Glow Wire Test Apparatus China Manufacturer
Glow Wire Tester uses simulation technology to evaluate the fire hazard of thermal stress caused by heat sources such as glowing components or overload resistance in a short time.
Plastic insulation materials or other solid combustible materials that are easy to spread flames inside the equipment may ignite due to the glow wire or hot components. Under certain conditions, such as fault current flowing through the wire, component overload, and poor contact, some components will reach a certain temperature and cause nearby parts to ignite. In the product development stage, people need a means to understand in advance the reliability of certain materials applied to specific locations and determine the specific hazards when burning occurs. This glow wire test chamber was born to help solve these problems. It is suitable for electronic equipment and its components and parts, as well as solid electrical insulating materials or other solid combustible materials such as plastics and rubber.
Test Principle
A standard glow wire loop in the test chamber is heated to a specified temperature. A sample mounted into the movable carriage moves along the guide rails at a prescribed speed toward the glow wire until vertically touching the tip of it. Under the pulling force of the two weights, the sample exerts a fixed lateral force against the glow wire tip and limits the depth of penetration of the specimen surface to at least 7 mm. During the test, test temperature, ignition time, flame extinction time and glow wire time can be measured one by one.
