Flexible Mineral Insulated Fireproof Cable

Scope of Application
Mineral insulated isolated fire-proof cable is suitable for trunk lines, fire-fighting lines, escape and rescue systems, such as emergency lighting, fire monitoring, alarm systems, elevator systems, smoke exhaust systems, and control lines. The cable can also be used in places where the cable loop is easily affected by fire spread or directly affected by fire, or other places.

Standards Implemented
This product complies with the standard Q/ygdl 006-2017 Mineral Insulated Isolated Fire-proof Cables with Rated Voltage of 0.6/1kV, and meets the requirements of BS 6387：2013 Fire Test Method for Cable Line Integrity Test under Flame Conditions and BS 8491：2008 Large Diameter Power Cables Used for Components of Smoke and Heat Control System and Other Fire Safety Systems in Active Service - Fire-proof Integrity Evaluation Method.

Usage Characteristics
1. The long-term working temperature of the cable is 90℃, and the highest temperature of the conductor is 250℃ case of short circuit (lasting for 5 seconds at most).
2. The ambient temperature during cable laying shall be no lower than 0℃;
3. Minimum bending radius during cable installation: the allowable bending radius of the cable shall not be less than 15 times of the outer diameter of the cable.
4. The rated voltage of cable U0/U (Um) is 0.6/1 (1.2) kV.
U0: the rated power frequency voltage between conductor and ground or metal shield for cable design;
U: the rated power frequency voltage between conductors for cable design;
Um: the maximum value of the "highest system voltage" that the equipment can withstand.

Routine Test
Routine test voltage of cable is 3.5kV, and it shall not break down in 5min.

Cable Model and Name
Cable Model and Name: NG-A (BTLY) isolated flexible mineral insulated fireproof cable.
