In the world full of electrical devices, what keeps us connected is the wire and cable.
Choosing the best kind or type of conductor which is suited for your need is time consuming, but don’t worry because we have gathered this information in the following content.
electrical wire conductor
The term "conductor" refers to a specific kind of metal that is capable of allowing an electric current to flow through it.
Metals such as copper and aluminum, as well as alloys of those two elements, are typically used to construct the electrical conductor.
When a potential difference is applied across a group of atoms in an electrical conductor, the electrical charges flow from one atom to the next in the conductor.
Wire is the most common form that the electrical conductors take when they are put to work.
When deciding the type of conductor to use, it is important to take into account a number of different criteria, including tensile strength, fatigue strength, corona loss, local conditions, and cost.
In most cases, the electrical conductor that is employed in the process of power transmission is stranded.
When compared to a single wire with the same cross-section area, stranded conductors offer a greater degree of flexibility and greater levels of mechanical strength.
The center wire of a stranded conductor is often encircled by consecutive layers of wires in a stranded conductor, each layer containing 6, 12, 18, 24, etc. wires.
Electrical wire conductor type
The electrical and power transmission wire and cable are divided into different groups, considering the type of material that is used in the conductor.
Conductors made of steel-cored copper, hard-drawn aluminum, and hard-drawn aluminum with a steel core are the most frequent types used in a power plant.
The following provides a detailed explanation of several of the more significant types of conductors.
Conductor made of hard-drawn copper These particular kinds of conductors have excellent tensile strengths.
A strong electrical conductivity, a long life, and a high scrap value are all characteristics of this material.
It is most suited for use in distribution work, which typically involves a greater number of spans and tappings.
Conductor made of Cadmium and Copper By adding roughly 0.7 to 1.0 percent cadmium to the copper, the tensile strength of the copper is raised by approximately 50 percent; however, the conductivity of the copper is lowered by approximately 15 to 17 percent.
Due to the fact that it has a higher tensile strength, the conductor may be installed over longer spans while maintaining the same amount of sag.
This conductor has many advantageous properties, including the capacity to be easily joined, increased resilience to atmospheric conditions, improved resistance to wear, simple machinability, and more.
The temperature at which copper anneals and becomes softer has also been raised, and the effects of temperature on stresses have been reduced.
The variation in sag that is caused by shifts in load and temperature is reduced as much as possible.
Conductor Made of Steel-Cored Copper (SCC) Copper strands are wrapped around steel in steel-cored copper conductors, which can have one or two layers of copper strands around them.

Aluminium Conductor Steel Reinforced When it comes to their mechanical strength, aluminum conductors in their purest form are not suitable for the building of long-distance power lines.
This shortcoming in strength can be remedied by incorporating a steel core into the conductor.
[Compensation] The term "steel-cored aluminum conductor" (SCA) or "aluminum conductor steel reinforced" is used to refer to this type of conductor (ACSR).
The center core of the ACSR conductor is made up of seven steel strands, and on either side of that core are two layers consisting of 30 aluminum strands each.

There are some factors that determine the price of wires such as material, size, insulation and labeling.
Conductor made of Phosphor Bronze Phosphor bronze is a type of conductor material that is typically utilized for very long spans, such as those that cross rivers.
