Description
Our Distribution Lightning Arresters have been designed and tested to meet our customers’ tough environmental conditions. Tests were carried out on these lightning arresters under the supervision of independent and accredited European test laboratories to meet the requirements of the latest edition of the IEC 60099-4 standard. They are manufactured using high-quality ZnO varistors, which display excellent thermal and current handling characteristics due to the guaranteed homogeneity of the varistor volume. The Distribution Lightning Arrester’s crimped structural construction ensures lightweight products with optimal mechanical strength. The manufacturing process ensures void-free construction and optimum interface sealing. This is achieved by bonding the silicone housing directly to the ZnO discs and aluminium end fittings using a special bonding solution.
The lightning arresters can be used to protect medium voltage distribution networks and equipment from switching and lightning lightning related over-voltages in areas with relatively high iso-keraunic levels. They are for both outdoor and indoor use to protect transformers and cable terminations.
