Refractory Power Line
APPLICATION
This series of cables is low-smoke, halogen-free, flame-retardant, and has passed CRCC certification and EN45545-2 fire test. The product has a smaller outer diameter, lighter weight and better flexibility. It is suitable for various signal transmission control wiring.This series of cables is low-smoke, halogen-free, flame-retardant, and has passed CRCC certification and EN45545-2 fire test.

REFERENCE STANDARD
1. GB/T12706-2008 cable with rated voltage of 1KV and below
2. GB/T19666-2008 General Rules for Flame Retardant and Fire Resistant Cables
3. EN50200-2015 Test method for fire resistance of unprotected small cables for emergency circuits
PRODUCT FEATURES
1. Voltage level: 300V 600V 1800V
2. Temperature resistance range: -40-90℃
3. Section square: 1.5-240mm2
4. Number of cable cores: 1-5 cores
5. Fire resistance time: 90min 120min, using ceramic silica gel insulation system, can withstand fire water spray for 15 minutes, the circuit still works continuously.
6. Bending radius: 5D for fixed laying; 6D for non-fixed laying (D refers to the outer diameter of the cable)
PRODUCT STRUCTURE
PRECAUTIONS:
1. Fire-resistant cable installation. The fire-resistant cable cannot be bent directly by 90° (the cable's fire-resistant layer will be stress cracked for a long time).
2. The terminals and connecting ends of all fire-resistant cables should be protected from moisture (the fire-resistant layer has moisture absorption, which will affect the electrical properties of the line).
3. The cross-section of the cable conductor should be 1 to 2 larger design cross-sections. It is not recommended to choose a small cross-section, such as 0.5mm² and below, which may fuse the conductor (for reference)
4. The power control cable with a diameter of less than 20mm should be used as far as possible for the outer diameter of the cable. If the cable is larger than 20mm, the burning time will be increased.
