Types of Power Lines

Anchor and Angle Tension Towers
Anchor and Angle Tension Towers

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.

Coaxial Cable
Coaxial Cable

There is no device to run your cable signal over power. There would be no way to contain all the frequency from getting out of the power cabling or keeping unwanted signals from getting in and causing interference - that is why shielded coax is used.

Communications Cable
Communications Cable

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).

Guyed Towers
Guyed Towers

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.

Lattice Steel Towers
Lattice Steel Towers

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.

Metallic Sheathed Cable
Metallic Sheathed Cable

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.

SIngle and Double Circuit Towers
SIngle and Double Circuit Towers

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.

Suspension Straight Towers
Suspension Straight Towers

These are used where a transmission line continues in a straight line, or turns through a small angle. In other cases, a tension tower (C or D Towers) is used. An example of a suspension tower in the Philippines.

Terminal Transmission Towers
Terminal Transmission Towers

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.
