What Is A Transmission Line ?

Transmission Line is a conductor which is capable of transmitting energy from one point to another. Some examples of transmission lines include electric power lines, wiring, and coaxial cable. Depending on the project, there are a number of characteristics which a transmission line must have in order to function effectively. For large-scale products and systems, specialty products may need to be engineered and designed to meet the specific need.

Several types of energy can be transmitted over a transmission line. Electrical power is a familiar example for many people, but these lines can also carry acoustic energy and electromagnetic energy which may include light. Transmission Line can be designed to carry large quantities or small ones, and can operate in a variety of conditions including extreme temperatures and pressures, along with wet environments. The lines are usually rated to indicate what kind of energy they can transmit and in what volume, with people selecting transmission lines which are rated well above the intended use to increase safety.

What is Overhead power line & How It Came.

DP Structure

DP Structure

 

An Overhead power line is an electric power transmission line suspended by towers or utility poles. Since most of the insulation is provided by air, overhead power lines are generally the lowest-cost method of transmission for large quantities of electric energy. Towers for support of the lines are made of wood (as-grown or laminated), steel (either lattice structures or tubular poles), concrete, aluminum, and occasionally reinforced plastics. The bare wire conductors on the line are generally made of aluminum (either plain or reinforced with steel, or sometimes composite materials), though some copper wires are used in medium-voltage distribution and low-voltage connections to customer premises. A major goal of overhead power line design is to maintain adequate clearance between energized conductors and the ground so as to prevent dangerous contact with the line. Today overhead lines are routinely operated at voltages exceeding 765,000 volts between conductors, with even higher voltages possible in some cases.

About Disconnecting Switch.

Disconnecting Switch

Disconnecting Switch

A Disconnect switch is a switch which has the capability to interrupt power to an electrical circuit or to a group of electrical circuits. Disconnect switches are used in a wide variety of settings, and are primarily employed as safety devices which de-energize circuits so that people can work on them safely. Electrical safety devices are only as useful as their maintenance and the surrounding safety procedures, and a disconnect switch must be used properly in order to be effective.

A Pin Insulator

Pin insulator

Pin insulator

A Pin insulator consists of a non-conducting material such as Porcelain, Glass, Plastic, Polymer, or Wood that is formed into a shape that will isolate a wire from a physical support (or “pin”) on a telegraph, utility pole or other structure, provide a means to hold the insulator to the pin, and provide a means to secure the conductor to the insulator. By contrast to a strain insulator, the pin insulator is directly connected to the supporting pole. The earliest pin insulators predate the strain insulator and were deployed before about 1830. Pin insulators continue in production with manufacturers worldwide.
