Three introductions about the lightning protection box, an introduction to the lightning protection box, the picture of the second lightning protection box, and the application range of the three lightning protection boxes.
Introduction of lightning protection box
The most common is the power lightning protection box, the power lightning protection box mainly has a sealed power supply lightning protection box, the door type power supply lightning protection box, the explosion-proof power supply lightning protection box, the distribution power supply lightning protection box, the matrix power supply lightning protection box Wait.
According to the use environment, it can be divided into: outdoor power lightning protection box and indoor power lightning protection box.
According to the connection method, it can be divided into: series type and parallel type.
Note: All lightning protection boxes must have reliable grounding!

Lightning protection box application range
The lightning protection box module is composed of a voltage switching module and a voltage limiting module (or an integrated MOV). It is mainly installed in power distribution rooms, power distribution cabinets, AC power distribution boards, switch boxes and other important equipment, and power supply lines that are vulnerable to lightning strike equipment to protect equipment from lightning damage caused by lightning surges along the power line; It can be widely used in main power protection of communication, power, transportation, finance, railway, civil aviation and other systems.
·Composite power supply lightning protection box is widely used in lightning protection and overvoltage protection of main power supply for communication, power, mine, finance, civil aviation, railway and other systems;
· The total distribution screen of the building, the distribution cabinet, the distribution box, and the environment where the first-level lightning protection facilities shall be installed;
· Unmanned but required to install the first level of lightning protection equipment with remote signaling instructions; need to have first-level lightning protection failure indication and alarm indication and lightning discharge recording environment;
· Small area but requires two levels of surge protection
In the communications industry, the main differences between using modules and boxes are:
The advantages of the modular arrester: 1, cheap, a single module about several hundred dollars; 2, compact, volume and small air switch, 3, easy to install, use standard rail installation;
The advantages of the box type arrester: 1. The fireproof ratio is better than the modular type, especially for the unattended base station; 2, part of the performance is higher than the modular type, especially the series type, the limiting voltage is low, the anti-defense The effect of surge voltage is much better.
Hex nuts are also called hexagon nuts. Generally, there are many kinds of nuts, including hexagon nuts, round nuts, square nuts, flange nuts etc. Some standards for nuts are quite clear. Some specifications and size standards, material requirements and standards, and electroplating standards are quite clear. Different kinds of nuts also have different standards. And also they have many materials, we mainly do stainless steel hex nuts. stainless steel often has a very good quality for use.
