This high temperature and fire resistant cable is used for checking signals under high temperature conditions with rated voltage up to 300/500V. It works predominantly as a transmission wire for control and protect circuits in fire fighting systems and security systems.
Our high temperature and fire resistant cable is manufactured according to the Q/R-TW6009-2004 standard. The fireproof capability is strictly examined by the GB12666.6-1990 test which is equivalent to the IEC331 test.
1. Operating temperature: 200℃ for long-term operation, 1000℃ for operating period less than 90min.
