Heat-resistant spark chamber

If you cannot maintain sufficient distance when disconnecting a load break switch, an arc will form that does not extinguish and can become hazardous. This switching arc must be channeled and/or extinguished. In higher voltage ranges, it gets very hot, which is why a temperature-resistant material must be used for the arc chamber. AGK offers suitable insulating materials with the DuroBest ® and K-Therm ® AS material groups. Depending on the voltage and thus the strength of the resulting arc, scatter plates are used constructively within the extinguishing chamber. This segmentation divides the large arc into several weaker arcs. At the same time, it also distributes the thermal load. AGK has high-quality manufacturing, which allows for very smooth surfaces that do not cause noticeable resistance when the arc
