Abstract
The utility model relates to electric wire field, is specifically related to a kind of fire-resistant wires, and it comprises copper conductor and ceramic rubber insulation, and described copper conductor is arranged in ceramic rubber insulation, and described ceramic rubber insulation is Ceramic silicon rubber insulating barrier.The utility model ceramic rubber insulation fire resistance is good, and structure is simple, and performance is good, can meet melting, calendering, drawing, stranded/to press the requirements such as stranded.
Description
Technical field
The utility model relates to electric wire field, particularly a kind of fire-resistant wires.
Background technology
Electric wire in order to transmit electricity (magnetic) can, information and realize electromagnetic energy conversion wire product, the electric wire of broad sense is also referred to as cable, and the cable of narrow sense refers to insulated cable, and it may be defined as: the aggregate be made up of following part; One or more insulated wire cores, and their coating layers that may have separately, total protective layer and outer jacket, cable also can have the additional conductor not having to insulate.In order to transmit electricity (magnetic) energy, information and the wire product realizing electromagnetic energy conversion.
Fire-resisting cable also makes fire-resistant wires refer to the cable that can keep certain hour safe operation in flame combustion situation.The IEC331 such as China standard GB/T 12666.6() divide A, B two kinds of ranks fire resistance test, A level flame temperature 950 ~ 1000 DEG C, continue for fire time 90min, B level flame temperature 750 ~ 800 DEG C, continue for fire time 90 min, whole duration of test, sample should bear the load voltage value that product specifies.Fire-resisting cable is widely used in the place relevant with fire safety and fire-extinguishing and lifesaving such as skyscraper, underground railway, undergrond street, large-scale power station and important industrial and mining enterprises, such as, fire-fighting equipment and promptly to supply line and the control circuit of the emergency services such as leading lights.
Flame retardant cable, refers to that sample is burned under regulation experimental condition, after removing test burning things which may cause a fire disaster, flame spread only in limited range, residual flame or residual to burn in limiting time can the cables of self-extinguish.Basic characteristic is: be likely burned in case of fire and can not run, but can stop spreading of the intensity of a fire.Generally, electric wire, just in case catch fire, can be limited in subrange burning, not produce and spread, keep other various equipment, avoid resulting in greater loss.
Prior art situation, the defect of prior art or deficiency: existing electric wire adopts the manufacture of common material, a layer insulating is wrapped up outside wire, such cable outer field insulating barrier when breaking out of fire is easy to be burned, and then may get angry calamity, cause property loss, can not meet the demand of people in the today of the motorized day by day of living.
Utility model content
Goal of the invention of the present utility model is: for prior art Problems existing, provides a kind of fire-resistant wires.
To achieve these goals, the technical solution adopted in the utility model is: a kind of fire-resistant wires, comprise copper conductor and ceramic rubber insulation, described copper conductor is arranged in ceramic rubber insulation, and described ceramic rubber insulation is Ceramic silicon rubber insulating barrier.
