In protect-ing frame structure, one is that can play the arrangement problems for arranging cable internal core, prevents core from sliding, makes structure more neat
Compact, two be to play a part of protecting core, increases the pressure-resistant performance of tension of core, and rectangular protecting frame frame and ellipse is used in addition
Circular protect-ing frame structure is used cooperatively, and not only increases the attractive in appearance of structure, and buffering resistance to compression effect is more preferable.
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.
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.
Carbon bellows is using additives such as high density polyethylene (HDPE) raw material and carbon particles, through vacuum suction moulding work
Skill, produces a kind of pipeline with corrugated closed hoop structural pipe wall.With lightweight, bending radius is small, outer pressure resistance
Height, small, corrosion-resistant, non-leakage insulaion resistance, mouse bite preventing, good weatherability, yield are high, meet obstacle reelability etc. series of advantages.
Carbon bellows makes its compressive resistance with its special shape of threads moulding, and shock resistance substantially exceeds GB/T13381.9 technical bids
It is accurate.Light weight and intensity are big, high temperature resistant, corrosion-resistant, length arbitrarily, camber lay traction steel wire freely, in pipe, construction can be made fast
Victory, it is easy to maintenance.Apply inside cable have the advantages that resistance to compression, buffering, it is corrosion-resistant, increase the service life.
Flexible wire ropes wire rope core is organic fiber wire rope core, and inside, elastic fiber material is filled between cover wire rope,
So that steel wire rope has preferable pliability, the problem of existing steel wire rope pliability is low, bending property is poor is efficiently solved.
It is an advantage of the invention that：Rectangular protecting frame frame of the present invention and oval protect-ing frame structure are used cooperatively, for protective wire
Core, buffering resistance to compression effect more preferably, substantially prolongs the service life of core, simple in construction, lightweight, and pliability is high, and the life-span is more
It is long, it is corrosion-resistant.
