Overview
FNR12-12 series high voltage AC Vacuum load switch is applied in the three-phase, AC50Hz, rated voltage up to 12KV electric supplying network. The load switch and combination equipments own obvious isolation fractures, can match earthing switch of CO capacity and electric spring mechanism.
Product Details
Introduction
FN12 series high voltage out door circuit breaker can be used for 50HZ 40. 5kv outdoor high voltage electrical equipment.
Attached spring operating structure and electromagnet operating structure can manipulate electric opening and closing in a distance, or accumulate energy for manual operation.
Mainly used in controlling and protection of outdoor power transmission and transformation system of 35kv, also in normal operation and short-circuit protection for all kinds of power grid and frequent operation place.
It has characteristics of well tightness and high temperature endurance, non-combustion and non-exploration, easy mounting, anti-aging and long service life.
