2.5 square copper electric wire power:the load level of the wire is mainly dependent on the current,also depends on the voltage level. Some people say that 2.5 square electric wire load is 2 kilowatts, some people say that the correct is 2.5 square electric wire load 1.5 kilowatts. Parlance is different, the parameters are different.
Under normal circumstances below 50A 1 mm2 safe carrying capacity is 6A, 50 ~ 100A current 1 mm2 of the safe carrying capacity is 5A, more than 100A current the general take 1 mm2 of the safe current is 2.5A,so know how much the square of the copper cable will be able to calculate the current.
According to the three-phase alternating current formula:P=1.732*U*I*cosφ，cosφ is the power factor,choose 0.8;This is three-phase power calculation formula. Single phase:P=U*I*cosφ,cosφ is the power factor power factor, the resistive load is 1, the inductive load selected 0.8.
BV wire and BVR multi-strand soft copper wire is different, of course and rubber cable YC load is different, rubber cable cable load than BV / BVR / RVV like plastic wire is better. The outer insulation will affect the wire on the number of load. General 2.5 square wire load is 2 kilowatts, while the rubber cable full load can reach 3 kilowatts.
