Yuanky low voltage surge arresters provide protection for low-voltage overhead lines, consumer in-house supplies, distribution transformers and other systems. The gapless metal- oxide varistor incorporated in the surge arrester reliably imposes low-value limits on surges caused by atmospheric overvoltages and switching transients, thus protecting the insulation of the consumer-side networks and equipment. The varistor has a very short response time (typically <100 ns) and can safely handle high-current impulses up to 100 kA, 4/10 us. The arrester's nominal discharge current is 10 kA. The metal-oxide varistor is enclosed in a sturdy, weatherproof polymer housing. Numerous tests have confirmed the durability of the housing, even when exposed to extreme temperature fluctuations and contamination. The LV surge arresters are in compliance with requirements Class Il as defined by IEC 61643-1. They are designed for applications in which protection against direct contact is not necessary. Special insulated adapter modules are available for use in insulated overhead-line svstems and the low- voltage bushings of distribution transformers.
