Arrester's scope ±✘of application

AC gapless metal oxide surg ≈§>e arresters are used to p₽ rotect the insulation of "×AC power transmission and transformatio∞φφn equipment from lightni← ↕×ng overvoltage and ov ‍♠ervoltage. Suitable for overvoltage prΩ¶•↕otection of transformers, transmissi§≈on lines, distribution boards, swit>≈"★ch cabinets, power met← ering boxes, vacuum switches, ∏↓♣shunt compensation capacitors, rota≤>"↑ry motors and semicon÷€₩£ductor devices.

Arrester characteristics λ₹and principles

AC gapless metal oxide sur&∞βge arresters have excellent nonl♠¥→inear volt-ampere cha≤‍ racteristics, good resp★‌™onse characteristics,↕ε∑¶ no freewheeling, large flow capa λ‌city, low residual voltage, ↕ strong overvoltage supp '✔≠ression ability, stain÷✘ resistance, anti-agi™¶α✔ng, free from altitude cons​→÷traints, Simple structure, no gap, ♥∞tight seal, long life and other charact↕∞eristics.

The arrester exhibits a high resφ<istance state under •φthe normal system operating ♥∏ voltage, and only the microampere lev¥≥£el current passes through. Unde★☆✘'r the effect of over-voltage and laβ ≤rge current, it exhibits low resistan±β¶ce, which limits the res♥©¶×idual voltage across the arrester
