ZFN 16-12 series indoor H.V.load switch

ZFN 16-12 series indoor H.V.load switch Features Specifications: ZFN16-12 Series Indoor H.V. Load Switch

ZFN16-12 Series Indoor H.V. Load Switch

Summary  It is designed and developed by ourselves. Its performances reach international and national standard in GB3604-90 <<3-63KV AC H.V. Load Switch>> and IE420 <<AC H.V. Load Switch with Fuse>> (1990 Edition), with the features of safe breakinglong power lift-timefrequent operationobvious isolating break and break transfer current without maintain, The load switch with fuse box have also protects transformer against over-load and working without phase.Application  ZFN16-12 Series Switch is used in the network of rated voltage 6-12 KV and three-phase AC 50Hz for breaking loadoverload and short-circuit current, esp. for the requirement of frequent operation but without oilization and repair.  The product is equipped with CS6- I type operating mechanism and CS handle operating mechanism. Service conditiona. The altitude does not exceed 1000m.b. The ambient air temperature: Max.: +40 . Min: -25 .c. The relatire humidity of air. daily average ≤ 90%. monthly average ≤ 95%.d. The ambient air should not be obviously polluted by corrosivity or the flammability gas and steam. etc.e. The working situation without frequent violent.Technical parameter and performances
