OREANDA-NEWS. A group of KEGOC's employees patented an innovative invention of “suspension tower guy wire anchoring assembly located above the ground surface”

The invention will prevent corrosion of the buried metal attachment parts by brining them above the ground, and reduce the cost of audit of the suspension towers of ultrahigh voltage transmission lines (1,150 kV).

Currently, 1150 kV suspension towers use guy wires attached to anchor plates buried about 3 meters under the ground level.

Affected by the aggressive environment (humidity, salt, and electric current), the attachment joints and U-bolts suffer from intensive mechanical and electrochemical corrosion, which can lead to reduced stability and collapse of the tower type POG-1150-1 weighing over 20 tonnes.

The anchoring assemblies under the ground shall be audited every 6 years: they shall be excavated, which is costly. It should be noted that one 1,150 kV tower has 4 anchoring assembly units, and one overhead line section may consist of more than 200 towers.

The invention provides a foundation structure with the guy wire anchoring assembly located above the ground.

Such design prevents corrosion of the metal parts of the anchor, significantly extends its service life, simplifies the audit process, and significantly reduces the maintenance costs.

Innovative patent No.27514 registered in the State Register of Inventions of Kazakhstan on 24 September 2013.
