Self-Healing Silicones for Outdoor High Voltage Insulation: Mechanism, Applications and Measurements

This paper discusses the state of art in application self-healing silicone-based materials for outdoor high-voltage insulation. Both dynamic behavior dimethyl side groups silicone rubber and diffusion a bulk siloxane to maintain low surface energy are respectively reported as intrinsic mechanisms responsible rubber. Localization, temporality, mobility, type synthesis aspects defining efficiency ability In addition, deterioration with filler loaded into insulation housing composites is discussed. Taking property consideration among other properties insulators, such tracking erosion resistance, can be useful design practice at material development stage. Hydrophobicity retention, recovery, transfer measurements discussed indicators Nevertheless, there remains need standardize them tests The intended shed light on hydrophobicity key parameter insulating composites, similar resistance.
