Abstract
The utility model discloses a kind of Anti-pressure cross-linked polyethylene insulation flame-retardant power cable, include the oversheath of flame-proof polyvinyl chloride material, the first armor on the inside of oversheath, positioned at the first inner liner of first armoured layer of internal layer, the second armor on the inside of the first inner liner, the second inner liner on the inside of the second armor, twining package tape on the inside of the second inner liner, the twining package tape is coated with multiple copper conductors, each copper conductor is coated with crosslinked polyetylene insulated layer, it is coated between the copper conductor of crosslinked polyetylene insulated layer and is filled with gasket for packing.The utility model adds the anti-pressure ability of cable using double armor layer, by the setting of double layer innerliner layer, greatly strengthen influence of the ambient pressure to cable, and using the oversheath of flame-proof polyvinyl chloride material so that cable has fire resistance.
Description
Technical field
It the utility model is related to field of cable technology, and in particular to a kind of Anti-pressure cross-linking polyethylene insulated fire resistant electric power electricity
Cable.
Background technology
Insulation PVC sheath armoured power cable is used to exchange 50HZ, rated voltage (U0/U) 0.6/1kv and following
In power circuit, supply and used with electric energy.Use characteristic：The highest rated temperature of cable conductor is 70 DEG C.When short-circuit (when most long lasting
Between be no more than 5S) maximum temperature of cable conductor is no more than 160 DEG C；If environment temperature during cable should be not less than 0 DEG C, it is minimum
Bending radius is not less than 15 times of the outside diameter of cable.Conventional armoured power cable structure is that wrapped clad steel band carries out armouring, in electricity
Because construction wrong often results in cable bad when cable is constructed, the use of cable is influenceed.Applicant's application in 2012 proposes a kind of anti-
Die mould power cable, including pe sheath, armor, multiply copper conductor, outer surface of copper conductor cladding are crosslinked polyetylene insulated
Gasket for packing between layer and conductor, the armor is individual layer interlocking armor.Gather provided with foam the armor lower surface
Ethene is around packet mode sheath.Armature of cable is carried out using one layer of overlapping wrapped lock armo mode, increases cable compressive property,
Cable uses the sheath of wrapped foamed polyethylene material, reduces damage of the pressure in the external world to cable insulation, is asked with solving this
Topic, but this cable, in actual application, compressive property needs further to be improved, in addition, fire resistance and buffering
Poor performance is, it is necessary to further improve.
Utility model content
The purpose of this utility model is to be directed to technological deficiency present in prior art, and it is poly- to provide a kind of Anti-pressure crosslinking
Ethene flame-resistant insulation power cable.
Technical scheme is used by realize the purpose of this utility model：
A kind of Anti-pressure cross-linked polyethylene insulation flame-retardant power cable, including the oversheath of flame-proof polyvinyl chloride material, position
The first armor on the inside of oversheath, the first inner liner positioned at first armoured layer of internal layer, on the inside of the first inner liner
The second armor, the second inner liner on the inside of the second armor, positioned at the second liner lead inner side twining package tape, it is described around
Band is coated with multiple copper conductors, and each copper conductor is coated with crosslinked polyetylene insulated layer, is coated with crosslinked polyethylene
Gasket for packing is filled between the copper conductor of insulating barrier.
First armor, the second armor are individual layer lock armo layer, and first inner liner is with the second liner
PP foamed material layers.
Technical scheme of the utility model more than, the anti-pressure ability of cable is added using double armor layer, is passed through
The setting of double layer innerliner layer, influence of the ambient pressure to cable is greatly strengthen, and using the outer shield of flame-proof polyvinyl chloride material
Set so that cable has fire resistance, and the cable-flame retardant is good, pressure resistance.
Brief description of the drawings
Fig. 1 is the structural representation of Anti-pressure cross-linked polyethylene insulation flame-retardant power cable.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description only to explain the utility model, is not used to limit the utility model.
It is shown in Figure 1, a kind of Anti-pressure cross-linked polyethylene insulation flame-retardant power cable, including flame-proof polyvinyl chloride material
Oversheath 1, the first armor 2 on the inside of oversheath, the first inner liner 3 positioned at first armoured layer of internal layer, be located at
The second armor 4 on the inside of first inner liner, the second inner liner 5 on the inside of the second armor, led positioned at the second liner interior
The twining package tape 6 of side, the twining package tape are coated with multiple copper conductors 8, and each copper conductor is coated with crosslinked polyetylene insulated
Layer 7, it is coated between the copper conductor of crosslinked polyetylene insulated layer and is filled with gasket for packing 9.
First armor, the second armor are individual layer lock armo layer, using aluminum alloy strip, first inner liner
It is PP foamed material layers with the second liner.
The consistency of thickness of first inner liner and the second liner, first armor, the thickness one of the second armor
Cause, the thickness of the oversheath be first armor, 2.5-3 times of thickness of the second armor, first inner liner
With the thickness of the second inner liner, with first armor, the consistency of thickness of the second armor, the thickness of the twining package tape and
The consistency of thickness of one inner liner, crosslinked polyetylene insulated layer.
The gasket for packing is polypropylene PP filling rope, and it is non-woven fabrics or plastic cloth that the twining package tape, which uses,.The polypropylene
PP filling rope has good electric insulating quality and flexibility, long-term to fill imputrescibility in the cable.
Technical scheme of the utility model more than, the anti-pressure ability of cable is added using double armor layer, is passed through
The setting of double layer innerliner layer, influence of the ambient pressure to cable is greatly strengthen, and using the outer shield of flame-proof polyvinyl chloride material
Set so that cable has fire resistance, and the cable-flame retardant is good, pressure resistance.
Described above is only preferred embodiment of the present utility model, it is noted that for the general of the art
For logical technical staff, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these change
Enter and retouch and also should be regarded as the scope of protection of the utility model.
