FZN21 Series Vacuum Load Break Switch, 12KV, 630A, Spring Operating
FZN21-12DT630-20: High Voltage Load Switch with Excellent Reliability and Low Maintenance
The FZN21-12DT630-20 load switch is a great way to control and protect load current interruption in high voltage networks. The load switch can operate frequently and does not require any maintenance, which goes beyond the normal expectations of high voltage network systems. The use of vacuum technology in its load interruption mechanism provides reliability and durability in operations, thus giving the FZN21-12DT630-20 a longer operational life. The use of vacuum conditions reduces the likelihood of arcing, and provides for a much more safe and clean load interruption, which is essential for creating a maintenance free and environmentally friendly power system.
Flexibility for Frequent Operations
The design of the FZN21-12DT630-20 is such that it can handle frequent operations with ease. The load switch has been specially designed for repeated cycling against dynamic and changing electrical loads. This flexibility enables continuous operation without any interruption and is essential for facilities that need to have a constant supply of electricity. By strategically placing the load switch in electrical substations, it improves the overall reliability and performance of a power network and is therefore not surprisingly, one of the most widely used load switches in industrial and commercial applications.
An interesting outgrowth of the technology used by the FZN21-12D indoor high voltage vacuum AC load switch-breaker combination device is that it incorporates into a single unit the switching function and the circuit-breaking function of the previously developed FZN21-12DT630-20 indoor high voltage AC vacuum load switch. Also like its predecessor, it is designed for three-phase AC networks at 12kV, has no oil required for operation and, when operated in a normal manner, does not need to be serviced. In addition to simplifying the installation requirements for an electrical system, combining the two devices into one means much less space and much less money will be spent on additional Circuit Breakers; thus, by combining two functions in one electrical device, a new way to create electrical networks with large numbers of circuit breakers is offered.
To conclude, the FZN21-12DT630-20 along with the FZRN21-12D indoor high voltage AC vacuum load switch and combination device is a prime example of modern-day electrical engineering. Their oil-free, maintenance-free design combined with their rugged, heavy-duty construction make them essential pieces of equipment for any modern power grid with an essential need to operate 24/7 without sacrificing safety or efficiency. Organizations that purchase high quality equipment like this can raise their operational level by providing all of the necessary components for long-term reliability and outstanding performance of their high voltage power networks. Having these technologies in place today will not only increase the capacity of operations today but will also enable the growth and future expansion of infrastructure to meet the growing needs of electrical distribution networks.
