Product Description
The Glow Wire Test Apparatus is a high-precision testing system designed to evaluate the flame resistance and ignition behavior of electrical components, plastics, and insulating materials under simulated thermal overload conditions. This apparatus is widely used in electrical manufacturing, appliance testing laboratories, polymer industries, and standards certification environments.
The glow wire is constructed from nickel/chromium (80/20) alloy with a 4 mm diameter. It is capable of being heated up to 960°C, requiring a controlled current between 120 A and 150 A. The system ensures accurate and consistent heat delivery without affecting circuit stability.
During testing, the apparatus applies a precise force of 1.0 N ± 0.2 N to the specimen, with penetration strictly limited to 7 mm ± 0.5 mm, ensuring standard-compliant and repeatable results. A Class 1 thermocouple is used to measure tip temperature with excellent accuracy.
The spacious draught-free chamber (≥0.5 m³) prevents external airflow from affecting the results and allows clear observation of flame spread, ignition, or glowing behavior. The chamber design ensures that any burning or molten particles fall safely on the specified layer as per relevant IS/IEC standard.
Built with high-quality components, rugged construction, and advanced safety features, the Glow Wire Test Apparatus delivers reliable, repeatable, and industry-standard flame resistance testing, making it an essential tool for quality control and compliance certification.
