SPD is used to protect all kinds of electrical equipment in the power system from lightning over-voltage, operation over-voltage, power frequency transient over-voltage impact damage to an electrical appliance
The electrical circuit or communication lines because of outside interference peak current or voltage suddenly, the surge protector can in a very short time conducting shunt, so as to avoid damage to other equipment surge in the loop Installed front of inverter input and back of inverter output Installed in Parallel the spd is installed in the electric circuit with parallel, the first to play a protective role, the response time in the 25 to 50 nanosecond

Installation requirements
Surge protector using 35MM standard rail installation
For fixed SPD, the conventional installation should follow the following steps.
1)Determine the discharge current path
(2) mark the additional voltage drop caused by the wire at the end of the equipment,.
3) To avoid unnecessary induction loops, the PE conductor of each device should be marked.
(4) the establishment of equipotential connection between the equipment and SPD.
5) To carry out energy coordination of multi-level SPD
In order to limit the protected part after installation and unprotected

Q1: Selection of surge protector
Al: The level of surge protector (commonly known as lightning protection) is evaluated based on the IEC61024 subdivision lightning protection theory installed at the junction of the partition. The technical requirements and functions are different. The first level lightning protection device is installed between zones 0-1, and the flow requirements are very high. The minimum requirement of GB50057 is 12.5 ka (10/350), and the second and third levels are installed between 1-2 and. 2-3 areas, mainly to suppress overvoltage.
Q2: Are you a lightning protector factory or a lightning protector from a trading company?
A2: We are a manufacturer of lightning surge protectors.
Q3: Warranty and return?
A3: 1. Lightning surge protector products and accessories have been tested 3 times before leaving the factory. 2. We have the best after-sales service team. If there is any problem, our team will do our best to solve it for you.
Q4: How to get some samples of surge protector?
A4r: We are honored to provide you with samples of lightning protection devices. Please contact our staff and leave detailed contact information. We guarantee to keep your information confidential.
