Double site break isolator switch 3DN2

high-voltage2-pole

Double side break disconnectors are primarily used in substations with limited phase space and where a vertical opening of the current path is not possible. The current path makes a horizontal rotating movement. •Has three supporting insulators •The center insulator can rotate and carries the current path •Outer supporting insulators carry the fixed contacts •Two open separation sections •Compact and stable design allows for high mechanical tensile loads •Combination with surge arresters possible •Available with self-interlocking mechanism and in various colors •Sophisticated contact system ensures long service life and requires no maintenance effort •Extended RIV limits for each voltage level reduce magnetic interference for increased efficiency and reliability •Tested according to national and international standards, such as IEC, ANSI, GOST R and GB Our disconnector and earthing switch technology The technology of our products sets international trends. We continuously ensure our high quality through optimized production processes, constant product development and a certified quality management system. •Short circuit conditions increase the contact force •Highest dynamic/thermal stability in the event of leakage current •Optimized for applications with silver plating •Lubrication free solution •Maintenance-free (long term) •Many years of operating experience (+ 40 years) •Our contact system concept is largely based on the original RUHRTAL design
