Lightning Protection

The new high-voltage-resistant insulated HVI light plus Conductor has been tested with regard to its lightning current carrying capability and impulse withstand voltage both as a single conductor and as a system in accordance with IEC/TS 62561-8 and offers simplified design options. The insulation measurement is conducted with 1 kV or 15 kV. Cable installations, pipe systems or metal parts are frequently installed under the roofing in direct proximity to the air-termination system / down conductor, thus posing a proximity issue. The solution is isolated air-termination systems with high-voltage-resistant, insulated down conductors. The coaxially constructed HVI light plus Conductor consists of a solid inner conductor with a thick-walled, high-voltage-resistant insulation and asemi-conductive outer sheath. This design allows the HVI light plus to maintain an equivalent separation distance in air of 60 cm to earthed metal building installations without creepage discharge. This prevents uncontrolled flashover and channels lightning current directly to the earthing system. The lightning current carrying capability of the HVI light plus is 150 kA and it can be used in lightning protection classes II, III and IV at kc = 1. Equipotential bonding is established without the need for an additional equipotential bonding connection. The grey outer sheath protects against electric shock. In line with test standard IEC 60060-1. The HVI light plus also has Ex approval and can be used in hazardous areas of Ex zones 1 (gases, vapours, mists) and 21 (dusts). The HVI light plus is halogen-free and has fire class Eca.
