Wire and cable smoke density tester

Wire and cable smoke density tester

Product Introduction:

The wire and cable smoke density tester complies with GB/T17651.1-1998 and IEC61034-1-2:1997 "Measurement of smoke density of cables and optical cables under specific conditions of combustion". It is a testing device used to measure the transmittance of smoke emitted by all insulated metal conductor cables or optical cables used for transmitting electrical energy or signals when burned horizontally under specific conditions. (IEC61034 requires a smoke box size of 3m).

Applicable scope:

The national cable industry is vigorously developing low smoke and halogen-free cables and materials, which require measuring the smoke density of cables; The main principle of smoke density measurement is that in a specific space, cables or materials generate smoke under specific combustion or radiation conditions, and the beam of light will attenuate after passing through the smoke. The transmittance of the beam of light is measured and the specific optical density and smoke density are calculated. This tester can test the combustion smoke characteristics of cables or optical cables and provide reference for cable requirements in rescue facilities.
