Detailed Description

4mm2 copper core cable for 100m of 7kw charging pile


Charging pile is a very common energy supply equipment, but there are still many people who do not know how many square wires are needed to install charging pile. After all, the wire harness thickness of the charging post cannot be unified. It is mainly determined by the power storage capacity of the charging post and the voltage borne by the wire harness when the power is circulated. How big is the cable for the 7kw charging pile?


There are single-phase and three-phase charging piles. However, whether single-phase or two-phase, the current of AC incoming line shall be converted first.


For single-phase charging pile (AC charging pile) l=P/U


For three-phase charging pile (DC charging pile), l=P/(U * 1.732)


After calculating the current according to this algorithm, select the cable according to the current size.


Charging pile cable related manuals/procedures:


The single-phase charging pile is generally 7KW (AC pile), l=P/U=7000/220=32A, and 4mm2 copper core cable shall be used.


Three phase charging pile (DC pile):


15KW current 23A cable 4mm2 ;

30KW current 46A cable 10mm2 ;

60KW current 92A cable 25mm2 ;

90KW current 120A cable 35mm2 ;


All charging posts shall have zero line and ground wire; Therefore, the single-phase cable shall have three cores, and the three-phase cable shall have five cores.
