Working Principle
Install the tested cable sample on the stainless steel ladder and fix it with adjustable metal rings. Set target flame temperature, burning duration and test voltage/current on the touch screen. The system completes automatic ignition, precise gas mixing and constant temperature flame output.The 5-channel load system continuously supplies rated voltage and current to the cable during combustion. K-type thermocouples track real-time flame temperature; the system automatically alarms and cuts off gas & flame once cable short-circuit occurs. After preset burning time, the machine stops heating automatically. Operators judge whether the cable maintains circuit integrity to confirm its fire resistance grade.Application Scenarios
