Circuit Switchers – Vertical (CSV, CSV-CB-DB)
Southern States disconnect switches can be integrated with the CSV on a common structure or platform. Most common designs include an integral double sidebreak “Vee” switch (model CSV-DB) or an integral center break “Vee” switch (model CSV-CB). These switches can be specified by the customer to be either manually operated or motor operated.
- Compared to dead tank circuit breakers, circuit switchers have a significantly smaller footprint and utilize significantly less SF6
- Simple, easy erection minimizes field installation time required.
- Structure baseplate can have its hole locations and hole sizes varied when required to fit existing foundation locations and anchor bolt sizes.
- Gas density switch with low pressure alarm and low pressure lockout contacts allow remote gas monitoring.
- Local visual indication of gas system by an SF6 pressure gauge.
- Ships with minimal gas pressure for safety during transportation and in handling during installation.
- Adaptable to a wide variety of installation height requirements and foundation requirements.
- 4 hole NEMA terminal pads are readily reversible to fit specific installation requirements.
- Each unit is completely assembled and tested at the factory with only the disassembly required to meet shipment restrictions being performed
