1 .Fire-proof performance is excellent, fire-resistant grade can
not only meet the national standard GB/T 19216-21 A 950 C.90 min
(BS6387:2013 C 950 C. 3 h requirements), but also can withstand
water spraying and mechanical impact in combustion. 2 .Continuous
length, whether single core or multi-core cable, can meet the needs
of power supply length, the limit length can reach 2000m. 3 .The
cross-section of single-core cable is large, and the cross-section
of single-core cable can reach 1000 mm2, and that of multi-core
cable can reach 240 mm2. 4 .The overload capacity is large, the
cable not only has a large carrying capacity, but also has a large
overload capacity. According to the wiring requirements, the
surface temperature of the cable is usually less than 70 C. If the
wiring is not touched or contacted with flammable building
materials, the temperature of cable sheath can reach 105 C. and the
allowable working temperature of fire-proof cable can reach 250 C
when it is cut off. 5 .No electromagnetic interference, fire-proof
cables and signals, control cables are laid in the same shaft. When
the fire-proof cables are shielded by copper sheath, they will not
interfere with the information transmitted by signals and control
cables. 6 .The cost of flexible fire-proof cables is lower than
that of mineral insulated cables under the same conditions because
of its advanced fabrication technology and simple installation.
