產品概述：

Product Overview：

KYN28-12內金屬鎧裝移開式開關設備是三相交流50(60)Hz額定工作電壓12千伏、額定工作電流1250A的戶內成套配電裝置。其母線系統為單母線宜可派生出單母線帶旁路和雙母線結構。具有實現"五防"閉鎖功能。該柜體既能配用ZN63 (VSI)真空斷路器，也可配用ABB公司的VD4真空斷路器，實為一種性能優良的配電裝置。

KYN28-12 indoor metal armored withdrawable switchgear is the indoor distribution equipment assembly, of which the three-phase AC 50(60) Hz rated working voltage is 12kV and the rated working current is 1250A. Its busbar system adopts single busbar; however, the structure of single busbar with bypass and the structure of dual busbar can also be derived. The switchgear has the "five protection" interlocking function. Since it can be used in combination with ZN63 (VSI) vacuum circuit breaker or VD4 vacuum circuit breaker from ABB Group, it is the power distribution equipment with excellent performance.
