Primary utility wiring uses an ACSR cable, (Aluminium Conductor Steel Reinforced). The multiple strands of aluminum wires are wound around a center steel cable. The steel center is used to allow longer spans between poles or towers. Ordinary aluminum wire can not be long spanned because its weight would break the wire. All other high voltage wiring is done with different insulation thicknesses dependant upon what the voltage is. The higher the voltage the thicker the insulation. Insulation of the wires stops when the conductors carry kilo voltages usually above 5000 volts.

How do you test a closed circuit?
we can make an open circuit by disconnecting the wire or break the circuit and a closed circuit is made by connecting all wires with the contents of the circuits.
What are high voltage gloves?
High voltage gloves, also known a gauntlets, are gloves worn by utility line men. There are two parts to the gloves. The inner pair are made of a high dielectric rubber numbered from 00 to #4 which covers voltage ranges from 500 to 36000 volts. The outer pair are made of leather. They are used to stop perforation and scratch cuts of the inner gloves from wires end perforation. Before the gloves are used they have to be tested by the person that is using them. Every year they have to be sent to a testing laboratory to be tested with high voltage to make sure that they still maintain their voltage insulation number rating. If the gloves fail this test the gloves are destroyed and new ones have to be purchased. These gloves are for line men safety and are worn even when the high voltage system is de energized.
Is China a insulator?
China is, or used to be (the current material may be some made made material) china on power lines. The separators were made of china to insulate them.
What is electrical resistance used in glass for?
High voltage transmission line insulator are also made of glass.
Can heating devices be made by passing an electric current through a conductor of high resistance low resistance high conductivity low conductivity?
Heating is caused by current flow. Certain types of wire like tungsten emit more heat than other types. Lower resistance means higher current for a fixed voltage per Ohm's Law. So the efficiency of heating with electricity depends on the material of the conductor, the operating voltage and the resulting current. In most instances this will be a low resistance with high conductivity.
How is electric current of high voltage made suitable for household consumption?
The voltage is reduced, in transformers.
How electric current of high voltage made suitable for household consumption?
The voltage is reduced, in Transformers.
Why are electric wires don-not made of rubber?
Obviously, rubbers are not conductors. Wires are commonly made of copper.
Which magnet made by an electric current flowing through wires?
Electromagnet.
What is the solute and solvent in dilute hydrochloric acid?
Give reasons. Electric wires in electric posts are made of aluminum.
Why are birds not harmed by the large amount of electric current passing through the wires?
i think (not sure) their wires are made of insulator.......
How is electric energy transferred?
Usually through wires. Over long distances, it is usually transferred in the form of AC (alternating current), since in that type of electricyt it is easy to increase or decrease the voltage through transformers.
What kind and type wire can be used to wire an electric cook stove?
The wires must first be heat resistant. For that the best wires that can be used are wires made up of superconductors.
How do you test a closed circuit?
we can make an open circuit by disconnecting the wire or break the circuit and a closed circuit is made by connecting all wires with the contents of the circuits.
How are electric cars made?
Electric cars that are made for production are made in assembly lines. For prototypes the individual pieces may be made separately. The major components needed in the electric cars are the batteries, motor, drive train, voltage controller, and battery charger.
How are circuits made?
circuits are made by connecting wires to an electrical resource and the electricity travels through and powers your electric device.
What is a Statiscope made by Minerallac Electric Company in Chicago Illinois?
The statiscope is primarily designed to detect the electric field of a high voltage conductor, whether bare orinsulated. The end of the statiscope just has to come near the conductor, it does not actually have to come in contact with the conductor. In fact, it is probably best that it doesn't unless you know just how high the voltage is. When the presence of a high voltage field is detected, the neon tube will glow. The statiscope should be tested both before and after use by using a known energized high voltage circuit. That is done to be sure that the statiscope has not failed and that it will give, and has given, an accurate display. (One handy use for the statiscope is for checking the presence of proper voltage to auto spark plugs)
