Executive Standard          
As the enterprise is standard with reference to GB9330-88 standard
Working Conditions:          
1.Environment Temperature in installation & Min.Bending Radius;Preheating is unnecessary when ambient temperature remains no lower than 0℃.The installation remains freefrom restriction by drop.Min.bending radius of the cable is stipulated as follows:
 ①It should be no less than 6times that of cable diameter for the cable without armor;
 ②It should be no less than 12 times that of cable outer diameter for armored cable or that with shielding truture of copper tape.
 ③It should be no less than 10times that of cable outer diameter for soft cable with shielding structure.          
2.Working Temperature:The long-term working temperature of conductor is 90℃ ,and it should be no higher than 250℃ in time of short circuit which lasts no longer than 5 seconds.             
3.Insulation Resistance：Volume Resistance Rate ρ at Max.Rated Temperature:no lower than 1012Ω.cm;Insulation Resistance Constant Ki:no smaller than 36.7MΩ.cm.
