High Voltage Equipment
Why use HAPAM disconnectors?
- More than 75 years of experience
- Durable and reliable design
- More than 30,000 disconnectors and earthing blades currently in service in more than 80 countries around the world.
- Virtually maintenance-free.
Main blade
The main blade is made of an aluminum tube with silver-plated copper contacts at both ends. During the closing of the disconnector, the main blade performs a double movement: first, the main blade descends until it reaches a completely horizontal position and then rotates so that contact pressure is applied at both ends of the disconnector.
The main contacts are of "inverted loop" design, which makes them suitable for very high short-circuit currents. anti-corona screens are provided.
Grounding blades
Hapam disconnectors can be equipped with grounding blades, installed on the right and/or left side.
The grounding blade consists of an aluminum tube, provided with silver plated contacts at both ends.
The grounding blade consists of an aluminum tube, provided with silver plated contacts at both ends.
Types of disconnectors:
- Central-Break Disconnectors SSBII
- Double break disconnectors SSBIII
- Vertical Opening Disconnectors VSSBIII
- Semipantograph Disconnectors VKSBIII
- GSSB Pantograph Disconnectors
- Earthing blades Type TEB
Ceramic Insulators
- Seves and its substation insulator business were established in 2007 with the acquisition and integration of PPC Insulators and Santana Insulators into the Seves Group. With more than 100 years of experience in its current Substation Division, Seves is the world’s leading supplier of high-voltage insulators. As a result, the group is well-positioned to serve customers worldwide with the broadest product portfolio.
