Specification

1.Highest voltage for equipment can be up to 40.5 kV.

2.Maximum prospective fault current 5.0 kA

3.Lightning discharge capability 2.8 C

4.Installation 1, 2 or 3 pcs per pole

5.Protects from Direct Lightning Strike (DLS)

6.Protects from Back Flashover (BFO)

7.No maintenance is required



Usage and Expected Lifespan

1.This device is designed to protect power supply networks from the consequences of either direct lightning strikes or induced overvoltages. Indented to be installed along the protected line, it works perfectly on distribution lines with the highest voltage of equipment up to 40.5 kV.

2.The expected lifespan is up to decades.



Operational Principle

MLPD35-D can easily be adapted to any cross-arm or pole configuration. This is possible due to different attaching solutions and accessories available.
