Electrical Cable Control Heavy Copper Core Flexible Mineral Insulated Fire Resistant Electric Wire Cable


Heavy Cu conductor flexible mineral insulated cables(BBTRZ):
  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. Outer sheath:Using anti-aging and weather resistant materials and  having good anti-aging and mechanical performance.
  4. Suitable for indoor and outdoor laying, able to withstand mechanical external forces. Single core cable can not be laid in magnetic pipes. 

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.

Technical Parameters
  1. Rated voltage of flexible mineral insulated cable:BBTRZ and WTTEZ are suitable for applications where the voltage between the core and the sheath and between the cores does not exceed 1kv ac and dc.
  2. Finished test voltage of flexible mineral insulated cable:light load 2000V/1min,overload 2500V/1min.
  3. Insulation resistance: Insulation resistance ≥1000MΩ/km. When the cable length is 10m, the insulation resistance is 10×1010Ω/km.
  4. Long-term operating temperature of flexible mineral insulated cables:
The long-term working temperature of inorganic mineral insulated cable is 700C. The allowable operating temperature of mineral insulated cables is 1050C in places where no one is involved. In special high temperature occasions, the short-term operating temperature can be less than 2500C.they can continuously supply power for more than 3 hours at 950-10000C flame burning temperature.Short or non-short working temperature can reach 10830C.
       5.Bending radius:
The minimum bend radius of Flexible mineral insulated cables meet the requirements of the table below:
