Application:
Recloser or regulator bypassing to reduce the impact of equipment maintenance on network reliability.
Features include:
- Robust square-tubular copper blades.
Options:
- Porcelain or polymer insulators
- Stop-position angle
- Left- or right-hand bypass operation
- Custom terminal arrangements
- Loadbreak hooks.
Bypass recloser assembly type B-2
Siemens type B-2 bypass assembly offers quick and simple installation. Originating from the reliable B-2 single-phase switch, all three-phase units ship preassembled on the crossarm for easy installation at the site, which reduces time and overall installation costs. A B-2 bypass assembly is customizable with porcelain or polymer insulators and galavanized or fiberglass bases. The assembly provides a means for bypassing and disconnecting pole-mounted reclosers. Proper sequence operation allows the recloser to be bypassed and isolated from the system.
Goals:
- Reduce downtime when maintenance is required
- Minimize installation time through pre-assembly.
