Low-smoke halogen-free cable is a very environmentally friendly cable. It has the advantages of good smoke when burning, no corrosive gas escape, and long life. It is widely used in many fields. In use, low-smoke and halogen-free cables are often represented by WDZN, where W: means halogen-free and D: means low-smoke. z : Flame retardant n : Fire-resistant Just like the WDZN-BYJ cable we often use, WDZN-YJY cable is the cable we often use. So, in the specification, under what circumstances are low-smoke halogen-free cables used? Wire and cable manufacturer-Beijing Xinbaofeng.
1. JGJ242-2011 "Residential Electrical" stipulates that the cables clearly recorded in high-rise residential buildings should be flame-retardant cables with low smoke and low toxicity.
In high-rise residential buildings with more than 19 floors, the emergency lighting of public escape passages must use low-smoke, halogen-free and flame-retardant cables. In high-rise residential buildings with 10 to 18 floors, it is best to use low-smoke, halogen-free and flame-retardant cables for emergency lighting of public escape passages.
In densely populated environments such as underground passengers and commercial facilities, circuits that require enhanced fire safety are best to choose flame-retardant cables with low smoke and low toxicity.
When the distribution circuits of other important industrial and public facilities need to enhance fire safety, they can also choose flame-retardant or low-smoke, low-toxicity flame-retardant cables.
2. For buildings with high fire protection requirements such as JGJ16-2008 "Civil Regulations" category high-rise buildings and important public places, flame-retardant low-smoke halogen-free cross-linked polyethylene insulated cables and wires or smoke-free and halogen-free must be used Power cables, wires.
3. JGJ354-2014 "Sports Stadium": The conductor insulation type of sports buildings must be selected according to the laying method and environmental conditions, and comply with the following regulations: Special-grade and Class-A sports buildings, or Class A low-smoke and low-smoke for extra-large sports venues Poison B-level and C-level sports
Summary: Low-smoke halogen-free cables are used in:
(1) High-rise buildings and important public places
(2) Exposed cables in high-rise residential buildings
(3) Large and medium-sized department stores
(4) Large and medium-sized sports venues
(5) Museum
(6) Large transportation buildings (airport station)
The domestic applications of low-smoke halogen-free cable products are mainly concentrated in large-scale projects and high-tech fields. Such as railways, subways, cars, etc. When my country is building its railway network, low-smoke and halogen-free products are used for traction cables, signal cables, control cables, etc. to ensure the safety of passengers. Newly built subway projects in various places are no exception, using low-smoke and halogen-free products. In the automotive field, the importance of low-smoke and halogen-free products is gradually recognized, and most wiring uses low-smoke and halogen-free cables. In daily life, low-smoke halogen-free cables are widely used in nuclear power plants, subway stations, telephone exchanges and computer control centers, high-rise buildings, hotels, radio stations, important military facilities, oil platforms and other places with concentrated personnel and low air density.
The above is an analysis of the use of low-smoke and halogen-free cables. When purchasing cables, purchase wire and cable products as needed on the basis of meeting national requirements.
