SG Mile 15 airinsuleted switch gear

Product number:
Based on vacuum switching technology, air insulation, digital protection and arc-flash relays, air-insulated switchgear inherently saves the environment as it is an SF6-free switchgear.

Exceptional safety In addition to IEC 62271-200 requirements, the application of TAVRIDA ELECTRIC VCB with MAGNETIC ACTUATORS in MILE provides unique and unrivalled safety features such as remote and safe manual closing of VCB with a palm-held manual generator and the fastest arc fault interruption in less than one cycle. High operational reliability The robust enclosure, made of 2mm corrosive resistant hot-dip galvanized metal sheets with reinforced doors and a safety labyrinth allows fast and simple erection even on an uneven floor. A rivet nut design provides not only the rigidness of construction but also an opportunity to replace metal parts on site without the use of special tools. An emergency trip push-button is located in the center of the panel. It has a striking, protruding design protected against accidental operation. The trip button can be quickly spotted in an emergency. Large and clearly visible mechanical position indicators located in view of an operator allows him to positively identify the operating status of the draw-out unit, VCB and earthing switch. Each mechanical indicator abruptly changes its status so that it exactly corresponds to the status of the switching device. Mechanical position indicators are duplicated by electrical auxiliary contacts to provide electrical signals into secondary circuits. Lockable access to the VCB racking in/out mechanism by a metallic shutter prevents unauthorized operations and interlocks the VCB in the trip position prior to racking a draw-out unit. An LV plug interlock visually prompts an operator to connect the draw-out unit to secondary circuits before the compartment door is closed. Refined accessories, such as door hinges, handlebars, locks and electrical indicators and buttons withstand thousands of operations and guarantee the appearance of a beautifully crafted product. Minimum service checks on site. MILE is designed for a service life of at least 30 years. The VCB, earthing switch and cast resin insulation technology is considered virtually maintenance free, so the maintenance requirements are only related to periodical checks to make sure that the system operates correctly.
