Abstract
The utility model discloses a kind of elevator cable, comprise some conductors, some conductors are all coated with the elastic body insulated layer of TPE outward and form insulated wire cores, insulated wire cores is centered around center bedding core and forms cable core, center bedding core adopts the rear also coated insulation layer of aramid fiber tow strand, cable core is coated with outer cover, polyurethane external sheath layer, is provided with anti-twist layer in polyurethane external sheath layer, and anti-twist layer adopts copper wire and the braiding of high carbon fiber wire to form.The utility model structural design is simply compact, and insulation and sheath have all adopted the material with good cold tolerance energy, the elevator using at low temperature environment to meet those needs; Sheath adopts polyurethane, can meet cable and use the environment for-25 ℃ in working temperature; In addition, cable also has good warp resistance performance.
Description
technical field:
The utility model relates to electric wire, relates in particular to a kind of elevator cable.
background technology:
Conventional elevator cable, though be polyvinyl chloride insulation or rubber covered, its insulation and sheath material be all not possess good resistance to low temperature, cannot meet the use in those needs low temperature environments, in addition, the torsional resistance of elevator cable is comparatively weak.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of elevator cable, and structural design is novel, can improve resistance to low temperature, the torsional resistance of cable.
The technical solution of the utility model is as follows:
Elevator cable, comprise some conductors, it is characterized in that: some described conductors are all coated with the elastic body insulated layer of TPE outward and form insulated wire cores, insulated wire cores is centered around center bedding core and forms cable core, center bedding core adopts the rear also coated insulation layer of aramid fiber tow strand, cable core is coated with outer cover, polyurethane external sheath layer, is provided with anti-twist layer in polyurethane external sheath layer, and anti-twist layer adopts copper wire and the braiding of high carbon fiber wire to form.
Described elevator cable, is characterized in that: it is 5 class copper conductor or tinned copper conductors that some described conductors adopt conductor 1.
Described elevator cable, is characterized in that: described outer cover adopts the overlapping wrapped formation of polyester belt, and the wrapped rate of putting up is not less than 26%.
The utility model has the advantages that:
The utility model structural design is simply compact, and insulation and sheath have all adopted the material with good cold tolerance energy, the elevator using at low temperature environment to meet those needs; Sheath adopts polyurethane (TPU), can meet cable and use the environment for-25 ℃ in working temperature; In addition, cable also has good warp resistance performance.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to accompanying drawing:
Elevator cable, comprise some conductors 1, the some outer elastic body insulated layers 2 of TPE that are all coated with of conductor 1 form insulated wire cores, insulated wire cores is centered around center bedding core and forms cable core, center bedding core adopts the rear also coated insulation layer 4 of aramid fiber yarn 3 bundle strand, cable core is coated with outer cover 5, polyurethane external sheath layer 6, is provided with anti-twist layer 7 in polyurethane external sheath layer 6, and anti-twist layer 7 adopts copper wire and the braiding of high carbon fiber wire to form.
It is 5 class copper conductor or tinned copper conductors that some conductors 1 adopt conductor 1.
Outer cover 5 adopts the overlapping wrapped formation of polyester belt, and the wrapped rate of putting up is not less than 26%.
