IEC 60332-1-2 Single Insulated Wire And Cable Vertical Combustion
Tester
Single Wire And Cable Vertical Combustion Tester Production introduction:
The single wire and cable vertical combustion tester is mainly used
to detect the flame retardant properties of the insulating
materials of wires and cables under abnormal working conditions
(such as overheating, overload or short circuit). The equipment
strictly simulates the flame spread of the cable when it is laid
vertically. It can accurately evaluate the speed of the flame
spreading along the longitudinal direction of the sample and
simultaneously observe the ignition effect of the molten dripping
during the combustion process. The combustion box door must be kept
open during the test (Note: The box door is designed only for
equipment protection and daily dust prevention. According to the
requirements of the standard test procedures, it must be opened
during the experiment to ensure air circulation and observation
field). This device complies with international general flame
retardant test standards and is widely used in the verification of
fire safety performance of power cables, communication cables and
optical fiber composite cables.
