The utility module relates to an integrated structure of a sub-conductor spacer and a support, wherein the sub-conductor spacer comprises a regular polygon shaped body and wire clamps arranged at corner parts of the regular polygon shaped body; the support is an integral frame and fixedly connected with the sub-conductor spacer into an integrated body; the support comprises a first support arm, a second support arm and a connecting beam, the first support arm and the second support arm are fixedly connected to the regular polygon shaped body, and the connecting beam is connected between the first support arm and the second support arm; two ends of the connecting beam are symmetrically provided with a first connecting part and a second connecting part which are connected with an alternate spacer respectively; and the included angle of connecting lines between the two connecting parts and the center of the regular polygon shaped body is 60 degrees. The integrated structure of the sub-conductor spacer and the support solves the problem existing in the prior art that the support and the sub-conductor spacer are damaged, broken down and difficult to install on site; and the sub-conductor spacer and the support are enabled to be stressed more uniformly, the service life is prolonged, and the sub-conductor space and the support are installed more conveniently.
