Abstract
The utility model relates to an improved armored cable, particularly an armored cable with strong pressing resistance and stretching resistance. The utility model is characterized in that an armoring layer is made of carbon fiber composite material, and is directly armoured outside cable cores. The utility model has simple structure, omits an inner protection layer and reduces the production cost. After armored, the compression resistance of the utility model is larger than that of a steel belt at three to four times, the stretching resistance is larger than that of a steel wire at two to three times, the strength of the utility model can reach 2399MPa (the steel wire armoring strength is at 1240MPa), thereby, the cable enhances safety. The armored cable has small linear expansion coefficient, and the cable laxation degree variation quantity is at 9.6% of a conventional steel wire armored cable. Because of the carbon fiber composite material armoring layer, the cable has good flexibility and basically can meet the construction requirements for bending. Because of the carbon fiber composite material armoring layer, the utility model has strong corrosion resistance, has good affinity for environment and sheaths, can not bring about corrosion and rusting and prolongs the service life of the cable. The armoring layer has good insulating property, and greatly enhances the running safety of the cable.
Description
Technical field
Utility model is about the improvement to cable armouring, relates in particular to a kind of resistance to compression and the strong armoured cable of stretching resistance ability.
Background technology
For improving cable opposing external force (resistance to compression and tension) ability, strengthen cable intensity, adopt metal (steel band or steel wire) armouring usually.Cable is with wrapped (or the steel wire winding) armouring of steel band (hereinafter to be referred as metal armouring), and its anti-pressure ability improves still limited, is subjected to the external force effect still yielding, and the armouring metal can puncture insulation and cause the damage of cable when serious.For example machinery weighs wounded and causes cable short circuit in construction; And uncertain natural calamity causes building collapsing to weigh cable wounded to cause transmission of electricity to be interrupted, and this type of accident is more and more.Secondly, the cable metal armouring, tensile strength is still less than normal, has only usually about 1300Mpa, can not bear big pulling force; And be affected by thermal expansion and contraction, erecting cable degree of speeding is big, and the span spacing is little, and span is restricted, and not only causes the construction cost height, and is difficult to set up in some occasion (as crossing river, extra large excessively).Besides, the steel wire of armouring or steel band and environment and relatively poor with the compatibility of sheath material, especially environment or sheath and steel wire or steel band are easy to generate cell reaction and get rusty, and cause getting rusty of armour, shorten the useful life of cable.In addition, cable causes oversheath to pull open at work progress easily, and steel band that exposes or steel wire can cause certain potential safety hazard to the workmen.Metal armouring, the cable bending property is poor, also is unfavorable for the cable laying construction.
For preventing that the armouring metal from puncturing insulation, metal armouring must add sheath in armour, increased cable cost again, sets up sheath increase cost and is about about 5-6%.
Goal of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, and a kind of not only good bending property is provided, and tensile strength and resistance to compression are big, and armouring does not need the armoured cable of sheath.
The utility model purpose realizes that main the improvement is to omit the armouring sheath, adopts the carbon fibre composite armour, thereby overcomes the deficiency of prior art, realizes the object of the invention.Specifically, the utility model armoured cable comprises cable conductor and armour and outer jacket, it is characterized in that said armour is a carbon fibre composite, and directly armouring is outside cable core.
The said carbon fibre composite of utility model, by carbon fiber wire and other inorganic material filaments for example glass fiber mix, and by the band shape (is that 0.2～0.8mm, width are 15～80mm strip such as but not limited to thickness) or the pencil rod (is pole or the approximate pole of 1.5～6.0mm such as but not limited to diameter) of thermosetting resin cured one-tenth.Carbon fiber, inorfil, thermosetting resin three ratio, equilibrium price and performance, a kind of carbon fiber 20%～40%wt that is preferably; Glass fibre 40～75%wt; Epoxide resin 5%～20%wt.Armouring, according to the carbon fibre composite shape, can be wrapped, also can be around vertically arranging, tightening.
Utility model is owing to adopt carbon fiber to become band or thin rod with inorfil and by resin solidification, directly armouring is outside cable core, not only simplify the structure, omitted sheath, reduced production cost, and withstand voltage behind the armouring greater than 3～4 times of steel bands, anti-widening in 2～3 times on steel wire, intensity can reach 2399Mpa (wire armoring intensity is 1240MPa), has strengthened the fail safe of cable greatly.Secondly, the gained armoured cable, coefficient of linear expansion is little, and cable degree of speeding variable quantity only is 9.6% of a conventional steel wire armored cable.Besides, the carbon fibre composite armouring, the cable good bandability can satisfy the requirement of construction to flexibility substantially.The carbon fibre composite armouring, corrosion resistance is strong, and is good to environment and sheath affinity, prolonged the useful life of cable again.Armour has good insulating properties, has also improved the fail safe of cable operation by a relatively large margin.Utility model can be used for various armatures of cable.
Below in conjunction with two embodiments, further specify the utility model structure.
Description of drawings
Fig. 1 is the first embodiment armoured cable schematic cross-section.
Fig. 2 is the second embodiment armoured cable schematic cross-section.
Embodiment
Embodiment 1: referring to Fig. 1, the utility model armoured cable is formed insulated wire cores by conductor 1, conductor insulation 2, and three thoroughly do away with the edge core arranges stranded stranding by 120 °, and clearance filled filling 3 is tightened by tightening layer 4 outward, forms cable conductor.With carbon fiber 35%; Glass fibre 55%; Epoxide resin 10% is solidified into the pole of 1.5～6.0mm, and it is stranded vertically to arrange spiral around cable core, forms armour 5, and outer jacket 6 is arranged outward.
Embodiment 2: referring to Fig. 2, as embodiment 1, armour 7 is by 28% carbon fiber, 60% glass fibre, 12% epoxy resin, and mixing cured one-tenth thickness is that 0.2～0.8mm, width are the carbon fibre composite band of 15～80mm, directly be wound in and tighten outside the cable core, outer jacket 6 is arranged outward.
