Description

Novel elevator cable

Technical Field

The utility model relates to a cable manufacturing technical field especially relates to a novel elevator cable.

Background

At present, the known outdoor elevator cable is a common outdoor elevator cable, and an insulating layer is arranged outside a core conductor. The cable not only passes through current in the operation process, but also bears the self weight, certain tensile force and certain torsion. The existing outdoor elevator cable is low in strength, not wear-resistant, not resistant to weather, not resistant to deflection, not resistant to torsion, poor in bending reciprocating use performance, incapable of bearing 100 thousands of bending motions, and capable of influencing technical problems of installation, use and the like.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects that the existing elevator cable has poor tensile strength and torsion resistance and short service life in the prior art and providing a novel elevator cable.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the design is a novel elevator cable, including the conductor that a plurality of angles such as arrange, the crowded package in the conductor outside is equipped with the insulating layer, the insulating layer is modified rubber mixture structure, and is a plurality of the outside cladding of insulating layer is equipped with the filling layer, the outside of filling layer is equipped with woven shield, the crowded package in the outside of woven shield is equipped with the sheath, the sheath is modified butyronitrile combined material structure.

Preferably, the filling layer is an inorganic insulating material.

Preferably, the braided shield layer is a metal shield layer structure, and the braided shield layer has a characteristic that the conductor is not subjected to a traction force.

Preferably, the conductor is formed by finely twisting a plurality of strands of copper wires, and the plurality of conductors have at least one grounding wire.

The utility model provides a pair of novel elevator cable, beneficial effect lies in: the utility model adds the insulating layer, the filling layer, the braided shielding layer and the sheath structure outside the conductor in turn, and the insulating layer with the modified rubber mixture structure is adopted, so that the cable has the performances of flexibility, bending resistance, flame retardance, fatigue resistance, large insulation resistance and the like; through the design of the braided shielding layer, the cable can completely eliminate the possibility of internal and external interference in the use process, has better tensile capability and torsion resistance, adopts the sheath of the modified butyronitrile composite material structure, has the advantages of flexibility, bending resistance, flame retardance, wear resistance, oil resistance, ozone resistance, water resistance, ultraviolet resistance, flexibility maintenance at low temperature and the like, and prolongs the service life of the cable.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a novel elevator cable, includes a plurality of conductors 1 that arrange such as angle, and conductor 1 is the fine hank of stranded copper wire and makes, when guaranteeing electric properties such as conductor resistance requirement, makes it have good bending and ductility, and a plurality of conductors 1 have an earth connection at least, has promoted the security performance of using.

The extruded package in conductor 1 outside is equipped with insulating layer 2, and insulating layer 2 is modified rubber mixture structure, and the outside cladding of a plurality of insulating layers 2 is equipped with filling layer 3, and filling layer 3 is inorganic insulating material, like the mica material, has promoted the fire behavior of cable.

The outside of filling layer 3 is equipped with braided shield layer 4, and braided shield layer 4 is the metal shielding layer structure, and braided shield layer 4 has the characteristic that makes conductor 1 not receive traction force, makes the cable get rid of the possibility of internal and external interference completely in the use, has more tensile strength and antitorque ability, and the crowded package in the outside of braided shield layer 4 is equipped with sheath 5, and sheath 5 is modified butyronitrile composite structure.

The utility model adds the structure of the insulating layer 2, the filling layer 3, the braided shielding layer 4 and the sheath 5 outside the conductor 1 in sequence, and the insulating layer 2 with the modified rubber mixture structure is adopted, so that the cable has the performances of flexibility, bending resistance, flame retardance, fatigue resistance, large insulation resistance and the like; through the design of weaving shielding layer 4, make the cable get rid of totally in the use internally and the possibility of external interference, more possess tensile ability and antitorque ability to adopt modified butyronitrile combined material structure's sheath 5, make the cable more have flexible resistant bending, fire-retardant, wear-resisting, resistant oil, resistant ozone, waterproof, ultraviolet protection, keep compliance etc. under the low temperature, promoted the life of cable, the utility model discloses the elevator cable is suitable for and has high mechanical stress, especially has tensile and torsional stress's reel application scenario simultaneously, and its weight is lighter, the external diameter is littleer, more possesses tensile ability and antitorque ability, is fit for promoting.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
