What is a circular mile?

Circular miles (cmil) is the degree of cross -sectional surface of the cable. One circular mile is a very small area. If the circle has a diameter that is exactly a thousand times less than 1 inch (0.03 m), the area of ​​this circle is 1 circular mile. If international projects are carried out, there are agreements on which standards will be forced. When selecting the standard, the principles involved in different cable size specification should be understood. For people, it is a good idea to know how to convert the size of the wire in different units. There are conversion tables to easily convert circular mills to an American wire breakup (AWG) to a square millimeter and other measuring units.

Circular miles is often a choice for specification of wires and cables. There are links to the English system and a metric system to cross -sectional areas of wires and cables. The circularil refers to the circle area with a diameter of 0.001 inches (0.0254 mm), while the reference to the metric system is a square millimeter. A million circular mills is equivalent to about 0.7854 fourRecent thumb (1.99 square cm).

The

circular mile refers to the size of the cable or the cable cross -sectional surface. For electrical cables, there could be a single circular cross -section or several smaller cables to form a larger cable that is referred to as a stuck cable. 1,000 fixed cables of cmil and 100 cm x 10 Cut cable can have the same electrical capacity, but various mechanical specifications. Insulation is another thing for electrical cables. Whether the cable is to meet the insulation on 300 volts AC current (VAC), for example or 1,000 volts, a direct current (VDC) must be thoroughly studied.

Electric charges for powered cable travel on the right of the aforementioned cross -sectional area, which is very similar to vehicles passengers at right angles to the width of the highway. The wider the highway, the more vehicles they can travel for a unit of time. On the electrical cable, the wider or larger the cross -sectional area, the moreElectric charge can travel per unit of time. In other words, the greater the cross -section, the greater the assessment of the ampere.
