SDI 90.150 and SDI 90.280 Composite Insulators

Product catalog summary

Introduction
SDI 90 composite insulators are the latest advancement in Ensto's composite insulator series, designed for utility networks. These insulators are lighter yet maintain strength and durability, meeting IEC 61109 standards.

Specifications
