Dead-end towers may use earth anchor cables to compensate for the asymmetric attachment of the conductors. They are often used when the power line must cross a large gap, such as a railway line, river, or valley. Dead-end towers may be constructed of the same materials as other structures of the line.
One end of the guy is attached to the structure, and the other is anchored to the ground at some distance from the mast or tower base. The tension in the diagonal guy-wire, combined with the compression and buckling strength of the structure, allows the structure to withstand lateral loads such as wind or the weight of cantilevered structures.
The power lines are attached to the pole by horizontal strain insulators, either placed on crossarms (which are either doubled, tripled, or replaced with a steel crossarm, to provide more resistance to the tension forces) or attached directly to the pole itself. Dead-end and other poles that support lateral loads have guy-wires to
Dead-end structures support the full weight of the conductor and also all the tension in it, and also use strain insulators. Structures are classified as tangent suspension, angle suspension, tangent strain, angle strain, tangent dead-end and angle dead-end. [15] Where the conductors are in a straight line, a tangent tower is used.
The conductor is suspended at the bottom end of this string while the top end is secured to the cross-arm of the tower. The number of disc units used depends on the voltage. Strain insulator - A dead end or anchor pole or tower is used where a straight section of line ends, or angles off in another direction. These poles must withstand the ...

A gin pole in use loading logs A gin pole used to install a weather vane atop the 200-foot steeple of a church Roof trusses being assembled with gin poles. A gin pole is a mast supported by one or more guy-wires that uses a pulley or block and tackle mounted on its upper end to lift loads. The lower end is braced or set in a shallow hole and ...
Some newer anchor steel poles can have polymer composite dead-end insulator. Irregular variant has 3 horizontal dead-end insulators on a steel crossarm and another 3 arranged in a vertical pattern, has vertical insulator mounted on one side of a crossarm, at the center are 1-2 insulators, and on the pole's top segment is another steel crossarm ...
