Porcelain disc suspension insulator design:
Designed and manufactured to give unparalleled performance and reliability in the field, millions of our porcelain disc suspension insulators continue to perform successfully around the world. In particular, porcelain disc suspension insulators are most often specified for EHV, UHV and HVDC transmission lines with both high reliability through accumulated technology and excellent long-term performance. Available for any voltage and contamination level by careful selection and design, porcelain disc suspension insulator maintain both their electrical and mechanical strength over a long period of time without deterioration. Porcelain disc suspension insulators are also available with semiconducting glaze for even better contamination performance.
