Detailed info for cathodic protection specialists

Show specialist knowledge – offer competent advice


In most cases, it is the cathodic protection specialist or the plant construction firm that makes the operator aware of the need for a comprehensive lightning protection concept. Many operators are also thankful for practical information regarding safety equipment and arc-fault protection.


That means: the more you know, the better your advice. There are much fewer wrong deliveries and problems for the customer with the initial operation. This saves you time, money and hassle … and, in the long-term, your image profits from it, too.


Be a competent and reliable partner for your customers.
