Offered range of hollow copper lightning arresters is useful for safeguarding insulator and conductor of telecommunication equipment and electric power generation system against lightning. Suitable for three phase power system, this array of hollow copper lightning arresters is equipped with a ground terminal and a high voltage terminal. As part of the mechanism of these lighting arrestor, electrical surge that comes from the power line tends to divert through these arresters to the earths ground to avoid damage to public life and property. Available in copper bonded design, these lightning arrestors are reckoned for their exceptional strength and low maintenance design.
