Earth Wire

Earth Wire is used as the medium to transfer the leakage of current if any from metallic body to the earth to prevent the shock.


Advantages

Protection against electric overload
Prevents damages and injury

Features

Galvanizing prevents and reduces rusting of the base steel.
Flexible then normal steel wire.
