Depending on the required level of protection, temporary retension and ability to energy absorption varistors gather in several consistently connected columns. ABB possesses all necessary equipment and experience for production of such varistors.
Impulses of retension possess the high-frequency component leading to increase of load of blocks and a cover that has to be considered when developing such varistors. Varistors can have porcelain or polymeric external isolation. The first option has advantage at assembly of several columns in one case. The second has advantage in flexibility and ease of installation at assembly in the form of racks. This advantage is of great importance in cases when the expensive EHV isolated platform is designed with use of these varistors.
The racks of MXE collected at ABB plants facilitate an installation field assembly.
ABB has a possibility of delivery of varistors with energy of a single impulse to 140 MDzh.
