In the embodiment of the invention, the lightning protection component 1 is clamped on a cable, the cable is placed on a cross arm, and the cross arm is installed on a telegraph pole.
It should be appreciated that the metal conductive plate has a receiving cavity for receiving a cable, which is a portion of receiving a cable laid on a utility pole. When the rain water storage device is stored, the opening of the storage cavity faces away from the sky, so that the rain water storage device has the advantage that rainwater is prevented from being stored in the storage cavity.
Optionally, in some embodiments, the insulating member 12 is bonded to the metal conductive plate.
In one embodiment, when the metal conductive member 11 is laid on the cable and is struck by lightning, the metal conductive member 11 is grounded, and the current generated by the lightning strike on the surface of the metal conductive member is conducted to the ground.
In another embodiment, when the metal conductive piece 11 is laid on the cable and is struck by lightning, the metal conductive piece 11 directly receives the lightning and may be damaged, for example, the cost for replacing the new lightning protection component 1 by damage is lower than that for replacing the cable, and the replacement is more convenient, so that stable power supply can be ensured.
It will be appreciated that the insulating member 12 serves to insulate the metal conductive plate from the cable when mounted thereto, such that current on the metal conductive plate is not transferred to the cable in the event of a lightning strike.

It should be noted that all the insulation protrusions 121 within a set of insulation protrusions 121 are located in the same circumferential direction of the cable.
As shown in fig. 4, the insulating protrusions 121 may be further configured such that one or more notch grooves 122 are provided on one insulating protrusion 121, which may be provided to facilitate heat dissipation and reduce the weight of the lightning protection member 1.
