The NG-A(BTLY) cable represents a type of insulated (flexible) mineral-insulated cable, and the letters in its name mean: G - insulation, N - fire resistance, A - 950-1000 ℃ B - Mineral insulated cable for wiring, T - Copper conductor, L - Aluminum metal sheath, Y - Polyvinyl chloride outer sheath.
NG-A(BTLY) cable is a flexible mineral-insulated cable that has been improved on the basis of BTTZ mineral-insulated cable. It uses aluminum tube sheathing instead of copper tube sheathing, which increases production efficiency and reduces costs while maintaining fireproof and explosion-proof properties. It has high fire resistance, flexible design, and excellent electrical performance, making it suitable for important facilities and locations such as high-rise buildings, urban rail transit, nuclear power plants, and petrochemical plants. This cable is able to pass the three tests of the BS6387 fire resistance standard, including at 950 ℃ With continuous power supply under flame for 180 minutes, no breakdown occurs at 950 degrees. ℃ No breakdown after 180 minutes under flame and 60 minutes of immersion in water, 950 ℃ Withstands 180 minutes of impact vibration under flame without breaking. In addition, it also has the advantages of being waterproof, rodent-proof, high mechanical strength, and corrosion-resistant.
