IEC60331 Electric Cable Fire Resistance Testing Equipment -- Model CFRT

Introduction:

CFRT IEC60331 Electric Cable Fire Resistance Testing Equipment is used for testing cables required to maintain circuit integrity when subject to fire alone or fire with shock where the test condition is based upon flame with a controlled heat output corresponding to a temperature of at least 750˚C or fire with shock at a temperature of at least 830 °C.​

Reference Standards:

• IEC 60331 Test for electric cables under fir conditions Circuit integrity;
• IEC 60331 Part 11 Fire alone at a flame temperature of at least 750˚C;
• IEC 60331 Part 21 Cables of rated voltage up to and including 0.6/1kV;
• IEC 60331 Part 12 Fire with shock at a flame temperature of at least 830˚C;
• IEC 60331 Part 31 Fire with shock Cables of rated voltage up to and including 0.6/1kV;

Specifications:

Features:

• Heat Source : AGF Ribbon Type Propane Gas Burner
• Structured with 3 rows of cross holes, Average front width of burner: 15mm, Hole diameter: 1.32mm, Distance between the center: 3.2mm.
• A polished hole row in pilot hole for flame preservation in both faces of Burner plate.
• Two thermocouples are horizontally installed separated 45mm left and right of burner center-line to check temperature.
• Mass flow controllers to regulate the gas and air flow, the accuracy is not less than 1.5%.
• Software can show the burner calibration temperature, propane and air flow rate etc.
• The current is provided by a three-phase star transformer with sufficient capacity to maintain the required test voltage when circuit integrity cannot be maintained.
• Conductor connection indicator (LED indicator) to form a current.
• The voltage value is automatically set by software and adjusted by a panel controller.
• Digital display of the current and voltage data, accuracy of current is 0.001A.
• Current protection using fuse with 2A.
• The real-time measurement data of all current and voltage are collected by computer, and the curves of current and voltage are generated.
• When circuit integrity cannot be maintained, the corresponding indicator lamp is extinguished, the computer automatically determines the state and records the time, and sends out the sound and light alarm.
