Here I wanted to share information on how the earthing of communication tower is done/ Earthing of communication tower is necessary for safety of building or houses against disaster of naturally occurring lighting and thunders. I am working on a WISP(Wireless Internet Service Provider) project where I have to erect a 6m sector-ed antenna tower which I had shared information about in the blog post WISP tower construction.For this a good earthing is required. Here I will share some of my knowledge and experiences. I have listed the materials that we have used here and a step by step guide to how to earthen a communication tower. And a video of the complete earthing installation is also provided.
Below is picture that shows the view of how after earthing it looks like.
We have to buy a package for the earthing which consisted of the following materials required for earthing and grounding.
1. Earthing rod
The rod length used was 1.5m and the rod was filled with some kind of chemicals which I have not yet learn about.
2. Pit Plastic Cover
3. Earthing Chemical Compound
4. A regular electrical hollow pipe for underground to insert earthing cable
These materials are shown in the picture below.
The steps of earthing of communication tower are as follows:
Step 1: Dig a hole according to the length and size of the earthing rod
Step 2: Insert the earthing rod into the hole
Step 4: Fill the space around the rod with the mixed earthing compound.
Step 5: Create a underground passage by digging a hole and placing an electrical protective hollow pipe to connect the electrical grounding cable to the grounding rod tip where there is connection hole for the earthing cable.
Step 6: Cover the remaining hole with the mud and place the plastic earthing cover onto top of the grounding rod
Watch the following video that shows completed installation of the earthing rod, digging hole, pouring earthing compound etc.
Later on the earthing cable coming from the tower will be inserted and connected to the earthing rod through the electrical hollow pipe. I will update once I have connected the earthing cable to the tower and the earthing rod. Then my WISP network will be almost ready for a test.
