Background

The Provincial Electricity Authority (PEA) has supplied electrical power in various forms. A cable spacer is one of the most important devices used with space aerial cable (SAC) for carrying the cable weight and safely putting it in order. The high density polyethylene (HDPE) cable spacer currently in used by the PEA is prone to shattered, degraded, electrical-tracked and even ignited. These negative aspects affect the service quality of PEA and the confidence in HDPE cable spacer performance, resulting in a significant amount of HDPE spacer discarded in storage facility.  Therefore, the HDPE cable spacer with improved quality would contribute to a longer service time and a reduction of the operating cost of the PEA.
