一、產(chǎn)品特點(diǎn)及用途 

1、 Product features and uses

無鹵低煙阻燃電纜適用于交流額定電壓450/750V及以下控制、監(jiān)控回路及保護(hù)線路等場合，特別適用于核電站、地鐵、劇院等安全系數(shù)要求較高的場所。該產(chǎn)品克服了傳統(tǒng)阻燃控纜的缺點(diǎn)，極大的便利了救火和人員疏散工作，避免了鹵酸氣體對(duì)儀器和設(shè)備的腐蝕，成為傳統(tǒng)阻燃控制電纜的換代型產(chǎn)品，它主要要以下五個(gè)特點(diǎn)：Halogen-free low smoke flame-retardant cables are suitable for control, monitoring circuits, and protection circuits with rated AC voltage of 450/750V and below, especially for places with high safety requirements such as nuclear power plants, subways, and theaters. This product overcomes the shortcomings of traditional flame retardant control cables, greatly facilitates firefighting and personnel evacuation work, avoids the corrosion of instruments and equipment by halogen acid gases, and has become a replacement product of traditional flame retardant control cables. It mainly has the following fivecharacteristics:

1、電纜燃燒時(shí)鹵化氫氣體釋放量低；

2、電纜燃燒時(shí)發(fā)煙量少，透光率高；3、電纜線芯長期工作溫度可達(dá)90℃，延長了電纜使用壽命；

4、絕緣線芯采用數(shù)字編碼，便于安裝、調(diào)試、維修；

5、采用筒式放線，可生產(chǎn)長達(dá)3KM以上的整根電纜。

1. Low release of hydrogen halide gas during cable combustion;

2. When cables burn, they emit less smoke and have higher light transmittance;

3. The long-term working temperature of the cable core can reach 90 ℃, which extends

 the service life of the cable;

4. The insulated wire core adopts digital coding, which is convenient for installation, debugging, and maintenance;

5. By using cylindrical cable laying, it can produce a complete cable of over 3KM in length.
