There is a built-in induction-free lightning protector of B+C level in the AC
input part of the ZXG10 OB06 system, while the internal modules of the
power system provides a lightning-protection function of D level, thus
preventing faults in most cases of lightning.
A 1/4 wavelength lightning-protector is used for the antenna system,
installed at outlet of the antenna feeder in a position near the cabinet. The
lightning protector is effective in preventing the antenna from suffering
damage by lightning.
ZXG10 OB06 supports E1 transmission access. At the access interface of
E1 there is a B-level signal lightning protector, and the internal E1
interface boards all support a D-level lightning-protection function, thus
capable of preventing damage by lightning and surge.
All components inside the cabinet are well connected through metal screws;
good grounding terminals are available and protection ground cables are
well installed.
