The strain clamp includes a steel anchor, a clamp main body which is manufactured from heat-resistant aluminium alloy and a wire-guiding plate. One end of the steel anchor is a hanging ring, the middle part of the steel anchor is a pressing-connection body and the other end of the steel anchor is a wire-clamping tube which is manufactured from heat-resistant aluminium alloy. Both of the wire-clamping tube and the clamp main body are in the shapes of hollow tubes. The pressing-connection body and the wire-clamping tube are together inserted into the clamp main body. The clamp main body and the pressing-connection body are fixedly combined with each other in a clamping manner. The wire-guiding plate is sleeved by the clamp main body and is fixed to the clamp main body. Compression ratios of both of the clamp main body and the wire-clamping tube are 13%. An inner diameter of the clamp main body is 3.4 times as the inner diameter of the wire-clamping tube. By means of the strain clamp, pressing-connection strength between the strain clamp and the aluminium-clad aluminium conductor steel reinforced cable can be ensured when a temperature is increased.
