Indoor H.V. Load Break Switch ZFN16-12 Series
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 load, overload 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.
