Transmission system lightning arrester , high and low voltage surge protection device
Product Details
Surge protector lightning protector is used to protect sensitive lines from lightning induction voltage, power grid voltage fluctuation, electrostatic discharge and surge voltage caused by large load start-up. It is widely used in family housing, third industry and industrial field.
Structure and Principle
SPD is a port, shocking protection, indoor-mounted installation, voltage-limited.
SPD hold disconnector inside, when SPD breakdown failure by over heating, the disconnector can remove from the power grid automatically, and show indication signal. When SPD is working properly, visible window display green, it display red when it breakdown and disconnect.
1P+N,2P+N,3P+N SPD consist of 1P,2P,3P SPD+NPE zero ground protection module, apply to TN-S, TN-C-S and other power supply system.

Product features
1. safety insulation of fire retardant and high flame retardant material
2. self protection voltage is more than self protection, automatic disconnection and recovery.
3. limit the precision of the voltage to say how much!
4. detachable assembly and pluggable convenience
Notice of product
1. 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.
2. identify the input / output interface identifier of the lightning protector, input the external line and output the connection device.
3. connect the grounding wire of the lightning protector with the ground wire of the lightning protection system.
4. after correct installation, it can work steadily for a long time. If it is found that the transmission performance of the system is reduced or the signal is interrupted due to the cause of surge protection, it should be maintained or replaced in time.
Working principle of product
The function of surge protector is to limit the transient overvoltage to the power line, the signal transmission line in the voltage range that the equipment or system can bear, or to inflow the powerful lightning discharge into the ground, and protect the protected equipment or system from damage by the impact.
