低煙無鹵阻燃耐火電纜--低煙無鹵阻燃電纜具有難以著火并具有阻止或蔓延的能力，而且，一旦著火，它具有無鹵，低煙，無毒，無腐蝕等特性。適用于如高層建筑，賓館，醫(yī)院，地鐵，核電站，隧道，發(fā)電廠，礦山，石油，化工等。
Low smoke halogen-free flame-retardant and fire-resistant cables - Low smoke halogen-free flame-retardant cables have the ability to be difficult to ignite and have the ability to prevent or spread, and once ignited, they have characteristics such as halogen-free, low smoke, non-toxic, and non corrosive. Suitable for high-rise buildings, hotels, hospitals, subways, nuclear power plants, tunnels, power plants, mines, petroleum, chemical industries, etc.
二、低煙無鹵電纜的阻燃等級分為A、B、C、D四個等級。
2、 The flame retardant rating of low smoke halogen-free cables is divided into four levels: A, B, C, and D.

?。?）、低煙無鹵電纜絕緣采用不含鹵素的交聯(lián)聚乙烯，護套采用了不含鹵素的聚烯烴材
(2) The insulation of low smoke halogen-free cables is made of cross-linked polyethylene that does not contain halogens, and the sheath is made of polyolefin material that does not contain halogens
料，所以組成電纜的所有材料都不含鹵素。電纜燃燒時釋放的煙霧量很少，它不會產(chǎn)生很濃的酸霧，有毒氣體，毒性很小。
Therefore, all materials that make up the cable do not contain halogens. The amount of smoke released during cable combustion is minimal, and it does not produce a strong acid mist or toxic gases, with low toxicity.

1、 低煙無鹵阻燃型
1. Low smoke halogen-free flame retardant type
1） 阻燃性能應(yīng)能通過GB18380的成束電纜燃燒試驗。試驗后電纜燒焦或受影響部分達到的高度應(yīng)不超過火焰作用點以上2.5m，或單根垂直燃燒試驗。
1) The flame retardant performance should be able to pass the bundled cable combustion test of GB18380. The height reached by the burnt or affected part of the cable after the test should not exceed 2.5 meters above the flame point, or a single vertical combustion test should be conducted.
2） 鹵酸氣體釋放量試驗 19981用測量PH值和電導(dǎo)率來測定氣體的酸度（1L水中PH≥4.3 電導(dǎo)率值應(yīng)不超過10us/mm）
2) The release test of halogen acid gas in 19981 uses measuring pH value and conductivity to determine the acidity of gas (pH ≥ 4.3 in 1L water, conductivity value should not exceed 10us/mm)
3） 煙密 纜或光纖在特點條件下燃燒的煙密度測定（透光率的小值≥60%）
