A 70 mm² cable size refers to the cross-sectional area of the conductor, which is 70 square millimeters. This measurement indicates the amount of electrical current the cable can safely carry, with larger cross-sectional areas typically allowing for higher current capacities. It is commonly used in electrical installations for power distribution, especially in industrial and commercial applications. The actual current capacity also depends on factors such as insulation type, installation conditions, and ambient temperature.

Cable size is measured in square millimeters (mm²) to indicate the cross-sectional area of the conductor, which directly relates to its current-carrying capacity and resistance. A larger cross-sectional area allows for more electrical current to flow with less resistance and heat generation, reducing the risk of overheating and improving efficiency. This measurement is crucial for ensuring safe and effective electrical installations that comply with industry standards.
64 amps in less than 100 meter long
1000 mm = 1 m so 70 mm = 70/1000 = 0.07 metres. Simple!
AO paper measures 1189 x 841 mm. Area size therefore 999,949 square mm
10 mm = 1 cm 20 mm = 2 cm 30 mm = 3 cm . . 70 mm = 7 cm
