The anchor must be adequate to resist the maximum tensile load of the guy wires; both the dead load of the tension of the wire and the maximum possible live load due to wind. Since the guy wire exerts its force at an angle, the anchor has both vertical and lateral (horizontal) forces on it.
Telegraph pole with spars, insulators and open wires on a now decommissioned Railway Pole Route, Eccles Road, Norfolk, United Kingdom. A pole route (or pole line in the US) is a telephone link or electrical power line between two or more locations by way of multiple uninsulated wires suspended between wooden utility poles. This method of link ...
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 lateral (horizontal) tension of the long straight section of wire. To support this lateral load, strain insulators are used.
A guyed radio mast. A guyed mast is a tall thin vertical structure that depends on guy lines (diagonal tensioned cables attached to the ground or a base) for stability. The mast itself has the compressive strength to support its own weight, but does not have the shear strength to stand unsupported or bear loads.
Dead-end ("anchor") towers. A dead-end tower (also anchor tower, anchor pylon) [1] is a fully self-supporting structure used in construction of overhead power lines.A dead-end transmission tower uses horizontal strain insulators at the end of conductors.
By wrapping electrical wires around the knob, and securing them with tie wires, the knob could be used to securely and permanently anchor the wire. The knobs separated the wire from potentially combustible framework, facilitated changes in direction, and ensured that wires were not subject to excessive tension.
