ABSTRACT OF THE DISCLOSURE In order to overcome the disadvantages that wooden cross-arms for supporting electrical insulators for power transmission lines are subject to deterioration and to internal defects in the wood there is provided a utility insulated cross-arm for supporting electrical wires from a utility pole comprising a rigid bar made of insulative material, having left and right ends and a central portion. Two diagonal members integral with the bar, are located on either side of the central portion of the bar, the diagonal members being joined at a peak, forming a triangle with said bar. A plurality of support members are mounted one at the peak, and others distributed along the bar, each having a support surface with a trough, for supporting the electrical wires, the support members also having lateral depressions. Attachment means is provided for securing the electrical wires to the support members by rigidly fastening the attachment means to the electrical wire and the lateral depressions of the support members. A concave surface is located at the peak of the diagonal members, and at the central portion of the bar, the concave surface running perpendicular to the bar, and the concave surface having apertures therein for mounting the cross-arm to the utility pole.
