Wear Characteristics of Aluminum Cable Steel Reinforced (ACSR) under Dry and Acidic Conditions

On a self-manufactured overhead line Aeolian Vibration simulation tester, micro-vibration wear characteristics of aluminum cable steel reinforced (ACSR) under dry and acidic conditions were investigated. The surface topography of contact area between inner and outer layer stranded wire was analyzed by using scanning electronic microscopy. Morphology and size of wear particle were analyzed by ferrographic microscope. The results show that in both experiment conditions, wear mechanism of stranded wire near the cable clamp mainly included adhesive wear and fatigue wear, while near the middle section mainly there were adhesive wear and grain-abrasion. In acidic experiment conditions, the main wear mechanism was corrosive wear in stranded wire.
