The utility model solves technical problem and adopted the following technical scheme that：

Removal cable, it includes center core and oversheath；

The center core is twisted by three groups of pair twist cores, has packed layer in the gap setting of three groups of pair twist cores, And interior belting layer is surrounded with outside pair twist core and packed layer and forms cable core, have one cable core periphery is along the circumferential direction arranged side by side Insulated wire cores are enclosed, the insulated wire cores are parallel with the axis direction of cable core, and filling, insulated wire cores are provided between insulated wire cores Outside be surrounded with outsourcing belt, the outermost layer of cable is extruded with oversheath.

The core of the center core is made up of two insulated wire pair twists, and each insulated wire includes conductor and insulating barrier, in institute State and the first belting layer is surrounded with outside core, and tinned copper wire winding shielding and the second bag are externally provided with first belting layer Belt, the outermost layer of center core are extruded with small sheath.

The conductor is twisted using the ultra-fine copper wire bundles of 0.10~0.13mm and formed.

The small sheath is extruded by dumb light polyurethane material to be formed.

The oversheath is extruded by dumb light polyurethane material and formed.

Compared with the prior art, the beneficial effects of the utility model are embodied in：

The conductor of cable conductor is formed using the ultra-fine copper wires of 0.10~0.13mm according to regular stranded mode bundle strand, using super The regular twisted flexibility and resistance to bend(ing) energy that can effectively improve cable of thin copper wire.The insulating materials of cable uses perfluoroethylene Propylene copolymer Insulation Material, it has the advantages of specific insulation is high, dielectric constant and dielectric loss angle are small, while improves cable High and low temperature resistance, the center core of cable core is by three groups of pair twist core twisted synthesizing cables and fills rounding and forms, center core knot The tensile property of cable greatly improved in structure, cable is frequently pulled for a long time, under bending mobile status, integrally-built steady Qualitative, pull resistance.The shielding mode of line pair is：Tinned wird winding shielding not only improves the shielding properties of cable, increases simultaneously The tensile strength of core so that core bending property is more preferable, more soft.The oversheath of cable uses new dumb light polyurethane material Material, the material have excellent electrical property, have good elasticity and compression resistant morphotropism；The Flame Retardancy can meet simultaneously V0 levels as defined in UL94 standards, ensure that the fire resistance of cable；The material, which belongs to polyether thermoplastic polyurethane, to be had well Anti-wear performance, hardness reaches 88A, anti-wear performance be General Purpose Rubber material it is octuple more than；Tensile strength >=30MPA, it is general 2 times of logical material；So that the tensile strength of this cable improves 50%；Its resist bending and it is twisted over 50,000,000 cables Indeformable, conductor is not broken.The counter-bending number of cable improves 200%~300%.
