RVD-145 Dead tank vacuum circuit breaker

This PDF product catalogue supports tender comparison, high‑voltage transmission‑substation project selection and pre‑sales technical evaluation. This dead‑tank vacuum circuit‑breaker complies with IEC 62271‑1, IEC 62271‑100 and relevant ANSI/IEEE standards.

It adopts vacuum interrupter with zero‑F‑gas clean‑air insulating medium of zero GWP, achieving type‑tested gas‑compartment annual leakage rate below 0.1 %, rated absolute filling pressure 0.8 MPa. This catalogue records full dielectric‑withstand values, peak & 3‑second short‑time withstand‑current grades, multiple reclosing operating‑sequences, wide ambient‑temperature range of ‑50 ℃ ~ +55 ℃, >25‑year first major‑inspection interval and >50‑year expected service‑life.

Modular structure with compact bay dimension, optional integrated LPIT low‑power instrument transformer, spring‑stored‑energy actuator, supports both indoor and outdoor deployment. Custom‑manufacturing covering design adjustment, assembly and project‑specific factory‑acceptance‑test is available for high‑voltage grid projects.
