Product Description
FZW28-12F Type Outdoor AC Boundary Vacuum Load Switch
Product Overviews
Apply to rated voltage 12KV. Rated frequency 50HZ outdoor AC distribution equipment , use for opening .closing load current and closing short circuit current . Applicable to substations and industrial and mining enterprises and city, rural network for protection and control purposes, and city, rural network automatic distribution net and frequent operation place .
Applicable to operation of control switch of overhead line distribution systems, there are several types, VPS-12-type boundaries vacuum load switch with no oil, institutional simple. Reliable, no maintenance and other advantages, has been widely used. The product with the FDR-based fault detector or RTU remote terminal unit equipment combine to form a very simple structure, distribution automation system that allows the automatic overhead lines fault location and fault segment of the automatic quarantine. In order to update our existing distribution switchgear, so free of oil and automation features of the distribution equipment for the transformation.
