Abstract
The invention discloses a low-smoke and halogen-free fireproof double-shielded cable resistant to high temperature. The low-smoke and halogen-free fireproof double-shielded cable resistant to high temperature comprises a main cable core, a wrapping layer, an inner shielding layer, a thermal insulation layer, an insulation layer, an outer shielding layer and a protective cover, and is characterized in that an insulation board is arranged in the center of the wrapping layer; the cross section of the insulation board is rectangular; the two long sides of the insulation board are tangent with the main cable core; the insulation board is made of polyurethane with ceramic fiber and paraffin added; a fireproof layer is wrapped between the outer shielding layer and the protective cover; three drainage wires and a grounding cable core are wrapped inside the fireproof layer; the protective cover is made of low-smoke and halogen-free materials with antioxidant and waterproof factice added. The cable is good in electrical conductivity, long in service life, resistant to high temperature, fireproof, resistant to oxidation and high in shielding performance, is mainly applied to the fields of computers, communications, power generation, chemical oil and the like, and has the significant energy saving function.
Description
Technical field
The invention belongs to field of cables, relate in particular to a kind of low smoke and zero halogen fire resistant screened cable.
Background technology
At present, along with the continuous increase of cable consumption, the quality of cable is also proposed to high requirement.Especially cable is in high temperature or disturbs in the environment such as strong, just the combination property of cable is had higher requirement.Such as general cable adopts single screen, the workplace that can not meet high interference is used.Once and for example cable fire will discharge a large amount of dense smoke, toxic gas, it is more difficult that rescue work becomes.As long as meet the requirements, just can meet the actual service condition of cable.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of fire resistant strong, shielding insulation performance is excellent and oil resistant is anti-oxidant, the low smoke and zero halogen fire resistant screened cable of environmental protection and energy saving.
The present invention takes following technical scheme to realize: a kind of low smoke and zero halogen fire resistant screened cable, it comprises master core, belting layer, internal shield, thermal insulation layer, insulating barrier, outer shielding layer and protective sleeve, it is characterized in that: described belting layer center is provided with an insulation board, described insulation board cross section is rectangle, two of described insulation board are long mutually circumscribed respectively at described master core, described insulation board material is to add ceramic fibre, the polyurethane of paraffin, between described outer shielding layer and described protective sleeve, wrap up fireprotection layer, three drainage threads of described fireprotection layer internal package, a ground connection core, described protective sleeve is to add antioxidant, the low smoke and zero halogen material of waterproofing unction.
Described fireprotection layer material is to add the organosilicon of sealing fire prevention latex, expanded perlite, ceramic fibre.
Described ground connection core is to hold the braiding of albronze silk by annealed wire to form.
The present invention has following beneficial effect in sum: good conductivity of the present invention, long service life, fire resistant, oil resistance anticorrosion erosion, be mainly used in the fields such as computer, communication, generating, chemical petroleum, anti-oxidant, shielding properties is strong, also possesses significant energy-conserving action simultaneously, cable can be carried out to directed distribute heat, reduce heat loss, improved the utilance of cable distribute heat, and then reduced the loss to electric energy.

Wherein: 1, master core; 2, belting layer; 3, insulation board; 4, internal shield; 5, ground connection core; 6, insulating barrier; 7, thermal insulation layer; 8, outer shielding layer; 9, fireprotection layer; 10, protective sleeve; 11, drainage thread.
Embodiment
As shown in Figure 1, a kind of low smoke and zero halogen fire resistant screened cable, it comprises master core 1, belting layer 2, internal shield 4, thermal insulation layer 7, insulating barrier 6, outer shielding layer 8 and protective sleeve 10, it is characterized in that: described belting layer 2 centers are provided with an insulation board 3, described insulation board 3 cross sections are rectangles, two of described insulation board 3 are long mutually circumscribed respectively at described master core 1, described insulation board 3 materials are to add ceramic fibre, the polyurethane of paraffin, between described outer shielding layer 8 and described protective sleeve 10, wrap up fireprotection layer 9, three drainage threads 11 of described fireprotection layer 9 internal package, a ground connection core 5, described protective sleeve 10 is to add antioxidant, the low smoke and zero halogen material of waterproofing unction.
Described fireprotection layer 9 materials are to add the organosilicon of sealing fire prevention latex, expanded perlite, ceramic fibre.
Described ground connection core 5 is to hold the braiding of albronze silk by annealed wire to form.
The permission bending radius of this cable is the outside diameter of cable 10 times; It is 105 ℃ that this cable allows operational environment maximum temperature; The shielding rejection coefficient of this cable is less than 0.7.
The above is embodiments of the invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
