10kV Porcelain Surge Arresteer

Additional information

Product Details:

Porcelain Surge Arrester RVO-10 (РАЗРЯДНИК РВО-10 У1)



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. Equipment of this type finds application in electricity transmission and distribution networks in industrial and municipal facilities. 


Design features RVO-10U1

The main elements are non-linear resistors connected in series with spark gaps. They are reliably protected from the negative effects of the environment by a sealed porcelain case, which provides the necessary stability of the product characteristics. 

1. Spark gaps

2. Nonlinear resistors

3. Sealed porcelain body
