Cable: Identification of low-smoke halogen-free power cables
Low-smoke halogen-free power cables, also known as environmentally friendly cables, are mostly used in hospitals and places with strict environmental hygiene requirements. The identification of low-smoke halogen-free power cables mainly lies in the identification of insulation materials. Based on different materials, it can be determined whether it is easy to burn, and whether it is a flame-retardant wire - ZRBV or a flame-retardant power system cable - ZRYJV... According to whether the enterprise has combustion, the color of the flame is identified; whether it smokes, and how much smoke is produced to analyze and judge whether it is a low-smoke halogen-free power engineering cable - WDZ-YJV. If so, identify the color of the smoke, such as: whether the smoke is clear smoke or...
Low-smoke halogen-free power Cable Also known as environmentally friendly cables, low-smoke halogen-free cables are mostly used in hospitals and places with strict environmental hygiene requirements.
The identification of low-smoke halogen-free power cables mainly lies in the identification of insulating materials.
Based on different materials, it can be determined whether it is easy to burn and whether it is flame-retardant wire. -ZRBV or through a flame-retardant power system Cable -ZRYJV...According to whether the enterprise has combustion, identify the color of the flame; whether it smokes, and how much smoke is produced to analyze and judge whether it is a low-smoke halogen-free power engineering cable-WDZ-YJV. If so, identify the color of the smoke, such as: whether the smoke is clear smoke or smoke containing carbon ash; whether there is sol drop, if so, see if the sol system can continue to improve combustion; and what kind of smell is produced during social combustion, etc.
Polytetrafluoroethylene: softens and deforms when exposed to fire, wrinkles in a thin layer, contains a small amount of coke, has a slightly burnt smell, and is non-flammable.
PVC: green flame hood, softening white smoke and hydrochloric acid smell, self-extinguishing plastic; placed in water and sink.
PP: blue face mask, transparent molten combustion zone, with molten glue drops and kerosene smell; placed in water, floating.
General : Black smoke, dripping molten glue, no coke ash, smell of nitrogen oxide compound, ductility.
Nylon: blue hood, melting, burnt hair, self-extinguishing.
Odorless, thick white smoke, white and residual ash, self-extinguishing.
Low-smoke halogen-free power Cable Specific gravity method
Density comparison method, that is, using the density of water as a reference, placing the plastic material in water. If it sinks, the density of the plastic is greater than water; if it floats, it is less than water. This method can be used in conjunction with other methods.
The above two methods are simple tests for flame-retardant power cables, flame-retardant wires, low-smoke halogen-free power cables, and low-smoke halogen-free wires.
