Abstract
This paper deals with the flashover voltages on samples of silicone rubber/ethylene propylene diene monomer (SiR/EPDM) mixtures under the influence of a uniform electric field. Five different mixtures of SiR/EPDM were investigated. Various SiR/EPDM mixtures (100% EPDM, 10% SiR + 90% EPDM, 30% SiR + 70% EPDM, 50% SiR + 50% EPDM, 70% SiR + 30% EPDM, 90% SiR + 10% EPDM, 100% SiR) were tested for different water droplet arrangements, different water conductivities, different droplet volumes as well as different droplet positioning w.r.t. the electrodes. The 50% SiR + 50% EPDM mixture proved to be the best mixture regarding the flashover voltage.
Highlights
Polymeric outdoor insulators are in use in the past few decades [1]
Sykaras et al.: A Study of SiR/ethylene propylene diene monomer (EPDM) Mixtures for Outdoor Insulators less expensive compared to silicone rubber
It seems that mixture C (50% SiR - 50% EPDM) presents a satisfying flashover behavior
