■ HVEW-12Fuses vacuumarc control and SF6 gas insulation. Its arc control performance and resistance are superior.

■ The main circuit of switch and the operation mechanism are sealed in the box that SF6 gas as the medium, whose

outlet and inlet lines adopt cable head or tube to lead out without maintenance.

■ The top of switching box is equipped with explosion-proof device and SF6 gas pressure inside is regarded as zero

gauge pressure. By this reliable seal technology, the products would obtain high securityand reliability.

■ HVEW-12Fpossesses intelligent distribution interfaces, which can be equipped with all kinds of current transformer for

measurement, protection and calculation, as well as can be equipped with a remote auxiliary contact.
