The utility model discloses make the cable performance promote, more soft, fire -resistant, heat -resisting, temperature resistant, fire -retardant, more anti mechanical shock, water -resistant spray, satisfy C, W, the requirement of Z type fire resistance testing of BS6387 regulation completely, and on -the -spot construction and installation is simple. Accord with the requirement of mineral insulation class noninflammability cable in the GB50016 architectural design fire prevention standard, can directly obviously apply, need not wear metal conduit and adopt the protection of closed metallic channel box.

Description

Flexible mineral insulation fire-resisting cable

Technical field

This utility model belongs to the technical field of cable, is related to flexible mineral insulation fire-resisting cable, it is adaptable to will to cable Ask relatively soft, have the occasion of particular/special requirement to fire resisting, heat-resisting, heatproof, fire-retardant etc., it is ensured that cable is steady in a long-term under thermal-flame Operation, resistance to mechanical impact, water resistant spray performance under thermal-flame, while meeting in cable shaft, ditch together with other cable runs The requirement laid.

Background technology

Along with the continuous development of social economy, the increasingly raising of living standards of the people, many skyscrapers, large-scale business Being continuously increased for field, subway, exhibition center and stadiums, also more payes attention to the fire prevention importance of important place.Particularly exist In the case of fire, ensure that electric power is unimpeded with communication, wins to greatest extent the rescue time of preciousness within a certain period of time, subtract The injures and deaths of few personnel and the loss of lives and properties.

Fire-resisting cable remains to keep the normal operation of certain hour in ignition, is mainly used under Fire Conditions Also must assure that normally transmit electric power or signal important events, have many fire-resisting cables, some production and processings in the market Complex process, installs also complex, and some fire protecting performances do not reach operation steadily in the long term, resistance to mechanical punching under thermal-flame Hit, water resistant sprays performance.So in the urgent need to a kind of fire resistance is superior on market, production, mounting process are simple, easy construction Fire-resisting cable.

Utility model content

Main purpose of the present utility model is to provide a kind of flexible mineral insulation fire-resisting cable, lifts cable performance, More soft, fire resisting, heat-resisting, heatproof, fire-retardant, the impact of more resistance to mechanical, water resistant spray.

In order to reach above-mentioned purpose, solution of the present utility model is：

Flexible mineral insulation fire-resisting cable, by conductor wire core, composite insulation layer, inserts, sheath, Halogen band and wrinkle Copper sheath is constituted；It is flexible mineral insulation Muscovitum that the composite insulation layer coated on conductor wire core is double-layer insulating structure, i.e. internal layer Band, outer layer is crosslinked polyetylene insulated layer；The conductor wire core of covered composite yarn insulating barrier is twisted and forms cable core together, in the middle of cable core Inserts are filled in gap, and cable core periphery cladding sheath, sheath adopts Ceramic silicon rubber band, wrapped Halogen on sheath Band, coats wrinkle copper sheath on Halogen band.

The conductor wire core is copper conductor.

The Halogen band is double-deck Halogen band.

The inserts are mineral wool rope.

After said structure, the insulation of this utility model conductor wire core adopts compound inslation, has both ensured the electrical resistance of cable Can, there is fire resistance again；Certain thickness Ceramic silicon rubber band sheath and wrinkle copper sheath, ceramics are increased outside cable core SiClx rubber strip sheath can rapidly be changed into duricrust tubular fire heat insulation structural when fire or high temperature is met, in fire fighting environment still Certain hour can be maintained to be not damaged by, at the same wrinkle copper sheath also have good fire resistance, so as to effectively stop flame or Damage of the high temperature to primary insulation.

This utility model is further illustrated with reference to the accompanying drawings and examples.

Description of the drawings

Fig. 1 is structural representation of the present utility model.

Label declaration

Conductor wire core 1, flexible mineral insulation mica tape 2, crosslinked polyetylene insulated layer 3, inserts 4, sheath 5, wrinkle Copper sheath 6, Halogen band 7.

Specific embodiment

As shown in figure 1, flexible mineral insulation fire-resisting cable of the present utility model, by conductor wire core 1, composite insulation layer, fills out Charge 4, sheath 5, Halogen band 7 and wrinkle copper sheath 6 are constituted.Conductor wire core 1 can adopt copper conductor.Coat on conductor wire core 1 Composite insulation layer, composite insulation layer is double-layer insulating structure, i.e., internal layer be flexible mineral insulation mica tape 2 it is wrapped in conductor wire On core 1, outer layer is coated on flexible mineral insulation mica tape 2 for crosslinked polyetylene insulated layer 3.Leading for composite insulation layer is coated Wire core 1 is twisted and formed together cable core.Gap filling inserts 4 in the middle of cable core, inserts 4 can adopt mineral wool rope, outside cable core Cladding sheath 5 is enclosed, sheath 5 adopts Ceramic silicon rubber band, wrapped Halogen band 7 on sheath 5, Halogen band 7 is double-deck nothing Halogen band.Wrinkle copper sheath 6 is coated on Halogen band 7.

Flexible mineral insulation fire-resisting cable described in the utility model, employs the fire proof construction of multilamellar, is that fire-resisting cable is produced The upgrading of product, that is, it is due electrically and mechanical performance to remain cable product, while improve the heat-resisting of cable product, heatproof, Fire resisting and the performance such as fire-retardant, fully meet C, W, Z-type fire resistance test requirement that BS6387 specifies, and in-site installation construction is simple.Symbol Close GB50016 Code for fire protection design of buildings Minerals to insulate the requirement of class noninflammability cable, can direct surface, it is not necessary to wear gold Belong to conduit and protected using closed metal groove box.
