China's road heading machinery industry has become domestic high-end equipment manufacture and strategic emerging industries emphasis supports developing industry.
The cable that the large tunnels full advance coordinative composition of equipments such as shield machine, development machine uses is referred to as cable for shield machine,
Because its working environment is special, it is desirable that cable is with bending radius is small, can frequently move torsion, meet wear-resisting, oil resistant, softness, resisting
The features such as drawing, is anti-tear, low temperature resistant, voltage class is higher and higher.
Shield machine relied primarily on import with soft rubber cable in the past, has many cable producers at present and starts development & production,
But the problems such as it is flexible poor that there are cables, and voltage class is relatively low, failure is more.
Invention content
The invention discloses a kind of shield machine soft rubber cables, with bending radius is small, can frequently move torsion, satisfaction
Wear-resisting, oil resistant, softness, tension, it is anti-tear, low temperature resistant the features such as, substantially increase the service life of cable.
The present invention is achieved by the following technical solutions：
A kind of shield machine soft rubber cable, including oversheath, inner sheath, insulated electric conductor, the insulated electric conductor is by conductor
On successively environmental sealing layer and insulating layer form, it is tangent two-by-two between the insulated electric conductor, be enclosed on the outside of the insulated electric conductor
Aluminium strip armor, the aluminium strip armor interior insulation conductor surrounding are filled with inner sheath, on the aluminium strip armor from the inside to the outside
It is enclosed with nanosponges layer, silicon rubber heat-resisting layer and oversheath successively.
Preferably, the insulating layer uses crosslinked polyetylene insulated layer.
Preferably, the conductor is twisted by multiply tinned copper wire.
Preferably, the nanosponges layer is made of four quadrant cylinder structures.
Preferably, the inner sheath uses neoprene.
Preferably, the sealant is identical as the material of insulating layer, if the sealant is by contacting successively, circumference uniform distribution
Dry section is that fan-shaped strip structure forms, and strip structure surrounds circular tube shaped and forms.
Compared with prior art, the beneficial effects of the invention are as follows：
1, oversheath of the invention has excellent flexibility, corrosion resistance, photostability, electrical property and mechanical performance,
It has been obviously improved tensile strength, strengthens tearing toughness, improves the quality stability of refining glue production and processing；
2, silicon rubber heat-resisting layer of the invention has stable silica chemical constitution, can assign elastomer unique performance,
And with excellent high temperature resistant, the characteristic of chemical-resistance, mechanical electric performance, native Zona degree and translucence；
3, nanosponges layer of the invention makes the anti-flammability of cable entirety greatly improve, and prevents cable unexpected burning, causes
Immeasurable loss；
4, the inside and outside of aluminium strip armor of the present invention has excellent flexibility, and is provided enough for the bending of the deformation of cable
Buffering, protect the nuclear structure of cable；
5, of the invention inner sheath and oversheath are applied in combination, and have high anti-tear, high intensity, wear-resisting, oil resistant, softness, resistance to
The characteristics of low temperature, meet cable for shield machine Special use environment, service life is long；
6, sealant of the invention facilitates separation conductor and insulating layer, keeps the wire stripping of cable more convenient, successively cuts
Break off edge layer and the insulation strip of sealant, can effectively avoid caused by wire stripping to conductor cause damage and cable material it is a large amount of
Waste；
7, shield machine soft rubber cable of the invention meets shield machine in use to the requirement of electric wire, and
The cable is with bending radius is small, can frequently move torsion, meet the spies such as wear-resisting, oil resistant, softness, tension, anti-tear, low temperature resistant
Point substantially increases the service life of cable.
