Our medium voltage arresters are used to protect medium voltage networks and equipment from overvoltages caused by lightning and switching surges. The selection of arresters depends on the neutral point treatment of the networks.
Depending on your requirement, our surge arresters can be used for indoor or outdoor application.
SBKW stands for Innovative design with an active part in fiber optic cage.
Direct silicone injection prevents the formation of air bubbles, which can lead to internal partial discharge in the arrester.
Due to the versatile configuration options, there are almost no limits to the adaptation to their needs.
