Composite polymer insulators are an attractive alternative to traditional ceramic or glass insulators for overhead power distribution to towns and cities across the globe. In countries like Canada, there are two specific challenges to the long-term use of these materials: chemical stress in the form of salts that are used on roads in winter conditions, and large seasonal temperature fluctuations. Both of these environmental factors can impact the water repellency of the silicone materials. Our lab has developed a combination of experimental techniques for the application of salt stress and realistic (40 kV) high voltage to simulate electrical power line conditions. This proposal investigates the effect of temperature cycling, salt and high voltage exposure to the surfaces of insulators. The knowhow resulting from these projects furthers Canadian innovation in a global power delivery market, and provides unique training opportunities for the next generation of materials scientists and engineers.

复合聚合物绝缘子是传统陶瓷或玻璃绝缘子的有吸引力的替代品，用于全球城镇的架空配电。在加拿大等国家，长期使用这些材料面临两个具体的挑战：冬季道路上使用的盐形式的化学应力，以及季节性温度波动大。这两种环境因素都会影响有机硅材料的拒水性。我们的实验室开发了一种结合盐应力和实际（40千伏）高压的实验技术来模拟电力线条件。本文研究了温度循环、盐和高压对绝缘子表面的影响。这些项目产生的专业知识进一步推动了加拿大在全球电力输送市场的创新，并为下一代材料科学家和工程师提供了独特的培训机会。
