Power cable is the cable for transmitting and distributing electric energy, and power cable is usually used in Urban Underground power network, power station
Lead line, the extra large submarine transmission line of industrial and mining enterprises' in-line power and mistake river.
In power circuit, cable proportion just gradually increases.Power cable is in the basic routing line of power system
Cable product to transmit and distribute high-power power, including 1-500KV and any of the above voltage class, various insulation
Power cable.The basic structure of power cable is made up of core, insulating barrier, screen layer and the part of protective layer four.Existing electric power
It is weak to there is pull resistance in cable, is easily broken, the various shortcomings such as water proofing property difference.
The content of the invention
The object of the invention is exactly that there is provided a kind of electricity with multiple rectangular protecting frame framves in order to make up the defect of prior art
Power cable.
The present invention is achieved by the following technical solutions：
A kind of power cable with multiple rectangular protecting frame framves, includes cross section for criss-cross silicon rubber skeleton, ten
Three differ in size the rectangular protecting frame framves be arrangeding in parallel, described rectangle are equipped with four cavitys of font silicon rubber skeleton
The bottom surface of protect-ing frame structure is connected as a single entity with cross silicon rubber skeleton, and quantity is respectively equipped with not inside each rectangular protecting frame frame
Deng core, the described outer wall of core tightly fits with the inwall of rectangular protecting frame frame, described core be by conductor and
What the ethylene propylene diene rubber insulating barrier and compound inslation screen layer being coated on successively on the outside of conductor were constituted, described cross silicon rubber
Glue skeleton, multiple rectangular protecting frame framves and multiple cores constitute cable core, and seamless metal is coated with successively in the outside of cable core
Restrictive coating, carbon black paper insulation screen, semi-conductive buffer water-blocking band layer and three-layer protection layer, in seamless lead alloy sheath layer and
Filled with polyethylene elastic fibers and pyroceram silk mixing packed layer between rectangular protecting frame frame.
Described compound inslation screen layer from inside to outside successively by semiconductive fluorubber internal shield, fluorubber insulating barrier,
Semiconductive fluorubber external shielding layer is constituted.
Three layers of described external protection are followed successively by silver-plated nickel strap armor, butyronitrile insulating barrier and nickel modeling copper strips from inside to outside
Armouring pe sheath layer.
The quantity of core in three rectangular protecting frame framves for differing in size is respectively four, three, one.
Criss-cross silicon rubber skeleton, be equipped with four cavitys of cross silicon rubber skeleton three differ in size it is flat
The rectangular protecting frame frame that row is set, the bottom surface of described rectangular protecting frame frame is connected as a single entity with cross silicon rubber skeleton, every
The core that quantity is not waited is respectively equipped with inside individual rectangular protecting frame frame, core is placed in protect-ing frame structure, one is that can play whole
The arrangement problems of cable internal core is managed, prevents core from sliding, makes structure more neat compact, two be the work for playing protection core
With increasing the pressure-resistant performance of tension of core.
Compound inslation screen layer is from inside to outside successively by semiconductive fluorubber internal shield, fluorubber insulating barrier, semiconductive
Fluorubber external shielding layer is constituted, and semiconductive fluorubber internal shield and semiconductive fluorubber external shielding layer are around pouch-type or extrusion type
Fluorubber material, fluorubber insulating barrier is around pouch-type or extrusion type fluorubber material, it is ensured that cable flexible nature and resistance to height
Temperature characteristics, and the noise signal that cable is produced in itself is minimized.
Semi-conductive buffer water-blocking band is a kind of semi-conductive buffer material water-proof material, is in two layers of semiconductive substrate intermediate adhesion one
The semiconductive material water-proof material of layer is constituted, and it not only has semiconductive property, also to there is buffer pad effect, and the work(that to block water
Can, it is ensured that cable running safety, increase the service life.
Three layers of external protection are followed successively by silver-plated nickel strap armor, butyronitrile insulating barrier and nickel modeling copper strips armouring and gathered from inside to outside
Ethene restrictive coating, more preferably, service life is longer for abrasion resistant effect.
Seamless lead alloy sheath both can be as earth conductor hop short circuit current flow, while can act also as waterproof shield
Layer, it is ensured that cable core conductor can improve sea water corrosion resistant from the wet invasion and attack of moisture water, the pitch of coating.
Polyethylene elastic fibers and pyroceram silk mixing packed layer, while having buffering and resistant to elevated temperatures effect.
It is an advantage of the invention that：Present invention employs rectangular protecting frame frame, for protecting core, core substantially prolongs
Service life, simple in construction, lightweight, pliability is high, and the life-span is longer, corrosion-resistant.
