When it was placed in the firing situation at the fire disaster frequent area, it can still keep working for some time at the fixed laying situation . structure(Enlarge) Using characteristics: 1:The fire resistant characteristics of the finished electric wire cable and its testing methods are met the stipulation of GB12666.6. That is :it can not be broken down under the buring flame with 950oC--1000oC or 750oC-800oC at rated voltage. The cable can working 90 minutes or more at the firing temperature of 800oC 2:The finished cables can continuous work without broken for 5 minutes by the 3.5kv voltage testing at 20oC 3:Except the above-mentioned characteristics, the other functions are similar to its corresponding common electronic wire cable. 4:The allowed long-term working temperature of the wire cable is 70oC, the surrounding temperature when laying the cable in the air is not less than 0oC. The allowed bending radius of the wire cable is showed below : (1):it should not less than 8 times than the outer diameter of the wire cable when the outer diameter of the wire cable less than 25mm, (2):it should not less than 12 times than the outer diameter of the wire cable when the outer diameter of the wire cable is 25mm and more.
