LWB-72.5/123/145 Outdoor SF6 Breaker | product structure LWD-72.5/123/145 SF6 breaker air passage connection and density relay cable diagram(Diagram .1) LWD-72.5/123/145 SF6 breaker body adopts self-energy arc extinction principle and spring operating mechanism. Every breaker is composed of three monopoles installe! on a bunton and a spring operating mechanism. Among three monopoles is Connecting System. The phase to phase driving type is double pull bar structure. It reduces impact on the explosion chamber. The spring operating mechanism is installe! on the middle of bunton bottom(Diagram 2). LWD-72.5/123/145 SF6 breaker adopts double 0 seal, reducing SF6 leakage. In order to watch SF6 easily, a pointer density relay is used. The arrangement of incoming and outgoing line is very flexible adopting "I" form.
