Abstract
A combined platform for testing fireproof materials for cables includes a main frame for providing operating space; an air circulation system including a fresh air supply unit for supplying fresh air into the operating space and an exhaust gas treatment unit for treating the gas in the operating space under set conditions; an open flame system for providing an open flame for testing cables; a water circulation system for supplying water at least to the exhaust gas treatment unit and the operating space; and a control system for collecting at least the temperature and gas concentration in the operating space, and performing process control based on the collected results. The actual working conditions of scenarios such as fire-resistant cable tunnels and fire-resistant cable trenches can be simulated, and multiple tests such as combustion performance test and physical and chemical performance test can be carried out under various working conditions.
