What is high tension wire?

High tension wire is the wire used for transmission of electrical energy having high voltage over long distances. They require to have low resistance to minimise heat losses and be able to withstand high voltages.

Whats the meaning of high tension?

high-tension in American English (ˈhaiˈtenʃən) adjective. Electricity. subjected to or capable of operating under relatively high voltage.

Why are they called high tension wires?

high-tension in Electrical Engineering You need very high voltage for transmission on high-tension power lines. A high-tension cable carries more than 1000 Volts between conductors and 600 Volts between conductors and ground.

What are the characteristics of a high tension wire?

A high tension wire has a low resistance and large surface area.

What is a safe distance from high tension electrical wires?

As per the Indian Electricity Act, buildings should maintain a horizontal distance of 1.2 metres from 11kV lines and 4 metres from 66kV lines.

What is the range of high voltage?


IEC voltage range AC RMS voltage (V) DC voltage (V)
High voltage > 1 000 > 1 500
Low voltage 50 to 1 000 120 to 1 500
Extra-low voltage < 50 < 120

How far from high tension wires is safe?

Possible Safety Distances to Consider for EMF Sources

Safety Distances from Various EMF Sources: Possible EMF Safety Distances To Consider for Common EMF Sources ELF Magnetic Fields
Power Lines
High voltage power lines (on metal towers) 700 feet
Neighborhood distribution power lines (on wooden poles) 10 to 200 feet

What is the voltage of high tension power lines?

Typical voltages for long distance transmission are in the range of 155,000 to 765,000 volts in order to reduce line losses. A typical maximum transmission distance is about 300 miles (483 km). High-voltage transmission lines are quite obvious when you see them.

Can high tension wires be removed?

We suggest you to make a written complaint to Power Transmission Department, MCD, to remove the high tension wires. In case they fail to remove the wires, then you may approach to the Court by filing writ petition against MCD.

Can we build house under high tension wire?

“Construction right under high tension wires is prohibited. However, many buildings in the city are either directly under high tension wires or in close proximity, leading to fatalities,” he said.

What is a high tension cable?

High tension leads or high tension cables or spark plug wires or spark plug cables are the wires that connect a distributor, ignition coil, or magneto to each of the spark plugs in some types of internal combustion engine .

What is high tension line?

A low-tension line is a low voltage line and a high-tension line is a high voltage line. In India LT supply is of 400 Volts for three-phase connection and 230 Volts for single-phase connection. High tension or HT supply is applicable for bulk power purchasers who need 11 kilo-Volts or above.

What is smooth wire fencing?

As the name implies, the wire is smooth with no barbs present. Smooth wire used in combination with a fence charger is a common, inexpensive fencing option to contain horses and other animals prone to entanglement. Smooth wire is less likely to injure animals which become entangled or rub up against the wire.
