云顶集团网址 2.5 square wire load

云顶集团网址 The load of the wire depends mainly on the current and also on the voltage level. Under normal circumstances, the safe carrying capacity of 1mm2 below 50A is 6A, the safe carrying capacity of 1mm2 under 50A is 5A, and the safe carrying capacity of 1mm2 above 100A is 2.5a. That much square of copper cable is enough to figure out the current. According to the three-phase ac formula: P=1.732*U*I*cos, cos is the power factor, choose 0.8; This is the formula for calculating the three-phase power. Single-phase: P=U*I*cos, cos is power factor power factor is 1 for resistive load, 0.8 for inductive load.

1.5 square wire load

The square number of electric wire is an oral expression in decorating water and electricity construction, often say a few square electric wire is to do not add a unit, square millimeter namely. Generally speaking, the empirical load is about one kilowatt per square wire when the grid voltage is 220V. Copper wires can carry 1-1.5 kilowatts per square meter, and aluminum wires can carry 0.6-1 kilowatt per square meter. So an electrical appliance with a power of one kilowatt needs only one square square of copper wire. When it comes to current, copper wires can carry currents from 3A to 5A per square meter at short distances. Heat dissipation conditions good take 5A/ square mm, bad take 3A/ square mm 1.5 square wire load is 1.5 kilowatts or so.
