Glow Wire Tester

　　Product Introduction

　　The hot wire test is the best testing method for electrical products, which replicates the situation of a fire occurring under actual conditions. In most cases, it is impossible due to practical circumstances. Therefore, simulating the actual impact of a fire as much as possible is the best method for product testing.

　　The hot wire test machine is mainly used for electronic and electrical components or parts that are subjected to excessive thermal stress under fault or overload conditions. The hot wire test simulates the thermal stress caused by heat sources or ignition sources such as hot components or overloaded resistors in a short period of time, and uses simulation technology to evaluate the fire hazard. The instrument is suitable for plastic and non-metallic insulation materials used in lighting equipment, low-voltage electrical appliances, electrical instruments, and other electrical and electronic products for household electrical components, such as switch casings, relay sockets, etc. Widely applicable in various production enterprises, quality inspection departments, universities, and research institutes.
