Product overview
SW2-66 (SW2-72.5 abroad) oil-less circuit breaker is an outdoor three-phase AC 50Hz high-voltage power equipment. It is mainly used for the control and protection of transmission and distribution lines. The different operating mechanisms for connection can be divided into SW2 -60Ⅰ, SW263Ⅱ, SW2-66Ⅲ and other types, in order to reduce the floor space, the mechanism can also be placed on the side of the circuit breaker to form a side-mounted mechanism. For those with special requirements that meet no-load long lines, there is also the SW2-66ⅢL type. In addition, in addition to the ordinary type, the product also has an anti-fouling type.
Both types SW2-66Ⅰ and Ⅱ are equipped with a CY5 hydraulic mechanism, which can perform slow action, fast action, and one-time automatic reclosing.
SW2-66Ⅱ oil-less circuit breaker is equipped with a CD5-370X electromagnetic mechanism or a CQ-300A pneumatic mechanism. It can use a hydraulic jack for manual slow action, electric quick action and one-time automatic reclosing. And has the performance of free tripping.
In addition to meeting the product technical conditions, the SW2-66 oil-less circuit breaker and operating mechanism also meet the requirements of GB1984-89 "AC High Voltage Circuit Breaker" which is equivalent to the IEC standard.
