The core that amount does not wait, the outer wall of described core are tightly bonded with the inwall of rectangular protecting frame frame, and described core is by conductor
And it is coated on ethylene propylene diene rubber insulating barrier on the outside of conductor successively and compound inslation screen layer forms, described cross
Silicon rubber skeleton, multiple rectangular protecting frame framves and multiple cores form cable core, and seamless lead is coated with successively in the outside of cable core
Alloy protective jacket layer, carbon black paper insulation screen, semi-conductive buffer water-blocking band layer and three-layer protection layer, in seamless lead alloy sheath
Polyethylene elastic fibers and pyroceram silk mixing packed layer are filled between layer and 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 forms.
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 to differ 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, bottom surface and the cross silicon rubber skeleton of described rectangular protecting frame frame are connected as a single entity, every
The core that quantity does not wait is respectively equipped with inside individual rectangular protecting frame frame, core is placed in protect-ing frame structure, first, can play whole
The arrangement problems of cable internal core is managed, prevents core from sliding, makes structure more neat compact, second, playing the work of protection core
With increasing the pressure-resistant performance of the 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 forms, and semiconductive fluorubber internal shield and semiconductive fluorubber external shielding layer are around pouch-type or extrusion type
Fluorubber material, fluorubber insulating barrier are around pouch-type or extrusion type fluorubber material, ensure that cable flexible nature and resistance to height
Temperature characteristics, and caused noise signal minimizes in itself by cable.
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 formed, and it not only has semiconductive property, also to there is buffer pad effect, and the work(that to block water
Can, ensure 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, abrasion resistant effect is more preferable, and service life is longer.
Seamless lead alloy sheath can both be used as earth conductor hop short circuit current, while can act also as waterproof shield
Layer, ensure 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 there is buffering and resistant to elevated temperatures effect.
The utility model has the advantages that：The utility model employs rectangular protecting frame frame, for protecting core, greatly prolongs
The service life of core, simple in construction, in light weight, pliability is high, and the life-span is longer, corrosion-resistant.
