Description
Technical field
The utility model relates to field of cable technology more particularly to a kind of low smoke halogen-free fire retardant fire resistant computers and instrument to believe
Number cable.
Background technique
If existing computer is used for a long time under rugged environment with instrument cable, performance is too single, safety
It can would become hard to guarantee.It is dry often to encounter receiving load such as suspension, electromagnetism in day-to-day operation for active computer and instrument cable
It disturbs, transmit signal ambiguity, influence normally to use because environmental change such as causes to be hardened at the factors, tensile capacity is not strong, holds
Easy fracture or deformation, flame-retardant performance are not good enough.
Utility model content
The utility model aim is exactly in order to make up the defect of prior art, to provide a kind of low smoke halogen-free fire retardant fire resistant calculating
Machine and instrument signal cable.
The utility model is achieved through the following technical solutions:
A kind of low smoke halogen-free fire retardant fire resistant computer and instrument signal cable, include core, the core includes
Conductor is coated with synthetic mica tape flame retardant coating or Ceramic silicon rubber composite band flame retardant coating on the outside of conductor, two is led
Crosslinked polyetylene insulated layer, polyester belt belting layer one, tinned copper wire woven separated-shielding layer are successively coated with after body pair twist on the outside
With round rubber frame, it is equipped with multiple arcs protrusion in round rubber frame outer wall, a core is put into intermediate, six cores and is put
In the periphery of intermediate core, bundle strand is successively coated with fire resistance fibre filled layer, polyester belt band in the outside of cable core at cable core again
Layer two, the total shielded layer of tinned copper wire and low-smoke halogen-free polyolefin oversheath.
The conductor uses tinned copper conductor.
The utility model has the advantages that: the utility model uses double-layer shielding structure, has good shielding properties；It is each
It is wrapped with polyester belt between line group, mutually insulated is shielded between line group, split screen can not be interfere with each other with independent grounding；Cable is in fire
In the case of, when the fire proofing materials such as insulation and sheath fail, flame retardant coating sinters one layer of insulation into and is attached in flame combustion
It on conductor, can be powered with last for short, maintain fire rescue or illuminating line power supply；Cable shield is excellent, low capacitor, and has
Explosion-proof performance can be applied in intrinsically safe circuit, and multiple protrusions are equipped on the outer wall of the round rubber frame, are made
Position between each core is not easy to change, and structure is more stable, and frame has the performance for the tension resistance for increasing cable, extends
Service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, a kind of low smoke halogen-free fire retardant fire resistant computer and instrument signal cable, include core, it is described
Core includes conductor 1, is coated with synthetic mica tape flame retardant coating or Ceramic silicon rubber composite band fire resisting in the outside of conductor 1
Layer 2, will successively be coated with crosslinked polyetylene insulated layer 3, polyester belt belting layer 1, tin-coated copper after two 1 pair twists of conductor on the outside
Silk woven separated-shielding layer 5 and round rubber frame 6 are equipped with multiple arcs protrusion 7 in 6 outer wall of round rubber frame, by a line
Core puts intermediate, six cores and is placed on the periphery of intermediate core bundle strand is successively coated with fire-retardant fibre in the outside of cable core at cable core again
Tie up filled layer 8, polyester belt belting layer 29, the total shielded layer 10 of tinned copper wire and low-smoke halogen-free polyolefin oversheath 11.
The conductor 1 uses tinned copper conductor.
Claims (2)
