● The LY series lightning protection boxes are designed in accordance with IEC and national standards. Equipped with lightning protection failure indication, grounding failure indication and automatic disconnection protection components for SPD failure, the product adopts high-efficiency lightning protection modules as core components. With a discharge capacity ranging from 20kA to 80kA, its voltage protection level is lower than 2.5kV under rated operation, and the lightning discharge response time is less than 25ns. It can effectively suppress lightning and various transient overvoltages in circuits to reliably protect all kinds of electronic equipment.
● Featuring excellent lightning protection performance, the LY series lightning protection boxes are applicable to single-phase / three-phase power supply systems, and widely used in occasions requiring high-level lightning protection for protected equipment.
● The LY series lightning protection boxes support wall-mounted installation, which is ideal for sites with limited installation space inside distribution cabinets.
The product is assembled with three-phase power surge protective devices, SPD backup protectors and other components. It complies with the Class II test specifications of GB18802.1-2011 Low-voltage surge protective devices (SPD) — Part 1: Performance requirements and test methods for low-voltage power distribution systems. In accordance with GB50057-2010 Code for design of building lightning protection, it is applied to the primary and secondary lightning protection and anti-surge protection design of power lines.
