AWG standard

Standardization has always been one of the requirements in the production of all kinds of goods, the most basic advantage of which is the uniformity and coordination of the desired products, and at the same time, the separation of its different models for the supply and use of customers. The cable industry is not exempt from this and in the past years, different standards have been introduced by different countries to the world, and in this article, we are going to review the widely used AWG standard.

Standard (American Wire Gauge) AWG It is an American measurement system and Wire Gauges are used in the field of measuring and classifying the diameter or cross-section of the wire, solid conductive, flexible conductive, and non-metallic wires; These measuring standards help to know the carrying capacity of electric current or the value of its conductivity by using the diameter or cross-sectional area of ​​the wire. In addition to the metric standard, Electro-Sim Hedayat Company is one of the pioneers in the production of various types of specialized cables with this standard. Some call AWG cables under the title of special cables, while it differs only in terms of the sizing standard, and all cables can be described based on this standard.AWG standard

Standard Brown & Sharpe wire gauge

This standard, which is also known as the Brown & Sharpe wire gauge, includes all cables and different classes used, and each step changes as a logarithmic relationship. Actually, the roots of using this standard go back to the wire and cable production process in the factory. During the stretching and thinning stages of the wire, the wire passes through several molds. The numbers of this gauge are based on the number of molds used during the wire thinning process until the final stage. A higher number means more thinning dies and therefore finer wire. Therefore, unlike metric standards, the larger the AWG standard number, the smaller the wire diameter.

In the discussed standard for stranded wires, the sizes start from 4 zero (0000) and continue to 40, thus this standard contains 44 sizes. The gauge value indicates the electrical resistance of the wire, its diameter, and other physical characteristics of the wire. The characteristics of the material used in the wire also affect the AWG value. The electrical conductivity of aluminum is 61% of copper. Therefore, the electrical resistance of an aluminum wire is equal to that of a copper wire whose AWG value is two numbers smaller than that of aluminum.

The thickness of the wire also makes a difference in the AWG value. The reason for this is the space between the strands of the wire, which makes up about 10% of the cross-section of the wire. Therefore, the wire should be about 5% thicker than the wire. taken to have the same resistance. AWG sizes from 0000 to 36 are considered for the emitting wires.

Spray wires are identified by three numbers:

Total AWG value

AWG size for each strand

Number of strands of wire

The number of strands and the AWG of each strand is separated by a slash (/).

For example, an AWG 22 wire feeder that has 7 strands of wire and each strand is AWG 30 is displayed as follows:

AWG 22 7/30

Also, in wire wires, AWG refers to the diameter of the wire, and in the case of insulated wires, it refers to the cross-sectional area of the wire.
