

SUBSTANCE: invention relates to electric lighting devices and can be used in electric power industry as marking lights of wires of high-voltage power lines for designation of object dimensions, in order to ensure the safety of aircraft flights in areas of aerodromes, air routes, as well as areas the surface of which rises above the ground. Disclosed is a system for light enclosure of high-voltage power transmission lines, consisting of a gas-discharge lamp, an antenna, insulators and fasteners. Distance from the antenna to the phase conductor is selected within range of 300 mm to 400 mm, for a power transmission line for rated voltage of 500 kV, the length of antenna is 3 m, for lines of 330 kV, 220 kV and 110 kV is 6 m, and for 35 kV lines is 8 m. One electrode of the lamp is connected to the phase wire by a bushing, and the lamp and the antenna are fixed on a common insulating suspension using a two-plane universal ram clamp, consisting of two parts, having four holes when assembled, two of which are located above and below the connector, and two through holes – on the side. Upper hole and two side holes are located in the same plane, the lower hole is in the plane perpendicular to the plane of the other three holes, the diameter of the upper hole is matched with the diameter of the rod of the insulator end terminal, and of the lower hole – with the cable diameter.

EFFECT: reduction of overall dimensions and weight of the system, simplification of installation of the device on a phase conductor, increase of its mechanical strength and provision of the possibility of its application on power transmission lines with rated voltage of 35 kV.
