Easy to build surge protector, no need to connect additional cables or decoupling coil to realize the energy coordination with the secondary surge protector. Widely used in wind power supply system, low-voltage equipment protection of buildings, AC side of photovoltaic power generation system, communication base stations, generator sets, data center power system, etc., greatly improving the reliability and safety of electrical equipment.

YSPD-25HA series applies easy-to-manufacture patented technology to realize excellent performance such as high sustained operating voltage, no renewal current, low voltage protection level, etc., with unique functions of disconnection, local and remote alarm.

YSPD…. .320 series of composite primary surge protector with patented technology, with a maximum of 100kA (10/350μs) lightning current discharge capacity, no renewal, can directly protect the terminal equipment, etc., which represents the world’s highest level of technology. This series of products is ultra-small, each phase is only a modulus wide (18mm); with the main circuit release technology, to ensure the high reliability of the equipment and low risk; its local and remote alarms to provide real-time on-line status monitoring; no continuation of the current technology to ensure the high reliability of the power grid system and so on.

Composite surge protectors are usually installed in lightning protection partition LPZ0B-2.
