12-27kV OVP Pole of Post-Mounted Vacuum Circuit Breaker

Product Introduction
The product adopts an embedded pole structural form that integrates voltage and current sensors by outdoor epoxy resin APG process, and can simultaneously monitor the voltage signals at both ends of the vacuum envelope, simultaneously collect two groups of current signals (single-phase pole), and output fully shielded signals to the control terminal, making it easy for the mechanism to achieve higher protection level, small size and light weight.
