The invention discloses an excitation characteristic test coiling frock for a coil of a current mutual inductor. The coiling frock comprises two insulating boards and a plurality of conducting wires, both ends of which are fixed onto the two insulating boards. A locking device is arranged on the two insulating boards. After the two insulating boards are fastened, a plurality of conducting wires are connected end to end in sequence to form a loop. The interval and the length of the conducting wires are fixed, so the coil is coiled up by fastening the two insulating boards only. The test coiling frock has the advantages of even coiling, high working efficiency, small coiling radian and long service life. In addition, materials and labor are saved.
