The invention provides an ice damage prevention strain clamp which comprises an aluminium tube, a steel anchor and a sealing bolt, wherein the steel anchor is formed by sequentially connecting a lead press connection part, an aluminium tube press connection part and a pull ring; the lead press connection part and the aluminium tube press connection part extend into the aluminium tube; the aluminium tube press connection part is in press connection with the aluminium tube; a grease injection hole is formed in the outer wall of the aluminium tube and is just opposite to the lead press connection part or the aluminium tube press connection part; the sealing bolt is connected with the grease injection hole. The grease injection hole is formed in the aluminium tube, conductive grease can be injected into a cavity in the aluminium tube, and the aluminium bolt is used for sealing after grease injection, so that when the strain clamp is hung in an inverted way, rain water can not be stored in the strain clamp since the cavity of the strain clamp is fully filled with the conductive grease, and the aluminium tube of the strain clamp is prevented from being damaged by the expansion of frozen water in the operation project of the strain clamp.
