Application of 25 square auto cable
China [CN] Charging piles are a very common energy supplement nowadays, but there are still a lot of people who don't know how many square feet of cable are needed to install a charging pile. The wire harness thickness of the charging pile is not uniform, but mainly depends on the storage capacity of the charging pile and the voltage the harness is subjected to when circulating electricity, in general the wire of the charging pile is much thicker than other wires.
Charging piles have single-phase and three-phase, whether dual-phase or single-phase, first of all to convert to AC incoming current how big.
For single-phase charging piles (AC charging piles) I=P/U;
For a three-phase charging post (DC charging post) I=P/(U*1.732).
From this it follows that the cable is selected according to the current magnitude. (Cable selection can be done by referring to relevant manuals or regulations).
Single-phase charging pile is generally 7KW (AC charging pile) I=P/U=7000/220=32A Copper core cable of 4 square mm should be used;
Three-phase charging post (DC post) 15KW Current 23A Cable 4 square mm;
30KW current 46A cable 10 square mm; 60KW current 92A cable 25 square mm;
90KW current 120A cable 35 mm2;
