Grounding clamps are used to dissipate electrostatic charges from metal tanks, drums, mixers and tankers during the loading and unloading process. Their purpose is to provide a permanent connection between the grounded component and earth, preventing the build-up of electrostatic charge and minimizing the risk of explosion or fire.
Grounding clamps usually come complete with a grounding spiral cable. The clamp is made of stainless steel and has very sharp teeth that pierce through a layer of paint or rust, providing a permanent connection to the metal surface. The grounding cable is made of copper or steel, which is a good conductor. It is also insulated with a special coating that is resistant to many mechanical and chemical agents
During technological processes such as mixing, pouring or loading or unloading of tanks, grounding terminals should be fixed in dedicated locations. Depending on the type of process or safety requirements at a particular industrial plant, grounding clamps with wire alone or complete grounding systems that have grounding condition monitoring units in addition to the clamp and wire are used.
Grounding terminals are very important to ensure the safety of loading and unloading processes of tank cars and railroads, as well as other technological processes in which flammable substances are handled. All components to which the grounding terminal is connected must be in good condition to ensure a permanent connection and reliable discharge of static electricity. It is also important that grounding terminals are regularly inspected and replaced when they are damaged or defective.
Depending on the intended use, a distinction is made between:
- ex grounding terminals for tanks,
- ex grounding terminals for metal drums and containers,
- ex grounding terminals for IBC tanks and type C big bags,
- ex mini grounding terminals,
- ex magnetic grounding clamps.
Optionally, the terminal can be equipped with a nitrile rubber insulating shield to protect it from chemical agents and weather conditions. The shield is resistant to high temperatures and mineral oil-based substances.
In addition, we provide pins made of plastic for hanging the terminals. For the above applications, the terminals are connected to ground wires. They are also part of complete systems for monitoring the state of grounding.
