Development of Polymer Crossarms

This paper reports the developing and manufacturing process of polymeric crossarms in place of conventional crossarms made of steel used for overhead lines. The use of insulated crossarms has been mandatory in order to achieve the required line compaction in the pole. The developed polymer crossarm is characterised by significantly less weight, easier handling, much longer insulation length which leading to reduce the flashover outage from bird nest.
