LDY-10D Series

LDY-10D series are applied to equipotential bonding of the low voltage distribution boxes in the building, providing protection against the overvoltage arising from the lightning strike to the power supply system of class 4 or faulty operation.(option from standard IEC61643-1 and Gb50343)

LDY-40B Series

LDY-40B series are applied to equipotential bonding of the main low voltage distribution boxes in the building, providing protection against the overvoltage arising from the lightning strike to power supply system of class 2 or faulty operation.(option from standard IEC61643-1 and Gb50343)

LDY-POE

LDY-POE series are applied to network device powered by the CAT-5E,which is usually installed at the junction of LPZ1-LPZ3 of lightning protection zone, with function of two classes protection. These series can prevent the network device from damage caused by the overvoltage and overcurrent arising from lightning strike and industrial interference, so they are widely used in the wireless network bridge device.

LDY-BNC Series

LDY-BNC series video signal lightning protection devices are applicable to coaxial transmission device applied in main thin cables, thick cable, network wire, CATV, video monitoring device, public television, satellite television receiver and VOD system, etc. which can prevent the system equipment from the permanent damage or transient interruption arising from inductive overvoltage, overcurrent and the other transient surge voltage caused by lightning or industrial noise, etc.

LDY-40B Series Surge Protective Box

These series are applied to equipotential bonding of the low voltage main or distribution boxes in the building, providing protection against the overvoltage arising from the lightning strike to power supply or faulty operation.(option from standard IEC61643-1 and GB50343)

LDY-D Series

LDY-D Series earth pole protection device is mainly applied to avoid the danger of potential difference between different grounding grids. When lighting comes. as the short distance among different grounding grids, the ground potential of some grounding grid may be elevated high simultaneously, thus high potential difference occur with other grounding grids, which may exist among network
