DOV Surge Arrester is a miniature version of Distribution Heavy Duty Surge Arrester yet meeting all technical characteristics. The design of DOV surge arrester includes a compact metal oxide varistor, size of which is 60% less than the standard size used in other surge arresters.  The reduced size of the metal oxide varistor helps in saving energy and resources at multiple levels.  

Less volume of metal oxides for producing varistor 
Increase in production processes, faster manufacturing 
Reduction in logistics costs 
Ease of installation, etc. 
Reduces carbon footprints 

Since the installed surge arrester is in use for the lifetime of an electrical power system, low power losses give added advantage to Utilities.  The DOV surge arrester with silicone housing provides excellent surge protection against over-voltages and improved insulation in a contaminant environment.

Short circuit performance of a surge arrester is a vital function, and in case of failure which is a remote likelihood, equipment is protected without causing major damages as the DOV is built on a cage design offering excellent fail-safe short circuit performance.  

DOV surge arrester is one of Raychem RPG’s design innovation offering exceptional medium voltage surge protection for Utilities.
