Information

At present, the cable industry used to be flame retardant (FireRetardant), low smoke zero halogen (LowSmokeHalogenFree, LSOH) or low smoke and low halogen (LowSmokeFume, LSF), fire (FireResistant), cable has fireproof performance are collectively referred to as the fireproof cable.

Flame retardant cable (FlameRetardant)

The characteristics of flame retardant cable is delaying flame spread along the cable so that the fire will not expand. Because of its low cost, so it is widely used for fireproof cable cable varieties in. Whether it is a single cable or laying conditions, cable burning can control the spread of fire in a certain range, thus avoiding major disasters caused by cable fire burn, in order to improve fire safety level of cable line.

Low smoke halogen-free flame retardant cable (LSOH)

Characteristics of low smoke halogen-free cable is not only has excellent flame retardant properties, and low smoke halogen-free cable material does not contain halogen, corrosive and toxic when burning low, little smoke, thus reducing the human body, instrument and equipment damage, is conducive to the occurrence of fire in time rescue. Low smoke halogen-free flame retardant cable has excellent flame retardancy, corrosion resistance and low smoke density, but its mechanical and electrical properties than common cable slightly worse.

Low smoke and low halogen flame retardant cable (LSF)

Between the release amount and smoke concentration index between flame retardant cable hydrogen chloride, low smoke and low halogen flame retardant cable with low smoke halogen-free flame retardant cable. Low halogen (LowHalogen) cable materials will also contain halogen, but low content.

The cable is not only has the flame retardant properties, and the release of the burning smoke less, hydrogen chloride emissions lower. The low smoke and low halogen flame retardant cable with polyvinyl chloride (PVC) as substrate, adding to the efficient flame retardant, HCL absorber and smoke suppressant and processing. So this kind of flame retardant materials significantly improved the combustion performance of the flame retardant pvc.

Fire-resistant cable (FireResistant)

Fire resistant cable is in the normal operation of the flame burning condition can keep a certain time, integrity can be maintained line (CircuitIntergrity). The fireproof cable during the combustion of acid gas smoke less, fire resistant performance is greatly improved, especially in combustion, accompanied by sprinkler and mechanical shock vibration conditions, can still maintain a full run cable line.

Cable standard and grade fire

The main technical indicators cable relates to fire safety is smoke flame retardant CO2 cable, the density and the toxic gas. The United States fire standards more attention before the two questions, but Europe and the United States on the fire safety has a completely different point of view.
