TRANSMISSION LINE ARRESTERS
Statistical studies have shown that lightning is the main factor for more than 60% of automatic outages occurring on trans mission lines, thus creating many issues for power supply utilities and their equipment in high voltage substations. SIMCATEC offers surge arresters with high grade HTV silicone rubber in insulating housing, appropriate structural design and high gradient ZNO element without external gap as TRANSMISSION LINE APRESTERS installed in parallel with the insulator string. By using TLA it is possible not only to mitigate the guard wire and associated costs like increased weight of tower the volume of its foundation and loosed due to circulating current but also to provide the possibility of 100% protection of transmission lines against lightning without any measurement for reducing the foot resistance of towers
