How To Identify Low Smoke Halogen-free Power Cables？

The identification of low-smoke halogen-free power cables mainly depends on the identification of insulation materials

Determine whether the material is a flame-retardant wire ZR-BV or a flame-retardant power cable (xlpe ht cable, xlpe insulated 3 core 35mm2 copper electrical cable, xlpe insulated 250mm2 power cable) (ZR-YJV... depending on whether it burns easily) , identify the color of the flame; whether it emits smoke and the amount of smoke, determine whether it is a low-smoke halogen-free power cable WDZ-YJV (cable xlpe yjv, zr-yjv 5 core lapp cable, steel armored cable yjv32 5 core)

if so , identify the color of the smoke, such as: is the smoke clear smoke or smoke containing charcoal ash; whether there is sol dripping, and if so, see whether the sol continues to burn; and what kind of smell is produced when burning, etc.
