Introduction
Glow-wire tester according to the standard GB4706.1 and GB/T5169.4. Glow-wire tester Time and temperature figures show, it is stable and reliable.
Product Details
1.Overviews
When the electrical components or the parts in the condition of failure or overload, the temperature may reach too high or ignited its nearby parts. Glow-wire test simulate hot components or the heat of the overload resistance or the ignition sources in such a short period of time caused by thermal stress, using the simulation technology to assess fire risk. Glow-wire test apply to electrical and electronic products, plastic which is used by the household electrical appliances and non-metallic components of insulating material components, such as: The shell of the switch and Relay socket.
 
2. Characteristics
(1). Glow-wire tester adopts integrated design of some part of test chamber and part of control, to facilitate the installation at the scene and debug. The shell of the test chamber and important components are adopted by stainless steel manufacturers, resistant cigarettes and gas corrosion; use the SCR automatic control system to adjust the current automatically, to achieve the purpose of precise temperature control; Time and temperature figures show, so that the observation and records are facilitate and the use of it is stable and reliable.

(2) Power Supply:Other power specifications can be customized

1.The temperature of incandescent wire could range from 500℃ to 1000℃, with a temperature tolerance for error of ±10℃ between 500℃ and 750℃, and ±15℃ between 750 and 1000℃. The accuracy of temperature measurement instrument is± 0.5 class. The thermocouple for measuring the temperature is armored with the nickel-chromium (K) wire of 0.5-0.55mm.
2.The incandescent wire imposed on the samples the power of 0.8N to 1.2N, and the restrict indentation depth is at least 7 mm.
3.The time of activation (Ta) on the specimen by the incandescent wire ranges from 0 to 99 minutes and 99 seconds. Normally, according to the standard requirements, set the time to 30 seconds, and a timer will be employed to count the time of ignition(Ti) and the time of extinguishments, with the time error of ±1S.
4、The operation of the equipment is simple, the temperature measurement system is reliable and has automatic temperature compensation function.
