Description

Technology Field

[0001] The present invention relates to a protection device for power distribution lines in mountainous areas, and more specifically, to a protection device installed on a utility pole that protects and supports cables of overhead power distribution lines, thereby protecting the cables to prevent damage to the cables by external forces and supporting the cables to prevent sagging, thereby preventing the transmission of cables due to sagging, and preventing safety accidents caused by leakage current that occur when the sheathing of sagging cables is peeled off or damaged due to friction as they move by the wind, and by supporting the power distribution line through elasticity, it improves supporting and fixing strength and cushions the transmission of shocks. Background Technology

[0003] Generally, extra-high voltage (765 kV, 345 kV, 154 kV) electricity produced at power plants, etc., is supplied to substations via transmission lines, and at substations, the extra-high voltage is lowered to 22,900 volts (phase voltage 13,200 volts) and supplied to general buildings or factories through distribution lines, and some of the extra-high voltage supplied to substations is lowered to an easy-to-use voltage of 220 / 380 volts through pole-mounted transformers and phase-mounted transformers attached to utility poles, and supplied to houses, shops, small factories, etc.

[0004] Such a transformer is a device that converts an AC power source supplied to one winding into an AC power source of a different voltage to another winding by means of electromagnetic induction, and is composed of windings forming at least two electrical circuits, an iron core forming a common magnetic circuit, and insulating materials such as insulating oil.

[0005] Transformers can be classified according to their place of use into small transformers, pole-mounted transformers installed on utility poles, and power transformers installed in power plants or substations. Additionally, they may be classified according to their purpose of use into test transformers, grounding transformers, rectifier transformers, electric furnace transformers, and explosion-proof transformers.

[0006] These transformers are installed on utility poles or on the ground to supply power to multi-unit housing and the like through distribution lines, which are cables.

[0007] However, conventional power distribution cables have the problem of sagging due to their own weight. Due to continuous sagging, the cables may break, or the sheathing may be peeled off or damaged as the sagging cables are moved by the wind, leading to persistent issues such as electrical leakage or safety accidents caused by leakage.
