Diameter calculation for electronic wire processing

The square of the electronic wire is actually labeled as the cross-sectional area of the electronic wire, that is, the area of the circular cross-section of the electronic wire, the department for the square mm. in general, the amount of electricity is when the grid voltage is 220v moments, each square of electronic wire processing of the readings of the power-carrying capacity is about one kilowatt. One, 5 kilowatts, aluminum wire each square can carry electricity 0.6-1 kilowatts. So the power of 1 kilowatt of electrical appliances only need to use a square of copper wire is sufficient. Detailed to the current, short distance power delivery ordinary copper wire per square can carry 3a to 5a current. The premise of heat dissipation is good to take 5a/square mm, not good to take 3a/square mm. the square of the electronic wire, calculating the radius of the electronic wire processed with the formula for the circular area of the calculator: the number of squares of the electronic wire (sq. mm) = perimeter (3.14) × line radius (mm) of the square of the two, 5-square line is: 2.5 ÷ 3.14 = 0.8, and then the square of the line to arrive at 0.9mm, so the 3, 5-square line of line Diameter is: 2 × 0.9mm = 1.8mm. Understand the diameter of the line, the square of the line of reckoning is also used to find the circular area of the formula to reckon: line square = circumference (3.14) × line diameter of the square / 4 cable size is also nominal with the square, multi-stranded line is the sum of the cross-sectional area of each wire. The formula for calculating the cross-sectional area of the cable: 0.7854 × line radius (mm) of the square × number of strands in order to cooperate with more electronic and electrical products to develop the international market, the Division has passed the U.S. UL certification, in line with the ROHS, PAHS, CPSIA, Phthalate, SVHC environmental requirements. In line with the "quality of survival, reputation and development, service first" business philosophy, carry forward the team spirit, and strive to build the company into a high-quality, reasonable price, perfect service advanced enterprises.
