145kV(123kV)Dead tank vacuum circuit breaker drawing

This drawing mainly provides overall outline, phase arrangement, terminal connection dimension, anchor bolt installation interface and foundation layout. Complete electrical parameters shall refer to official product datasheet, not only this mechanical drawing.

It uses clean air (80%N₂+20%O₂) as insulation medium, zero SF₆ and fluorinated gas, GWP=0, non‑toxic, no toxic decomposition by‑products, no special gas disposal required at end‑of‑life.

It complies with IEC / IEEE standards. Custom‑manufacturing is available; we can provide full‑set solutions covering design, assembly and test based on project requirements.
