Are you familiar with the classification of flame-retardant cables?
The structure of flame-retardant cable is based on the same structure as general cable. According to the different fireproof materials of the cable, flame-retardant cable can be divided into halogen flame-retardant and low-smoke flame-retardant.
Halogen-containing flame-retardant cable means that the raw material of the cable is all or part of the halogen-containing high-pressure polyethylene (polyvinyl chloride) fireproof material, which has good flame retardant properties. However, this cable also has defects, that is, when a fire occurs, it will cause a lot of smoke and halogen acid vapor, which will corrode the surrounding staff and others, and rescuers need to carry gas masks for rescue.
Low smoke flame retardant cable halogen-free means that all or part of the raw materials of the cable are high-density polyethylene (XLPE) fireproof materials without halogen elements. This material not only has excellent flame retardant properties, but also is not easy to produce a lot of smoke and halogen acid vapor when the cable catches fire. However, its reflectivity and conductivity are worse than ordinary cables. With the sustainable development trend of society, flame retardant cables have gradually changed from the past halogen bulb flame retardant to low smoke halogen-free flame retardant. This flame retardant cable not only has excellent electrical equipment characteristics, but also improves the shortcomings of the past flame retardant cables.
As consumers, when purchasing flame-retardant cables, we should not only choose appropriate cables for installation according to the characteristics of flame-retardant cables, but also pay attention to the following situations:
(1) Low-smoke halogen-free flame-retardant cables should be selected as much as possible according to multiple key areas or mass places.
(2) According to fire safety requirements, purchasing personnel should strictly purchase flame-retardant cables according to the fire protection level.
(3) Since the human eye cannot distinguish the appearance of flame-retardant cables, the types of flame-retardant A, flame-retardant B and flame-retardant C depend on the manufacturer's logo. Therefore, when choosing a cable manufacturer, it is best to choose a manufacturer with user reviews in the sales market.
