THE DESIGN AND CONFIGURATION OF METALOXIDE SURGE ARRESTERS
Metal oxide surge arresters are used in where must be protected against over- voltage power transmission
lines, electrical appliance, hosting facilities, distribution transformers and facilities with medium voltage cables.
The metaoxide (Zn0) varistors are formed of the entirely metallized electrodes with perfect structure in variable resistance
(non-linear) and produced under the current IEC standards (class 1).
All are being tested and joins production phase with care.
The varistor blocks are typically seperated into two; 5Ka and 10 kA.
