Product Detail

General


FZN63 series load break switch and its combination electric appliance are digested and absorbed by foreign advanced technology, and combined with the requirements of our users, they are designed and developed by our factory. It is a new generation of high-voltage electrical products suitable for the transformation and construction of urban power grids. The performance complies with GB/T3804 "3-6KV AC high voltage load switch" and GB/T16926 "AC high voltage load switch-fuse combination electric appliance" standard. The product is entrusted to the National High Voltage Electric Quality Supervision and Inspection Center Xi'an High Voltage Electric Apparatus Research Institute according to the latest national standards. Comprehensive type test, the main technical parameters have been the leading level of similar products in China. This product is widely used in factories, schools, residential quarters, high-rise buildings and other three-phase AC, system voltage 3.6-12KV rated frequency 50Hz power distribution system, as a means of receiving and distributing electrical energy, can be used for ring network switchgear, box-type substation , switching equipment and other power distribution equipment.
