AC Interference in Shared Corridors

Equipotential Bonding in Hazardous Areas

equipements

Effective equipotential bonding is required for all electrical equipment installed. This also applies to systems that are located in potentially explosive atmospheres. The equipotential bonding system eliminates potential differences and thus prevents dangerous touch voltages. The potential conductor itself must not generate any ignition sparks.

Bonding in Large Industrial Facilities

industrial

Bonding in large industrial facilities is a critical safety and corrosion control practice that ensures electrical continuity between metallic structures, equipment, pipelines, storage tanks, cable trays, and structural steel. Proper bonding minimizes potential differences, reduces the risk of stray current corrosion, and prevents hazardous spark formation in sensitive environments such as oil & gas plants, refineries, tank farms, and power stations.
