Combustion-retardant Wire & Cable Serial Products Product Standard Enterprise standard. At the same time, apart from implementing IEC60332 or GB/T18380-2001 or the GA306-2007 the Public Safety Industrial Standard for combustion retardant characteristics, products also adopt state standard (GB) for non-combustion-resisting type equivalent to the products.

Property for Use 1. Rated voltage(U0/U, from 300/300V to 26/35kV according to different kinds of product series. 2. The max.work temperature of cable for a long period is: 70, 90 and 105. 3. For short circuit (5s), the max.work temperature of conductor does not exceed 160 for 70; 250 for 90. 4. The temperature for laying cable is not less than 0. 5. Cable bend radius implements corresponding non-combustion-retardant cable standard stipulation. 6. Combustion-retardant characteristics can be divided into categories A and C (category B is not recommended). a. ZC-type combustion-retardant cable is used in general combustion-retardant places requiring IEC60332-3C category. b. ZA-type combustion-retardant cable is used in combustion-retardant places requiring relatively harsh IEC60332-3A category. c. Single cable should reach the requirement of IEC60332-1(2) non- burning, that is, self-extinguishing nature. Multi-cable or a bundle of cable will only burn in a certain scope after reaching the IEC60332-3 standard and will extinguish itself.
