16.5kV–27 kV Medium Voltage Metal-Clad Switchgear 16.5kV–27 kV na Medium Voltage Metal-Clad Switchgear

Paliwanag

Ang kalidad ng Square D Masterclad™ Medium Voltage Metal-Clad Switchgear ay nagmumula sa disenyo at proseso ng paggawa na nakatuon sa mahabang terminong performance ng switchgear na may pinakamataas na antas ng reliabilidad. Ang maasintas na performance at seguridad ay naging mas mabuti dahil sa matibay na konstruksyon ng Masterclad switchgear. Ang switchgear ay binubuo ng mga indibidwal na grounded, compartmentalized na steel structures upang protektahan ang mga operating personnel at equipment.

Ang mga komponente ng Masterclad switchgear ay kasama ang available state-of-the-art electronics tulad ng ION power quality monitoring at EASERGY protective relays, EcoStruxure™, integrated racking, at automatic throwover systems.

Ang standardization ng disenyo ay kumakatawan sa serye ng basic modular units, control packages, at instrumentation. Para sa karamihan sa mga switchgear ratings, circuit configurations, at functions, ginagamit ang isang basic size unit. Ang mga tampok na ito ay nagbibigay ng application flexibility, versatility, at efficiency, na nagbabawas ng lead time at engineering time na inilalaan para sa planning at layout ng switchgear.
