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.
An anchor portal or H-frame tower is a gantry structure supporting overhead power lines in a switchyard. Their static function is similar to a dead-end tower . Anchor portals are almost always steel -tube or steel-framework constructions.
The poles at the end of a straight section of utility line where the line ends or angles off in another direction are called dead-end poles in the United States. Elsewhere they may be referred to as anchor or termination poles. These must carry the lateral tension of the long straight sections of wire. They are usually made with heavier ...
Single helix earth anchors Guyed mast anchor. An earth anchor is a device designed to support structures, most commonly used in geotechnical and construction applications. Also known as a ground anchor, percussion driven earth anchor or mechanical anchor, it may be impact driven into the ground or run in spirally, depending on its design and intended force-resistance characteristics.
Guys are particularly needed on dead-end (anchor) poles, where a long straight section of wire line ends, or angles off in another direction. To protect the public against faults that might allow utility guy cables to become electrified, they usually have a ceramic strain insulator ("Johnny ball") or a fiberglass strain insulator inserted near ...
Anchor steel pole (flag) 6 horizontal dead-end insulators (line 1 on upper 3 and line 2 on lower 3) made of 21-22 porcelain discs with 6 horizontal pole-mounted porcelain insulator at the center. Some anchor poles can also have a custom crossarm and ignoring the one designed on the pole itself.
