DC SPD is cost-effective and provides a solution to improve the system and eliminate any damage caused by surges. It is highly suitable for any facility. It can be used anywhere in the house for protection. These are installed on circuit breakers and automatic transfer switch for portable generator in residential homes and other places like pad-mounted transformers.
ZHEJIANG YUELONG offers and sells DC SPDs in 2 categories, type 1 and type 2.
Electrical networks are low-frequency and, as a result, propagation of the voltage wave is instantaneous relative to the frequency of the phenomenon: at any point of a conductor, the instantaneous voltage is the same. The lightning wave is a high-frequency phenomenon (several hundred kHz to a MHz): 1. The lightning wave is propagated along a […]
In today’s world, as electronics are increasingly used, the demand for surge protective devices is increasing. Surge protective devices are devices used to protect electrical equipment from damage caused by voltage surges, and they are an essential part of any electrical system. The development prospects of surge protective devices are very promising and have a […]
SPDis an indispensable device in the lightning protection of electronic equipment. Its function is to limit the instantaneous overvoltage entering the power line and signal transmission line within the voltage range that the equipment or system can withstand, or to discharge the strong lightning current into the ground. , to protect the protected equipment or […]
