Lightning Protection Solutions - ERICO
expensive surge protective device (SPD) will not function properly without a good grounding system. A low-impedance grounding system may create hazards to personnel and equipment without proper bonding. These interdependent disciplines are best applied when considering a total facility, rather than an individual portion. Evaluates risk,

Cathodic Protection Connections - ERICO
www.nvent.comProtection leads to pipes (steel or cast iron), tanks and structures. Cadweld connections weld the conductors and the structure to be protected so no galvanic corrosion can occur at the interface. The Cadweld process is specifically formulated to provide minimum heat effect on steel, which is especially important on thin-wall, high-stress pipes.
