100KA equipotential connector



1.   Product introduction:

LK-DDW100K equipotential connector is open state in normal situation to insulate mutual interface based on different grounding body and avoid grounding inequality. It can prevent that ground potential beat back damage device.

2. Performance:

● Two nearer independent earth pole protection.

● Fast discharge ability

● Complete arc extinction ability ,no power frequency follow current.

● Simple installation, can be applicable to indoor and outdoor moist underground environment.

Working principle:

When the potential difference of LK-DDW100K equipotential both ends is higher than breakdown voltage, which  urges different ground connection potential of connector both ends to equal and won’t happen grounding body discharge to avoid grounding potential inequality ,personal and device safe.

LK-DDW100K equipotential connector application range:

1. When there are many types earth screens such as safety earth, logic earth,weak current earth, heavy current earth or SPD earth and these earth screens can’t unify

2. When the distance between two earth screens is less than 20 meters, they can effect each other.

3. Some special devices cannot connect earth directly, for safety ,they need install SPD ,SPD need  ground connection.

4. After contacting ground, some devices’ signal are disturbed by unclean ground system ,which will cause device’s abnormality.

Notice:

Equipotential connector need check one time every year or check any time according to request
