One, what are the specifications of the grounding wire
The specifications of the grounding wire are as follows:
1, 380v grounding wire, 500v grounding wire, 6kv grounding wire, the length of the operating rod is 50CM.
2, 10KV grounding wire operating rod length of 1 meter.
3, 35KV grounding line insulation operating rod length 1.5 meters.
4, 110KV grounding line insulated operating rod length 2 meters.
5, 220KV grounding line insulation rod length 2.5 meters.
6, 500KV grounding line insulation rod length 8 meters.
Second, the role of the grounding wire what
1, the protection of personal safety
Because static electricity in the discharge process will produce a charge, if the electrical equipment is not well isolated, it is easy to electrical appliances and the human body caused by the injury, and the role of the grounding wire for the purpose of high-voltage equipment and the earth's conductor, to avoid the damage to us by the electric charge.
2, lightning
In the past, if there is thunder and rain, poles and other equipment will be damaged because of lightning strikes, some may not be able to use for several days, so the grounding wire is to prevent lightning, increase the role of protection, can extend the service life of electrical equipment.
3, to ensure normal operation
Some equipment must have electricity to work, such as: medical work, grounding wire is to avoid power outages encountered when the unexpected situation, will not be affected, you can carry out normal operation of a small load reference potential.
4, to prevent strong electricity and lightning communications equipment
For example, columns and general communications equipment chassis grounding, to prevent equipment, instrumentation, personal injury, therefore, the role of the grounding wire is still very large, but also often overlooked, we need to pay attention.
Article Summary: The above is what I share with you the specifications of the grounding wire, as well as the role of the grounding wire what relevant content, I hope to give you some help. Home decoration must be grounded wire, so that it can play a role in lightning protection, to protect personal safety.
