Mutually insulated between wire, and be often twisted into round a center, whole outside is surrounded by the cover layer of high-insulation, and cable has
Interior energising, the feature of external insulation, cable has power cable, controls cable, compensating cable, shielded cable, high-temperature cable, marine electric
Cable etc., they are all made up of sub-thread or stranded conductor and insulating barrier, are used for connecting circuit, electrical equipment etc., cable derivative/new
Product mainly requires the different and convenience of equipment because of application scenario, application and reduces the requirement of equipment cost etc., and uses
New material, special material or change product structure or improve technological requirement or be combined by the product of different cultivars and produce
Raw, in recent years, in power system fire incident in the world, cause power system power supply to interrupt due to ignition of cable
Ratio there is ascendant trend, therefore, for power plant, transformer station etc., there is a large amount of electrical equipment, use fire-retardant and fire safe type
Number cable, the most only effectively prevent fire spreading, and ensure the uninterrupted power supply in the important loop of cable, reduce whole
The potential safety hazard of power system, the flame-retarded technology of cable is by adding Halogen or the resistance of Halogen in the plastic jacket of cable
Combustion agent, to reach the purpose suppressing it to burn, but, plastic jacket can the most aging split under flame condition, and flame will be straight
Penetrate unguarded insulator, and then the insulator that ignites, so that the fire resistance of cable has not existed；And fire-resisting cable is to use
The structure that fire-resistant wrapping tape combines with plastic insulation takes the integrity of holding circuit, and the advantage of the cable maximum of this structure is ratio
Relatively soft, technique is easily manufactured, and cost is relatively low, but this cable fire temperature grade is limited by insulant performance rate,
And be easily subject to some rodents and destroy, water resistance is poor, and plastic insulation material easily ignites, and burning makes temperature increase
Adding, and then cause fire-resistant wrapping tape carbonization, cable fire ability lost efficacy.
