A cross arm is provided, for use in a support structure for conductors within an electrical grid. The cross arm is made of weather resistant glass fibre reinforced two component polyurethane based polymers and has a“C”cross sectional shape typically arranged in a double configuration. Pairs of the cross arms are attached to utility poles in a parallel position on opposite sides of the utility pole to meet predefined design conditions. Alternatively, a single cross arm may be attached to a utility pole. |
