Abstract
The utility model relates to a low-smoke, non-halogen and flame-retardant elevator cable, which belongs to the technical field of a cable of H01B class. A stranded conductor is arranged in the low-smoke, non-halogen and flame-retardant elevator cable, and the outside of the utility model is provided with an extruding sheath layer. The utility model is characterized in that the stranded conductor is provided with a low-smoke, non-halogen and flame-retardant insulation layer, a wire core is extruded and packed with a non-halogen and flame-retardant inner lining layer, and a circular low-smoke, non-halogen and flame-retardant sheath layer is extruded on the outside of the wire core. The utility model has the advantages of compact and round cable structure, small bending radius, easy installation, and low smoke, no halogen and flame retardancy of the utility model, high temperature-resistant grade, favorable anti-interference ability, etc.
Description
Technical field
The utility model belongs to H01B class cable technology field, particularly relates to a kind of low-smoke non-halogen flame-retardant elevator cable.
Background technology
Present known elevator cable, adopt Halogen material such as PVC insulating barrier, restrictive coating, its structure is not tight, in case breaking out of fire, the BLV cable fire can produce a large amount of dense smokes, make rescue work be difficult to carry out, personnel are scorched to death immediately, but suffocate owing to being smoked by smog, discharge the hydracid corrosive gas during material (PVC cable) of Halogen burning simultaneously, except harmful to human, also can cause the equipment consequential damages, the personnel that are not suitable for use than narrow and small place and the high-grade elevator of comparatively dense or space.
Summary of the invention
The utility model provides a kind of low-smoke non-halogen flame-retardant elevator cable for solving the problem that existing known technology exists.
The purpose of this utility model provide a kind of construction of cable closely, rounding, crooked half through little, have the elevator cable low-smoke non-halogen flame-retardant characteristic, that security reliability is higher.
This cable is to be the supporting private cable with low-smoke non-halogen flame-retardant performance of elevator staircase.Cable adopts soft conductor structure and low-smoke non-halogen flame-retardant elastomeric material, make Cable Bending Radius little, be easy to wiring and install.
The preferred insulating material of this cable adopts irradiation technique, makes the cable temperature resistant grade rise to 90 ℃, and anti-overload ability is 250 ℃ in short-term.
This cable extrudes the Halogen inner covering, makes the construction of cable tight, rounding.
This cable adopts low-smoke halogen-free flame-retardant isolating, inner covering, sheath design, has good low-smoke non-halogen flame-retardant characteristic, smoke density (light transmittance) 〉=60%, conductivity≤10 μ s/mm, PH 〉=4.3.
This cable adopts tin-coated copper conductor braiding external shield, has good interference free performance.
The utility model adopts following technical scheme:
The low-smoke non-halogen flame-retardant elevator cable, in stranded conductor is arranged, restrictive coating is extruded in the outside, is characterized in that stranded conductor has the low-smoke halogen-free flame-retardant isolating layer, core extrudes the halogen-free flameproof inner covering, round low-smoke halogen-free flame-retardant sheath layer is extruded in the outside.
The utility model can also be taked following technical measures:
Described low-smoke non-halogen flame-retardant elevator cable is characterized in that there is tin-coated copper conductor woven shield in the round low-smoke halogen-free flame-retardant sheath layer outside of extruding.
Described low-smoke non-halogen flame-retardant elevator cable is characterized in that stranded conductor closes conductor structure for the soft copper skein silk.
Described low-smoke non-halogen flame-retardant elevator cable is characterized in that insulating barrier, inner covering, restrictive coating are the low-smoke non-halogen flame-retardant layer of elastomer material.
Description of drawings
Fig. 1 is the utility model cross section structure schematic diagram.
Wherein, the stranded soft copper silk of 1-conductor, 2-low smoke and zero halogen insulating barrier, 3-low smoke and zero halogen inner covering, 4-low smoke and zero halogen restrictive coating, 5-screen.
Advantage that the utlity model has and good effect:
This cable is to be the supporting private cable of elevator staircase, owing to adopted the utility model scheme, therefore has following characteristics:
1. the construction of cable is tight, rounding.
Cable Bending Radius little, be easy to install.
3. cable low-smoke non-halogen flame-retardant.
4. cable temperature resistant grade height, anti-overload ability is strong.
5. has good interference free performance.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following example now, and conjunction with figs. is described in detail as follows:
Embodiment
With reference to accompanying drawing 1.
The low-smoke non-halogen flame-retardant elevator cable, in stranded conductor 1 is arranged, the soft copper skein silk closes conductor 1 low-smoke halogen-free flame-retardant isolating layer 2, core extrudes halogen-free flameproof inner covering 3, extrude round low-smoke halogen-free flame-retardant sheath layer 4 outside the inner covering 3, there is tin-coated copper conductor woven shield 5 in round low-smoke halogen-free flame-retardant sheath layer 4 outside.
Insulating barrier 2, inner covering 3, restrictive coating 4 are the low-smoke non-halogen flame-retardant layer of elastomer material.
