Wire and cable bundle combustion tester

Wire and cable bundle combustion tester

Product Introduction:

The wire and cable bundle combustion tester is designed according to the requirements of UL1685 and GB18380.3 standards for wire and cable bundle combustion tests. And comply with IEC 60332-3-10, KS C IEC 60332-3-21-25 (Class A to D) standards. In addition, if the burner of this tester is adjusted by 20 degrees, it can meet the testing standards of IEEE 383 (IEEE 1202). The equipment can be equipped with a heat release instrument configuration port, which can be used in conjunction with a gas analysis device to measure thermal power values, such as H.R.R (heat release rate) and S P. R (smoke generation rate), etc.

Applicable scope:

The single vertical flammability tester for wires and cables is suitable for testing the flame retardant performance of the insulation layer of wires and cables under abnormal conditions such as overheating and overcurrent under flame conditions. It can be applied to the vertical flame spread test of wires, cables or optical cables, and can also verify the combustion status of droplets under flame conditions.
