Large Combustion Test Equipment For Wires And Cables（UL 1581）capable of simulating real fire conditions, such as high temperatures and open flames.The "combustion performance" of electrical wires and cables is a critical aspect of their safety and reliability in various applications. This performance refers to how well these materials resist ignition, spread of flames, and smoke generation when exposed to fire or high temperatures. Meeting stringent combustion performance requirements is essential to prevent fires, limit damage, and ensure the safety of people and property. Flame Retardancy: Flame retardancy is one of the most crucial aspects of combustion performance. Wires and cables should be designed to resist the initiation and spread of flames. This is typically achieved by using flame-retardant materials in the cable's construction. Common flame retardant additives include halogenated compounds and phosphorus-based compounds. However, there is a growing trend towards using halogen-free materials due to concerns about the toxicity of halogen gases when burned.Test equipment should accurately measure combustion time, flame spread speed and other indicatorsFlame Spread and Dripping: In some cases, it's not enough for cables to resist ignition; they must
