Ang A2Z-BBMC Series Back-to-Back Double Busbar Metal Clad Modular Switchgear ay isang espesyal na medium voltage switchgear na solusyon na idinisenyo sa pamamagitan ng pagsasama ng dalawang magkahiwalay na switching module sa isang back-to-back na configuration sa loob ng parehong enclosure.
Ang disenyong ito ay nagbibigay ng maximum power density sa limitadong espasyo habang nag-aalok ng mataas na operational flexibility sa pamamagitan ng double busbar structure at access mula sa magkabilang panig. Ang serye ay angkop para sa mga aplikasyon kung saan kinakailangan ang service continuity, ligtas na operasyon, compact na disenyo, at maaasahang switching performance.
Ang A2Z-BBMC Series ay ginawa sa tatlong pangunahing configuration ayon sa mga kinakailangan ng proyekto: fixed circuit breaker type, withdrawable circuit breaker type, at withdrawable circuit breaker na may withdrawable voltage transformer type.
Ang serye ay idinisenyo alinsunod sa IEC 62271-200 at mga kaugnay na pamantayan ng IEC. Ang modular structure nito, internal arc safety, mechanical at electrical interlocking system, at front at rear access capability ay nagbibigay ng maaasahan at mahusay na solusyon para sa mga transformer substation, medium voltage distribution system, at industrial applications.
