Description
Technical field
The utility model relates to a kind of packings, and in particular to a kind of submarine cable packing.
Background technique
With the development of ocean wind-powered electricity generation and national economy, the demand to submarine cable is also increasing, while to its work
Reliability and the feature of environmental protection require it is also higher and higher.
The existing general 35kV of submarine cable and following voltage class mostly use polypropylene mesh tear rope to fill, 35kV or more
For voltage class since conductor assembly outer diameter is big, stranding post gap is big, polypropylene mesh tear rope it is difficult to ensure that submarine cable roundness, because
This 35kV above mostly uses molding packing structure, and existing submarine cable packing mostly uses feed back is secondary to add
Work, rough, substance is big, and waste of resource, increases manufacturing cost, does not meet the development strategy of National Environmental friendly
It is required that.
Existing submarine cable packing usually contains the substance of more hostile environment, and substance is larger, smell is big,
Not only harmful to environment but also waste of resource increases sea cable cost, rough, and when stranding is easier to cause stranding non-round
It is whole, band is damaged, squeezes phenomena such as fiber unit, bring bigger difficulty to manufacturing, while quality also resulted in product
Hidden danger reduces its longtime running functional reliability.
Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome deficiencies in the prior art, provide a kind of intensity height, patch

Section, the lower part of the inner arc section composition packing, the top of the outer arcuate section and arc groove section composition packing, upper
Several supporting sections are equipped between portion and lower part.
The inner arc section, outer arcuate section, arc groove section and supporting section are an integral structure.
The inner arc section is bonded setting with inner sheath outer wall.
The outer arcuate section is located on the circular section of inner sheath and packing composition.
The inner arc section, outer arcuate section, the junction between arc groove section are all made of round-corner transition connection.
The diameter that horizontal distance between the upper port of the arc groove section is less than or equal to circumference locating for arc groove is long
Degree.
Optical fiber is placed in the arc groove section.
The supporting section is between each other using intersection or/and parallel construction, wherein parallel for laterally or longitudinally direction.
When supporting section intersects, it is symmetrical that several are formed between inner arc section, outer arcuate section, arc groove section
The triangle of distribution or trapezoidal skeleton structure, skeleton are hollow structure.
The utility model has the advantages that the utility model is compared with prior art, remarkable advantage is: the setting of the utility model overall structure
Rationally, inner arc section, outer arcuate section, arc groove section and supporting section are integrally formed composition packing, inner arc section and inner sheath
Outer wall fitting setting, outer arcuate section are located on the circular section of inner sheath and packing composition, and filling effect is good, rounding property, support
Power, intensity are preferable, and whole to use PE, environment friendly and pollution-free, molded surface is smooth, packing according to cable core and fiber unit not
Outer diameter is calculated after same specification size and stranding and designs different size compact dimensions, and arc groove section is set on outer segmental arc, is used
In placement fiber unit, and the horizontal distance between the upper port of arc groove section is less than or equal to circumference locating for arc groove
Diameter length, it is ensured that the fixed not positioning of optical fiber, while not near avoiding from each other dry between fiber unit and conductor thread core
Influence is disturbed, further increases safety in utilization, by several symmetrical triangles and trapezoidal skeletal support, branch inside packing
Support bone frame quantity and direction can need intensity to be adjusted according to packing, guarantee uniform force, indeformable after armouring, effectively
Resistance to deformation amount is promoted, prevents the excessive damage for causing core, optical fiber of external force, while skeleton is hollow structure, can effectively reduce electricity
Cable weight saves material, with good economic efficiency.
