L.T And H.T Stay Set is a hardware assembly used in electrical power distribution systems for providing support and stability to utility poles or towers. It is designed for tolerating the mechanical forces and tension applied by the overhead conductors. The stay set typically includes a steel wire or stranded conductor, guy grips, insulators, and anchoring hardware. L.T stay set is used for low voltage distribution lines, while H.T stay set is employed in high voltage transmission and distribution systems. It ensures the proper alignment and positioning of the poles or towers, to prevent excessive movement and maintain the integrity of the power distribution network.
