Description

A kind of high intensity armouring insulated cable

Technical field

The utility model belongs to field of cable technology, and in particular to a kind of high intensity armouring insulated cable.

Background technique

Armored cable is mounted in the sheath for having insulating materials by the conductor of different materials, is able to be processed to bear mechanical The high-strength cable of external force, armored cable can be directly buried or be installed in the shaft.Armored cable be mainly used for chemical industry, metallurgy, The field of machine-building, power generation and scientific experimentation etc..

Often there is the insufficient defect of intensity in existing armored cable, long-time service will cause cable failure, and there are safety Hidden danger, while armored cable price is higher, service life is short to will cause biggish economic loss.

Utility model content

The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of high-intensitive armouring insulated electro Cable.

A kind of high intensity armouring insulated cable, including core wire, armor, polyolefin jacket, it is characterised in that: the core wire Quantity be four groups, the core wire is uniformly arranged in most inner side, core wire by set gradually from inside to outside twisted wire, inner insulating layer, Pe sheath composition, the twisted wire are constituted by the tensile cord of copper wire and at least one is twisted, and the setting of core wire is in the first glass In cloth wrapping layer, the outside of the core wire winds cordage, and cordage is covered by the first glass-fiber-fabric wrapping layer, and described first It is surrounded with the mica insulation layer being made of mica tape on the outside of glass-fiber-fabric wrapping layer, the outside of the mica insulation layer successively coats There are the second glass-fiber-fabric wrapping layer, armor, shielded layer, the outside of the shielded layer is equipped with polyolefin jacket.

Preferably, armor steel band or steel wire made of weaving forms.

Preferably, the shielded layer is constituted by weaving webbed copper wire.

Preferably, the polyolefin jacket is low-smoke halogen-free polyolefin sheath or pvc sheath.

Preferably, the inner insulating layer is glass-fiber-fabric or Mica tape structure.

Compared with prior art, the utility model has the beneficial effects that

When the utility model is used, can directly buried or installation in the shaft, pass through setting armor and tensile cord The tension and compressive property that cable entirety can be greatly improved, have the advantages that intensity is high, can effectively extend the use of cable Service life；The interference that other instrument or equipment are generated when can effectively reduce cable operation by the way that shielded layer is arranged；Pass through setting Mica insulation layer and inner insulating layer, while improving insulation performance, so that cable has good flameproof effect.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of high-intensitive armouring insulated cable of the utility model.

Fig. 2 is the schematic cross-sectional view of Fig. 1.

In figure, 1, core wire, 2, cordage, the 3, first glass-fiber-fabric wrapping layer, 4, mica insulation layer, the 5, second glass-fiber-fabric is wrapped Layer, 6, armor, 7, shielded layer, 8, polyolefin jacket, 101, tensile cord, 102, twisted wire, 103, inner insulating layer, 104, polyethylene Sheath.

Specific embodiment

Referring to Fig. 1, Fig. 2, a kind of high intensity armouring insulated cable, including core wire 1, armor 6, polyolefin jacket 8, it is special Sign is: the quantity of the core wire 1 is four groups, and the core wire 1 is uniformly arranged in most inner side, and core wire 1 by successively setting from inside to outside The twisted wire 102 set, inner insulating layer 103, pe sheath 104 form, the twisted wire 102 by copper wire and at least one tensile cord 101 twisted compositions, in the first glass-fiber-fabric wrapping layer 3, the outside of the core wire 1 winds cordage 2, fiber for the setting of core wire 1 Rope 2 is covered by the first glass-fiber-fabric wrapping layer 3, and the outside of the first glass-fiber-fabric wrapping layer 3 is surrounded with to be made of mica tape Mica insulation layer 4, the outside of the mica insulation layer 4 is successively coated with the second glass-fiber-fabric wrapping layer 5, armor 6, shielded layer 7, the outside of the shielded layer 7 is equipped with polyolefin jacket 8.

Armor 6 steel band or steel wire made of weaving forms.

The shielded layer 7 is constituted by weaving webbed copper wire.

The polyolefin jacket 8 is low-smoke halogen-free polyolefin sheath or pvc sheath.

The inner insulating layer 103 is glass-fiber-fabric or Mica tape structure.

The working principle of the utility model is:

When the utility model is used, can directly buried or installation in the shaft, pass through setting armor 6 and tensile cord 101 can greatly improve the tension and compressive property of cable entirety, have the advantages that intensity is high, can effectively extend making for cable Use the service life；The interference that other instrument or equipment are generated when can effectively reduce cable operation by the way that shielded layer 7 is arranged；By setting Mica insulation layer 4 and inner insulating layer 3 are set, while improving insulation performance, so that cable has good flameproof effect.

Technical solutions of the utility model are exemplarily described utility model above in conjunction with attached drawing, it is clear that this is practical Novel specific implementation is not subject to the restrictions described above, as long as using the method concept and technical solution progress of the utility model Various unsubstantialities improve, or it is not improved the conception and technical scheme of utility model are directly applied into other occasions, It both is within the protection scope of the present invention.
