Performance of Polymeric Insulators under Artificial contamination Conditions as IEC – 587

Abstract

Many companies have started manufacturing insulators from organic polymeric or silicone materials as an alternative to glass or porcelain

insulators used in high and medium voltage networks، and these insulators are called non-ceramic insulators, which have the Lightness and flexibility, Ease of transportation and installation, Unbreakable, &  Hydrophobicity property, which helps to improve the performance of these insulators in pollution conditions.

The use of these insulators in a network imposes that the properties, advantages and performance of these insulators in the long term and in all circumstances، including the various environmental pollution conditions, be constant and good, otherwise the failure of these insulators after installing them in the network will cause significant material and technical losses on the development process and the national economy, so this research was conducted to clarify the dimensions of this problem and to be an assistant in making some clarifications about the obsolescence of these insulators in pollution conditions This is according to IEC – 587.
