According to the needs of the site, special grounding clamps are used for grounding, and the grounding clamps commonly used now (see Figure 1) have a door frame There are two shrapnels in the frame to form the clip body. During operation, connect the ground wire to the ground wire column of the ground wire clip, and then hang the ground wire clip on the cable, but because the lower end of the ground wire clip is open The grounding wire clamp is easy to fall off under the action of external force, and the shrapnel on the clamp body is also easily damaged, so that the clamping force of the clamp body is not strong enough to cause it to fall off.
