What is the important index to evaluate the burning performance of wire and cable?

The smoke density test of wires and cables is an important index to evaluate the burning performance of wires and cables, because it relates to the difficulty of personnel escape. According to the statistics of the fire department, most of the deaths in the fire are caused by the harmful gases produced in the fire, suffocated by the diffuse smoke or unable to escape because they can’t see the road, so the smoke density test of wires and cables is very important.

The 3 metre cube smoke density apparatus for wires and cables is developed according to IEC 61034, BS 6853 and GB/T17651.1~2 test standards. It is mainly used for testing the smoke density performance of wires and cables. During the test process, when smoke is generated, the optical transmittance is constantly changed by blocking the optical path, and then the minimum transmittance value and the test time to reach the minimum transmittance are obtained.

The equipment is made of stainless steel, and the inner wall is treated with Teflon dark color to resist corrosion and have a long service life. Equipped with touch screen computer, automatic printing speed is fast and user experience is strong. Equipped with observation window, users can observe at any time. Complete imported accessories, stable operation, ensuring safety and professional reliability.
