The Main Features Of Embedded Pole
◆High Reliability And Stability
Compared with assembly pole, embedded pole use much less spare parts, conductor faying surfaces and jointing fastening piece, so that simplify the conductance circuit’s assembly links, lower the circuit’s resistance and improve galvanic circle’s reliability and stability.
◆Stable Insulating Ability
Vacuum interrupter embedded with epoxide resin solid material, guarantee the minimized affection from external environment, and its external insulating ability will avoid the influence from dust, moisture, small animal, condensation and filthy, fully satisfy requirements of GB/DL standards of secondary filthy area.
It will give more sufficient protection for vacuum interrupter., free of mechanical collision in process of assembly and transportation.
Its insulating media is epoxide resin, pole to pole distance will shorten, using less vacuum circuit breaker’s space.
Because the whole pole embedded to overall part, vacuum interrupter gets fully protection, vacuum interrpter’s free maintenance also benefit the circuit breaker’s free maintenance.
◆More Environment Protection
To some degree, embedded pole circuit breaker will take over SF6, so it is more environment friendly.
