The invention discloses a suspended ground pole and an application method thereof, and relates to the field of electric machinery. The ground pole comprises a conductive metal pole, wherein an insulating layer wraps the peripheral surface of the conductive metal pole; a plurality of annular grooves (3) are formed in the axial surface of the insulating layer at equal intervals; the depths of the annular grooves (3) are smaller than the thickness of the insulating layer; one segment of conductive metal pole free of the annular insulating layer is arranged on the peripheral surface of the insulating layer between two adjacent annular grooves (3); a stepped cylinder device is clamped between two adjacent annular grooves (3) in a sleeving manner; each stepped cylinder device comprises two pairs of stepped cylinders in one-to-one correspondence; and each two pairs of stepped cylinders sleeve the outer surface of the insulating layer between two adjacent annular grooves (3). The suspended ground pole can ensure sufficient and effective contact area of a wire drained to the ground and the ground pole, prevents the wire drained to the ground from sliding off, and simultaneously solves the problem of an electric wire suspension position set by a worker in a working area.
