Introduction<\/h3>\n

Valve arrester RVO-10 U1 for protection of overhead power transmission lines and equipment of transformer substations from short-term overvoltages of switching or inductive-lightning character.\u00a0<\/span>Equipment of this type finds application in electricity transmission and distribution networks in industrial and municipal facilities.\u00a0<\/span><\/p>\n

 <\/p>\n

Design features RVO-10U1<\/span><\/h3>\n

The main elements are non-linear resistors connected in series with spark gaps.\u00a0They are reliably protected from the negative effects of the environment by a sealed porcelain case, which provides the necessary stability of the product characteristics.\u00a0<\/span><\/p>\n\n\n\n
