Our Suspension Insulators combine the high tensile strength of Fiber Reinforced Plastic (FRP) with high voltage shed profile, to produce a rugged, lightweight suspension insulator for overhead line applications.
The glass fiber core provides high mechanical strength with tensile values of greater than 70 kN/15,000 lbs. Our silicone insulator profile is backed by 40 years of our Raychem, Bowthorpe EMP and Axicom medium and high voltage product design. Silicone is a hydrophobic material with a performance of tracking/erosion resistance with UV stability. It also gives a good balance of technical performance in a wide range of climatic and pollution conditions.
The construction consists of a compact creepage design insulator profile which has the same shed diameter in order to maximize flashover performance over a minimum insulator length. There is also a secondary moisture barrier placed around the interfacial seal.
