High Voltage Fireproof Building Power Cable

Cross linked polyethylene insulated fire-resistant cable   This fire-resistant power cable is a necessary specialized cable for fire and security engineering. Its core advantage is that it can still maintain normal power operation for a period of time in an open flame combustion environment, ensuring that emergency equipment is not powered off. The product strictly follows the domestic standard GB12666.6 and the international standard IEC331. The fire resistance test is divided into two levels: A and B. The A level can withstand high temperature flames of 950~1000 ℃, and the B level can withstand flames of 750~800 ℃. Both types of fire resistance levels can withstand a continuous 90 minute fire supply test, and the entire test can stably carry the rated voltage without breakdown or power failure. This cable is specially developed for fire safety scenarios, mainly used for power supply and control lines of emergency facilities such as fire equipment, emergency indicator lights, and esc…
