Product performance and technical indicators:

1. Overview

LSD-QX-III spherical current limiting lightning rod is a new type of external lightning protection device for preventing direct lightning strikes, and is an important innovation in the field of modern lightning protection technology. This product not only has the same function as the traditional lightning rod to lead lightning into the ground, but also can reduce the amplitude of lightning current, extend the discharge time, and reduce the steepness, so as to effectively inhibit and weaken the harm caused by the ground potential counterattack and secondary lightning stroke effect. Therefore, this product can provide reliable lightning protection security for today's information technology, network technology, microelectronics technology, and weak current equipment. This product has advanced design, novel structure, lightweight, and easy installation, and has a decorative effect on buildings. Suitable for buildings, constructions, broadcasting, communication, meteorology, airports, ports, petrochemicals, storage and other important places.

2. Working principle

The LSD-QX-III spherical current limiting lightning rod, in its working state, conducts the large current generated by lightning strikes to the internal current limiting impedance device through the lightning receiving needle tip, and reduces the amplitude and steepness of the lightning current through the unique lightning peak suppression function of the device, effectively weakening and suppressing the harm caused by ground potential counterattack and secondary lightning strike effects.
