LDY-CATV network lightning protection devices are applicable to the lightning and overvoltage protection of CATV devices, such as amplifier, receiver, etc. which also can be used to protect the signal channel of the television. (Option from standard IEC61643-21 and GB50343)

• High current capacity, low residual voltage
• Having two class protection (B+C)，strong protection ability, high reliable performance.
• Various conductor for selection, strong adaptability ability.
• Modularization design, free grounding, convenient for installation and replacement.
• Installation in series, providing omnibearing protection covering signal channel, and all-protection covering phase line and central line, introducing inner potential balance principal, free grounding, repeatedly used after several lightning.
