交联聚烯绝缘固定敷设用电缆(电缆)含阻燃型、耐火型/无卤低烟阻燃型
一、产品特点及用途
交联烯烃绝缘电缆（电线〗有优异的机械物理性能和电气性能，适用于交流额定电压UO/U为450/75OV及以下动力装置、日 用电器、仪表及电信设备敷设用。
阻燃型电线电缆的主要特点是电缆不易着火或着火时延燃仅局限在一定范围龋适用于对阻燃性能要求较高的场合。
耐火型电线电缆的主要特点是电缆除了能在正常工作条件下传输电力外，电缆在着火燃烧时仍保持一定时间的正常运行，适用 于对耐火特性有要求的场合
低烟无卤阻燃型电线电缆的特点是电缆不仅备阻燃性能，而且有低发烟性和无害性（毒性和腐蚀性较小适用于对电缆 阻燃、烟密度、毒性指数等有特别要求的场合，如核电站、地铁等。

Characteristics and Application of the products ■
Cross-linking polyolefins in sulated cable (wire) has the advantages of excellent mechanical and properties.excellent eleclrical properties.it is used in suche places as electrical appliance.instrument and telecom device with A,C.rated voltage Uq/U up to and including 450/750V.
The main features of the flame retardant cable is hard to get fire or that the comtinuous buming of cables is very limited when it is on fire.it.applies to the "places with special demands of flame retadant property.
Fire-resistance of cable can operate normally for some time when it is buring except that it can transmit electrical power under normal condition.it is used in the places necessary to resist fire.
The main characteristics of low smoke, halogen-free,flame retardant cable &. wire is very tow smoke,ernission and harmless(low toxic.low corrosive)besides the property of flame retardant.it can be used in the places with special demands of property of flame retadan,the density of smoke emission and toxic index when cable gets burning,such as subway,turinel,nuclear power station.
Standards of the products
The cable is manufactured in accordance with our enterprise standard.
It can also be produced according to special requirements put forward by clients.
The flame retadant property of the flame retardant cable must meet the corresponding demands of class A.B.CWhich is stipulated in GB/T 19666-2005.Amongst the 3 class,class A is best C worst.Clients can select any typerof cable as practical needs.
Fire-resistance properyt of the flame -retadant eable can be classified as class A(950°C-1000°C/90min)and class B(750°C-800°C/9Qmin I |ln accordance with the standard of GB19666-2005 clients can choose any type cable as pracical needs.
The flame retardant properyt of m/ smoke,halogen-free,retardant cable must meet the corresponding ruquirements of class A.BorC which is stipulated in GB/T19666-2005.lt must pass the test of smoke density descrbed in GB/T17651 -1998,and the test measuring the pH vaule and conductivity which is stipulated in GB/T 17650.2-1998.
