Combustion Test Equipment is suitable for testing the flame retardant properties of the insulating layer of wires and cables under abnormal conditions such as overheating and overcurrent.suitable for UL1581, UL13, UL444, UL1655 VW-1 and FT-1, FT-2 of CSA.
ZONSKY The Large Combustion Test Equipment for Wires and Cables is a specialized testing device designed to evaluate the fire performance and combustion characteristics of wire and cable assemblies under controlled conditions. This apparatus subjects samples to standardized flame exposure, measuring critical parameters such as ignition time, flame spread rate, heat release rate, and smoke production.
It is composed of test part and control part and adopts integrated design, which is convenient for on-site installation and debugging. The control system has a high degree of automation and has an automatic ignition function. Real-time display of temperature and time, easy to observe and record, stable and reliable use.
The back of the box is equipped with a strong exhaust and smoke exhaust system. After the test is completed, it is opened at the same time as the air supply system, which can discharge the exhaust gas to the outside in time. The front of the box is provided with a sealed tempered glass window and an operation window, which is convenient to observe the test process and facilitate the operation of the experimenter.
Compliance: UL1581-2006 Section 1060 (Vertical Burning and FT1 Test), Section 1061 (Cable Burning Test), Section 1080 (VW-1 Burning Test), and Section 1100 (Horizontal Specimen/FT2 Burning Test Requirements.
1.Instrument composition: It consists of two parts: combustion box and control part.
2. Test box: the volume is greater than 4m³. The area above the test flame is larger than 2.0m³; the inside of the box is composed of a frame, covered with a 1.2mm thick electrostatic high-temperature paint steel plate, processed by CNC machine tools, and the outside is sprayed with plastic. The second layer is made of black matte paint, which has the characteristics of anti-rust and anti-corrosion.
3. There is a ventilation and smoke exhaust system on the back of the box, and forced exhaust is used. The exhaust gas can be discharged outdoors after the test is completed.
4. Operating equipment: There is an operating window under the observation window, with a length of about 600mm corrosion-resistant long-arm gloves, which is convenient for sealing operation.

12. Dimensions of the equipment: L1800mm*W1120mm*H2100mm (excluding the size of the exhaust port and casters)
1.Heat conductors (copper conduits and thermocouples)—the conduit structure should be electrolytic copper with extremely high conductivity. The electrolytic copper weight was 10 g.
2. Armored K-type thermocouple, with 0.5mm diameter stainless steel tube as jacket.
3. The hand-held temperature control meter matches the K-type thermocouple. Its reading can be greater than 1000 ℃. After the temperature is measured, it can be removed from the box, which has the characteristics of intuitive and convenient counting, and improves the service life of the thermocouple. )
The test bracket is assembled from high-quality SUS304 stainless steel + bakelite, which has the characteristics of rust resistance and corrosion resistance.
