Strengthen the protection device of communication optical cable joint

摘要

The practical model belongs to the field of electrical engineering, and can be used for the protection of communication optical cable in active lightning activity area.;In order to solve the protection task of optical cable in high thunderstorm area, a lightning protection device for optical cable is proposed Metal elements,The building length is connected by a connecting sleeve,Use lightning cableHalf the depth of the cable is laid on it,Its axis coincides with the axis of the optical cable in the vertical plane.;Improve the efficiency of optical cable lightning protection,On the lightning cable at the joint of the construction length of the optical cable, the connecting sleeve is used to be perpendicular to the track on the horizontal plane of the inlet and outlet Cable laying line grounding device for connecting sleeve,Its length is equal to the depth of the cable. At the intersection of lightning cable and each line grounding devicebody contact. The connection between the line grounding device and the lightning cable ensures the connection at one end of the line grounding deviceOn one side of the cable there is a connector ground,In addition, a vertical grounding device is introduced at the end of each linear grounding device.
