EX grounding cables
High-quality EX grounding cables are essential in areas with high electrostatic fields, such as laboratories, factories, server rooms, and transportation. In particular, electrostatic grounding plays a key role in ensuring safety during the transport of fuels and chemicals in tankers, both by train and truck. Without proper grounding, sparks caused by the accumulation of electrostatic charges can lead to explosions and fires, posing a serious threat to life and property.
When selecting the right grounding cables, it is important to consider their strength, conductivity, and compliance with safety standards. Investing in an effective electrostatic grounding system is crucial to ensuring the reliability and safety of operations in various industries, including the transportation and logistics of hazardous materials.
1. Cable selection
The cross-section of the grounding conductor should be appropriate for the expected short-circuit current and should meet the requirements of standards such as PN-EN 62305. Grounding conductors should be made of highly conductive materials such as copper, aluminum, or their alloys, which are resistant to corrosion and mechanical damage.
2. Installation of cables
Grounding wires should be routed along the shortest possible path to the grounding point in order to minimize impedance. The wires should be secured in a stable and durable manner, avoiding mechanical stress and bending that could lead to damage. In areas exposed to mechanical damage, the cables should be protected, e.g., by placing them in protective covers or pipes.
3. Corrosion protection
In environments exposed to corrosive factors, cables should be properly insulated and protected against corrosion. It is preferable to use corrosion-resistant materials such as copper or aluminum, as well as protective coatings.
4. Connections
All grounding conductor connections must be secure, durable, and corrosion-resistant. Connections may be made by welding, soldering, crimping, or bolting. After installing the connections, electrical continuity tests must be performed to ensure that the grounding conductor is properly connected.
5. Inspection and maintenance
Grounding wires should be regularly inspected for technical condition, electrical continuity, and absence of corrosion or mechanical damage. If damage is found, the wires should be repaired or replaced immediately.
6. Compliance with standards and regulations
The installation of grounding conductors must comply with applicable standards and regulations, such as PN-EN 62305 (lightning protection) and local building and electrical codes.
7. Special conditions
In special environmental conditions, such as explosion hazard zones, humid environments, or locations with high salinity, special cables and additional protective measures may be required.
