High Temperature / Fire Resistant Cable (Copper Core, Insulated)
HighTemperature/Fire Resistant Cable (Copper Core, Insulated)
Application
This high temperature and fire resistant cable isused for checking signals under high temperature conditions with rated voltageup to 300/500V. It works predominantly as a transmission wire for control andprotect circuits in fire fighting systems and security systems.
ProductStandard
Our high temperature and fire resistant cable is manufactured according to theQ/R-TW6009-2004 standard. The fireproof capability is strictly examined by the GB12666.6-1990 test which is equivalent to the IEC331 test.
Operating Characteristics
1. Operatingtemperature: 200℃ for long-termoperation, 1000℃ for operatingperiod less than 90min.
2. Rated voltageU0/U: 300/500V
3. Minimum ambient temperature: -60℃ for fixed installation, 20℃ for non-fixed installation
4. Bend radius: no less than 10 times the cable outer diameter for non-armoredcable, no less than 12 times the cable outer diameter for armored cable.
