Micc Mineral Insulated Cable Mi Cable Fire Rated Cable

Flame Retardant Fireproof Mineral Insulated Cable (BTLY):

Copper core aluminum sheathed flexible mineral insulated cable(BTLY):
1. Conductor:Stranded from multiple strands of copper wire and having good bending performance.
2. Insulation:Using high temperature resistant, non-combustible inorganic insulating materials.
3.  Metal outer sheath:Made of aluminum alloy.
4. Outer sheath:Adopting environmentally friendly, aging-resistant, weather-resistant, low-smoke, halogen-free sheathing material.
5. Suitable for indoor and outdoor laying, able to withstand mechanical external forces.

Selection method
1.Flexible mineral insulated cables with plastic sheaths shall be used in the following cases:
The cable is laid in an environment that is corrosive to the copper sheath.
The cable is buried directly or piped.
The cable is laid in a non-technical space of the building and has aesthetic requirements. Where there are fire protection requirements, a halogen-free and low-smoke plastic outer sheath should be used.
2.Specification selection
Determine the maximum operating temperature of the cable according to the laying environment of the cable, reasonably select the corresponding cable current, and determine the cable specifications.
2.1: Flexible mineral insulated cables have two types of current carrying capacity according to different cable temperature:
Current carrying capacity at 70°C
Current carrying capacity at 105°C
2.2:Choosing the cable current carrying capacity should be in line with  the normal working temperature 70⁰C under the following laying conditions :
Clearing lines along walls, brackets, roofs and bridges.
Co-routed with other types of cables in the same bridge, shaft, cable trench, cable tunnel.
Other places where the cable sheath is too hot and may cause personal injury or equipment damage.
2.3:The cable is laid separately in the bridge frame, the cable trench, and the place where the pipe is worn by the unmanned machine. The current carrying capacity can be selected according to the normal working temperature 105⁰C.
2.4:The specification of flexible mineral insulated cable should be reasonably determined according to the actual length of the line and the length of cable delivery.
3.Key points of design
3.1Copper sheath can be used as a grounding wire, so PE lines are generally not needed.
3.2 Replacing the busway with a large-section flexible mineral insulated cable can reduce engineering investment and increase line safety.
