Kõrgpingeliinid

Kõrgpingeliinid refer to high-voltage power lines used for transmitting electricity over long distances. These lines are a crucial component of the electricity grid, enabling the efficient transfer of power from generation sources, such as power plants, to substations and ultimately to consumers. The high voltage used in these lines significantly reduces energy loss during transmission, making it a more economical and practical method for delivering electricity.

The construction of kõrgpingeliinid involves tall towers or pylons that support thick cables made of conductive materials like aluminum or copper. These cables are suspended at significant heights to ensure safety and prevent contact with the ground or surrounding structures. Insulators are used to prevent the high-voltage current from leaking onto the towers. The specific voltage levels can vary greatly, ranging from tens of thousands of volts to several hundred thousand volts, depending on the distance and capacity requirements of the transmission.

Maintenance of kõrgpingeliinid is essential to ensure reliable power supply and public safety. This includes regular inspections for damage, corrosion, or vegetation encroachment. The design and placement of these lines are also subject to environmental regulations and aesthetic considerations. In Estonia, the management and operation of the high-voltage transmission network, including kõrgpingeliinid, are primarily handled by Elering.
