Double End-Break Switch
Type: D
Insulator Profile: Parallel or Vee Configuration
Orientation: Horizontal Upright, Vertical, Underhung
Voltage: 34.5 – 230 KV
Current: 600, 1200, and 2000 Ampere
Description
A three insulator, group operated, side-opening, air-break disconnect switch, with a single center rotating insulator per phase for operation.
Application
Comparable to a vertical break and often used as a substitute where there are overhead clearance problems. Has the same phase spacing requirements as a vertical break.
Frequently used for line disconnecting, isolating and by-passing breakers and transformers, bus sectionalizing, and isolating arrestors, metering equipment, and other apparatus. Can be either pole or substation structure mounted.
Features & Benefits
- Minimal phase spacing reduces structure size and weight
- Excellent ice breaking characteristics
- Horizontal break minimizes overhead clearance issues
- Horizontal break aligns with substation bus in low profile substations to maintain desired appearance
- Lower cost compared to vertical breaks
