The utility model relates to a steel cord single-wire tension equalizer and an electric conduction clamp wrapping and connecting rod samples. The equalizer consists of a collection wire nozzle, a noseplate, a wire transmission wheel arranged on a wire transmission roller frame and a tension balance wheel; wherein the wire transmission wheel, a tension wheel, a driving pulling wheel, an engaged pulling wheel and a motor frame of a micro driving motor are provided between the noseplate and the wire transmission wheel. two groups of tension balancers consisting of the tension wheels, the driving pulling wheels and the engaged pulling wheels are additionally arranged between the wire part of a strander and the noseplate and pull steel wires of a multi-layer strander cord thread with the layering method. The single wire of a steel cord thread is pulled to the wire transmission wheel through the tension wheel, which guarantees the tension force of the single wire to be even and identical before the steel cord thread is twisted and avoids the shortcomings such as the foaming, wire skipping and uneven twisting because of uneven tension force. The steel cord thread has the advantage of sound twisting quality. After the tension equalizer is additionally arranged, the tension force of the wire releasing of the single wire of the cord thread is only one fifth of the tension force before the tension equalizer is not additionally arranged; therefore, the tractive force of the strander is lowered. The abrasion of an equipment, caused by too big tractive force, is reduced. The equipment has the advantage of long service life.
