Earthing straps, also known as earthing cables or earthing strips, are used to safely earth electrical devices, systems or buildings and thus protect them from electrical surges.
Earthing straps are usually installed by electricians or earthing system specialists. Here are the basic steps:
1. planning: first, a thorough analysis of the requirements and local conditions is carried out. The objects to be earthed, the length of the earthing strap and the appropriate route are determined.
2. material selection: Suitable earthing straps and accessories are selected that meet the local requirements and standards. Earthing straps are made of copper or aluminum and have a special coating to prevent corrosion.
3. installation: The earthing strap is installed along the specified route. It is usually laid in a trench or on the surface of the ground. It can also be attached to building structures, metal pipes or other conductive elements to ensure earthing.
4. connection: The earthing strap is connected to the objects to be earthed, such as electrical installations, machines or metal structures. Special clamps or clips are used to create a secure and permanent connection.
5. verification: After installation, the effectiveness of the earthing is checked to ensure that it complies with the required standards and functions properly. Measurements are taken to determine the resistance of the earthing connection and to ensure that it is within the permissible limits.
Earthing straps are an important part of the electrical safety system and help to protect people and equipment from dangerous electrical voltages. It is important that they are properly installed and maintained to ensure safe and reliable earthing.
