Lamco’s Gapless Metal Oxide Surge Arrester are meant for protection of high voltage equipment such as power or distribution transformers, circuit breakers , C.T / P.T’s etc., against over voltage of any kind. These arresters are manufactured to meet National & International standards, and can be generally applied for outdoor installation up to an altitude of 1000 mtrs.
LAMCO offers a complete range of surge arresters from distribution to high voltage applications comprising of solutions for AC up to 1200kV as well as special applications. LAMCO's portfolio includes porcelain housed, silicone housed insulated Low/Medium/High voltage arresters. LAMCO has 37 years of experience of porcelain arresters and more than 20 years of experience with silicone insulated arresters. The arresters are installed across the world in all types of climates. The designs are type tested according to the IEC 60099-4, and also comply with customer specific standards.
