200 kA clamps For classes of LPS I and II The new 200 kA clamps from DEHN meet high requirements. According to the IEC 62561-x standard series, connection components must meet certain mechanical and electrical requirements. In tests according to IEC 62561-1, they are subjected to ageing and an electrical test with three lightning current impulses of 10/350 µs wave form each*. Depending on the lightning current carrying capability, a distinction is made between • Class N: 50 kA (normal duty) and • Class H: 100 kA (high duty). DEHN offers connection components with a lightning current carrying capability of 200 kA (10/350 µs) based on the IEC 62561-1 standard*. Connection components tested according to this standard can be used for class III/VI lightning protection systems and if the lightning current is distributed in a meshed lightning protection system. In case of class I/II lightning protection systems, the lightning current is poorly distributed or not distributed at all if air-termination rods are connected to existing mesh systems. If an air-termination rod is connected to a mesh/roof parapet by means of a single conductor, 100% of the lightning current will flow from the air-termination rod via the connection components. The case is similar for HVI®Conductors or HVI®power Conductors without current distribution used for class I/II lightning protection systems. When conducting the lightning current from the high-voltage-resistant, insulated down conductor to the existing lightning protection system, the clamps/connectors are exposed to 100% of the lightning current. This would be 150 kA in case of a class II lightning protection system and 200 kA in case of a class I lightning protection system. The “200 kA” imprint is characteristic of the new components. The 200 kA components are fitted with a spring washer for use in Ex zone 2/22**.
