Each set consists of two ties, which is usually illustrated. #7 @ 12" EW, EF Number 7 rebar spaced 12 inches apart, placed in each direction (each way) and on each face.
The skin effect and proximity effect cause conductors to exhibit higher resistance to alternating current (AC) than to direct current (DC). Due to the dual inverse nature of the electromagnetic field, the skin effect dominates at frequencies less than about 2 MHz; at higher frequencies, the proximity effect becomes the dominant force, and Litz wire induces more DC losses than solid wire or ...
