ZQPT Arresters
Available for System Voltages Up to 345kV
Users of electricity have become more and more demanding over recent years. The quality of the power they receive is critical to their operations. Sensitive electronic equipment cannot tolerate voltage fluctuations and many problems are directed to the utility. The heightened awareness of power quality has brought the issue to all levels of operations including transmission.
In the area of transmission line power quality, MPS offers the "ZQPT" transmission line arrester. The lightweight construction makes it possible to easily mount arresters on the transmission line structures. The arresters provide a preferred path between line and ground, guarding against insulator flashover.
Surge protection of transmission lines is a solution to troublesome outages and customer dissatisfaction. State-of- the-art protection of transmission lines using polymer MOV arresters provides higher power quality, which will improve customer satisfaction.
"ZQPT" transmission line arresters are available for system voltages up to 345kV. The metal oxide blocks are specially selected and wrapped under compression with a strong fiberglass wrap.
