Suspension angle towers are built when it is necessary for the route of the electrical current to turn. These angle towers are usually designed so that the axis of the cross-arm bisects the angle of the conductors. This is the most efficient way to use the tower. Anchor and Angle Tension Towers. Anchor and angle tension towers are used to sectionalize the routes.
Power-line communication (PLC) carries data on a conductor that is also used simultaneously for AC electric power transmission or electric power distribution to consumers. It is also known as power-line carrier, power-line digital subscriber line (PDSL), mains communication, power-line telecommunications, or power-line networking (PLN).
The most common types of direct burial cable used in residential projects are underground service entrance (USE) and underground feeder (UF). Type USE cable is usually black and is most often used for buried lines that bring the power from the utility's transformer to individual houses.
A guy-wire, guy-line, or guy-rope, also known as simply a guy, is a tensioned cable designed to add stability to a free-standing structure. They are used commonly in ship masts, radio masts, wind turbines, utility poles, fire service extension ladders used in church raises and tents.
A lattice tower is a framework construction made of steel or aluminium sections. Lattice towers are used for power lines of all voltages, and are the most common type for high-voltage transmission lines. Lattice towers are usually made of galvanized steel.
Non-metallic sheathed cable, also called NM cable or Romex, after the popular brand name, is a flexible electrical cable with a plastic outer coating. That's the non-metallic sheath. Inside the sheath are two or more insulated wires and usually a ground wire.
In 2004, Power Line was named Time magazine's first-ever "Blog of the Year." When AOL added blogs to their news website in 2007, Power Line was one of the five blogs included. A 2007 memo from the National Republican Senatorial Committee described Power Line as one of the five best-read national conservative blogs.
Single circuit transmission line takes only one set of power lines from one destination to other. Double circuit transmission lines take two different set of power lines which are not interconnected - the destination and source may be the same or can also be different.
A transmission tower or power tower (electricity pylon in the United Kingdom, Canada and parts of Europe) is a tall structure, usually a steel lattice tower, used to support an overhead power line. They are used in high-voltage AC and DC systems, and come in a wide variety of shapes and sizes.
