AC Electrical Power Surge Protection Device 40KA IMAX Against Lightning Fluctuations
Brief introduction
The surge protector is a voltage switch type SPD fixed to the indoor outlet for one port, and the product is designed and manufactured according to the current national standards such as GB50057-2010 and gb18802.1. It has the advantages of large impact current and low residual pressure. The core components are composed of multistage graphite gap. Reasonable design and precise processing of the combination of spark and twisting together form a sealing mechanism to ensure the safe distance of the spark gap. Even when the surge current is passed, it will not produce the arc discharge.

Working principle of product
Power surge protector is divided into two parts: explosion proof box type and modular type. A varistor with excellent nonlinear characteristics is adopted. Under normal conditions, the surge protector is in extremely high resistance state, and the leakage current is almost zero, thus ensuring the normal power supply of the power supply system. When the power system surge overvoltage, the power surge protector immediately passes in the nanosecond time, limits the amplitude of the overvoltage to the safe working range of the equipment, and releases the surge energy into the ground. Subsequently, surge protector rapidly changes to high resistance state, so that normal power supply is not affected.
Use of attention
1. the protected equipment must have good grounding, and the grounding impedance is in accordance with the relevant national standards.
2. standard RJ45 interface can be conveniently connected to the front end of the protected equipment. The grounding path should be as short as possible, and the length should not exceed 1.5 meters.
3. generally speaking, it is better to separate the protected conductor from the non protected conductor, and it should be separated from the ground wire. At the same time, in order to avoid transient orthogonal coupling between power cables and communication cables, necessary measurements should be made.
