介绍：

低烟无卤阻燃耐火电缆--低烟无卤阻燃电缆具有难以着火并具有阻止或蔓延的能力，而且，一旦着火，它具有无卤，低烟，无毒，无腐蚀等特性。适用于如高层建筑，宾馆，医院，地铁，核电站，隧道，发电厂，矿山，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、低烟无卤电缆的阻燃等级分为A、B、C、D四个等级。

2、 The flame retardant rating of low smoke halogen-free cables is divided into four levels: A, B, C, and D.

　　阻燃等级供火温度供火时间成束敷设电缆的非金属材料体积碳化高度自息时间

Flame retardant grade, fire supply temperature, fire supply time, bundling of non-metallic materials for cable laying, volume carbonization height, self curing time

　　A ≥815℃ 40min ≥7升/米 ≤2.5米 ≤1h

A ≥ 815 ℃ 40min ≥ 7 liters/meter ≤ 2.5 meters ≤ 1h

　　B ≥815℃ 40min ≥3.5升/米 ≤2.5米 ≤1h

B ≥ 815 ℃ 40min ≥ 3.5 liters/meter ≤ 2.5 meters ≤ 1h

　　C ≥815℃ 20min ≥1.5升/米 ≤2.5米 ≤1h

C ≥ 815 ℃ 20min ≥ 1.5 liters/meter ≤ 2.5 meters ≤ 1h

　　D ≥815℃ 20min ≥0.5升/米 ≤2.5米 ≤1h

D ≥ 815 ℃ 20min ≥ 0.5 liters/meter ≤ 2.5 meters ≤ 1h

　　（2）、低烟无卤电缆绝缘采用不含卤素的交联聚乙烯，护套采用了不含卤素的聚烯烃材

(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，所以组成电缆的所有材料都不含卤素。电缆燃烧时释放的烟雾量很少，它不会产生很浓的酸雾，有毒气体，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.

　　三、主要性能

3、 Main performance

　　1、低烟无卤阻燃型

1. Low smoke halogen-free flame retardant type

　　1）阻燃性能应能通过GB18380的成束电缆燃烧试验。试验后电缆烧焦或受影响部分达到的高度应不超过火焰作用点以上2.5m，或单根垂直燃烧试验。

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）卤酸气体释放量试验 19981用测量PH值和电导率来测定气体的酸度（1L水中PH≥4.3 电导率值应不超过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）烟密缆或光纤在特点条件下燃烧的烟密度测定（透光率的小值≥60%）

3) Measurement of smoke density of smoke dense cables or optical fibers burning under characteristic conditions (minimum value of transmittance ≥ 60%)

　　4）导体直流电阻符合GB/T3956的规定

4) The direct current resistance of the conductor complies with the provisions of GB/T3956

　　5）工频耐压试验：电力电缆应经受3500V，5min不击穿。控制电缆应经受3000V，5min不击穿。

5) Power frequency withstand voltage test: Power cables should withstand 3500V without breakdown for 5 minutes. The control cable should withstand 3000V without breakdown for 5 minutes.

　　6）应经受-15℃的低温卷绕试验或低温冲击试验，试验后试样表面应无目力可见裂纹。

6) The sample should undergo a low-temperature winding test or low-temperature impact test at -15 ℃, and after the test, there should be no visible cracks on the surface of the sample.
