Description
Technical Field
The utility model belongs to the technical field of the cable, concretely relates to resistant oily cold-resistant elevator cable.
Background
Elevator cable is used for electric energy transmission and information transmission in the elevator, current elevator cable adopts various function line combination forms mostly, when in actual use, elevator cable inevitably can stretch and suffer the corruption of oil stain, traditional elevator cable tensile strength and corrosion resisting property are relatively poor, long-time work under cold environment simultaneously, the condition of fracture can be appeared on the cable surface, need good insulation between each line of elevator cable in addition, just can guarantee mutual noninterference each other, and traditional insulating layer is because cold resistance is relatively poor, the condition of fracture easily appears in the insulating layer of working for a long time, seriously influence insulating effect.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough of prior art and providing an elevator cable resistant oil, cold-resistant, tensile.
The technical scheme of the utility model as follows: the utility model provides an resistant oily cold-resistant elevator cable, includes a plurality of power cords and data line, power cord and data line all intertwine become the twist form, and the power cord includes power sinle silk and the first insulation layer of cladding on the power sinle silk, the data line is including the data sinle silk that sets gradually, cladding second insulating layer and the shielding layer of cladding on the second insulating layer on the data sinle silk, and the cladding has the sheath outside power cord and the data line, first insulation layer and second insulating layer adopt the modified PVC of cold-fast type or the modified NBR of cold-fast type, the sheath material is for gathering perfluor ethylene propylene.
Preferably, the power wire core is formed by winding 10-60 anaerobic copper wires, and the data wire is formed by winding 20-100 anaerobic copper wires.
Preferably, the shielding layer is a copper-plastic composite tape.
Preferably, a steel wire rope is arranged in the sheath.
The utility model has the advantages that:
(1) the power wire core and the data wire core are mutually wound into a twist shape, so that gaps among the wire cores are effectively reduced, the volume of the cable is reduced, and the cable has higher tensile strength;
(2) the first insulating layer and the second insulating layer are both made of cold-resistant modified PVC or cold-resistant modified NBR, so that the cable has excellent cold resistance, and the cable still has good insulating property in a low-temperature environment;
(3) the sheath adopts fluorinated ethylene propylene, has good corrosion resistance, can avoid oil stain corrosion, is low temperature resistant simultaneously, has avoided the condition that the fracture appears in long-time use under the low temperature environment.
