The utility model provides an aluminum alloy core aluminum wire lead large steel anchor type tension wire clamp. The tension wire clamp is disposed at the terminal of an overhead transmission line for anchoring an aluminum alloy core aluminum wire lead and maintaining electrical and mechanical performance of the aluminum alloy core aluminum wire lead. The tension wire clamp comprises a large steel anchor and an aluminum pipe which are arranged along the same axial direction. The aluminum alloy core aluminum wire is arranged in the aluminum pipe. The improvements are as follows: one end of the large steel anchor is provided with an oval ring , the other end of the large steel anchor is provided with a hole along the axial direction of the large steel anchor, and the outer side in the middle of the large steel anchor is provided with a thread; the aluminum alloy core of the aluminum alloy core aluminum wire is arranged in the hole; and an aluminum sleeve is arranged between the aluminum alloy core aluminum wire and the aluminum pipe. Compared to the prior art, the aluminum alloy core aluminum wire lead large steel anchor type tension wire clamp has the following advantages: the aluminum alloy core of the lead is arranged inside the large steel anchor and is crimped in a fluid pressure mode so that the effectiveness and stability of holding the lead by the large steel anchor are greatly improved; and the fluid pressure mode is adopted, the technology is mature, the crimping quality is easily ensured, and the crimping problem of the aluminum alloy core aluminum wire is overcome.
