Power Transmission System Lightning Protection Device Three-phase
lightning protection device
Product introduction
Surge protector is an electronic device that provides security
protection for all kinds of electronic devices, instruments and
communication lines. For AC 50/60HZ, the power supply system with
rated voltage to 380V is protected by indirect lightning and direct
lightning impact or other instantaneous overvoltage surge. It is
suitable for household housing, third industry and industrial surge
protection, with relative, relative, middle line, middle line and
its combination. Protect the model.

Product features
1. the temperature control protection circuit is adopted, and the
thermal protection is built.
2. with the power status indication, indicating the working state
of surge protector.
3. alarm indicating device, normal (green), red (fault).
4. detachable assembly and pluggable convenience
Notice of product
1. identify the input / output interface identifier of the
lightning protector, input the external line and output the
connection device.
2. grounding lines should be short, thick and straight, so as to
reduce the influence of distributed inductors on the ability of
lightning electromagnetic pulse.
3. marking the extra voltage drop caused by device terminals.
4.The establishment of equipotential connection between devices and
SPD
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.
