New Baofeng low smoke and halogen-free cables can also be referred to as environmentally friendly cables. Low smoke and halogen-free electrical cables are mostly used in hospitals and places with strict environmental hygiene requirements.
Xinbaofeng low-smoke halogen-free cables can also be called environmentally friendly cables. Low-smoke halogen-free cables are mostly used in hospitals and places with strict environmental hygiene requirements.
The identification of Xinbaofeng low-smoke halogen-free power cables mainly depends on the identification of insulating materials.
According to whether different materials are easy to burn, determine whether it is a flame-retardant wire-ZRBV or a flame-retardant power system cable-zryjv... According to whether the enterprise is burning, distinguish the color of the flame; analyze and determine whether it is a low-smoke halogen-free power generation project cable-WDZ -YJV, if so, distinguish the color of the smoke, such as: whether the smoke is clear smoke or smoke containing carbon ash; whether there is sol dripping, if so, see whether the sol system can continue to improve combustion; and what kind of smell It is produced and developed when society burns.
Teflon: softens and deforms when exposed to fire, is thin, contains a small amount of coke, has a slight burnt smell, and is non-flammable.
PVC: green flame cover, softens the smell of white smoke and hydrochloric acid, self-extinguishing plastic; put in water and sink.
PP: Blue mask, transparent melting and burning area, melt glue dripping, smell of kerosene; put it in water to float.
Pu: black smoke, glue dripping, no burnt ash, odorous nitrogen oxides, ductility.
Nylon: blue mask, melts, perms, self-extinguishing.
Odorless, thick white smoke, white residue, self-extinguishing.
Low smoke halogen-free cable specific gravity method
Density comparison method, that is, placing plastic materials in water according to the density of water. If they sink, the density of plastic is greater than that of water, and if they float, it's less dense than water. This method can be combined with other methods
For the above two types, simply test flame-retardant powder cables, flame-retardant wires, low-smoke halogen-free cables, and low-smoke halogen-free wires.
