Interior some conductor wires 4 and some signal wires 6, signal wire 6 and conductor wire 4 allow electricity successively around inner ring 8 and outer shroud 9 is formed
Cable can have transmission of electricity and transmission signal multiple functions.Secondary shielding layer 7, the He of sheath 1 are provided between inner ring 8 and outer shroud 9
First screen layer 2 can allow the conductor wire 4 of inside and signal wire 6 is able to protection and anti-interference, by secondary shielding layer 7 by signal
Line 6 and conductor wire 4 are isolated, and then signal wire 6 will not be disturbed for conductor wire 4.Between inner ring 8 and outer shroud 9
Filled with polyethylene foamed.Being formed using polyethylene foamed allows cable density to reduce, so that cable can swim in it
On the water surface.
As depicted in figs. 1 and 2, sheath 1 is formed using electro-insulating rubber, and is made of the high material of classification of waterproof, is allowed
Water will not enter inside.First screen layer 2 can be knitted to form using conductive thread 21, and conductive thread 21 is using lighter
Fiber is formed, and can typically use doughnut 22, and on its surface, the conductive metal coating 10 of coating forms conductive thread 21.Together
When, in order to reduce its weight, first screen layer 2 can also be directly using metal coating 10 coated in floating layer 3.In addition, the
Two screen layers 7 are coated using metal coating 10, after inner ring 8 has filled polyethylene foamed composition, are coated in its surface
Metal coating 10, outer shroud 9 is then wound again, refill polyethylene foamed composition, so as to form inner ring 8 and outer shroud 9, and allow interior
Secondary shielding layer 7 is left between ring 8 and outer shroud 9.
Wherein, if as shown in figure 1, floating layer 3 includes internal layer 31, outer layer 32 and for supporting internal layer 31 and outer layer 32
Heavenly Stems and Earthly Branches stay 33, the setting of support bar 33, which allows between internal layer 31, outer layer 32, forms space, so as to make the density ratio of cable relatively low,
So as to which it can be swum on the water surface.In addition, support bar 33 can be arranged to wave structure, its support bar 33 is allowed to internal layer
31 and outer layer 32 support it is more steady.Internal layer 31, outer layer 32 are formed using polyethylene foamed, makes its density ratio relatively low, allows
It more easily can be swum on the water surface.
As shown in figure 1, in order to increase the tensile property of wire, nylon layer is provided with conductor wire 4 and signal wire 6
5, by the intensity of nylon layer 5, improve the resistance of wire.In order to which signal between signal wire 6 will not be interfered, in each signal
Metal coating 10 is coated with line 6, and on the nylon layer 5 coated in signal wire 6.In the present embodiment, metal coating 10 can
To be coated using the one or more in copper, aluminium or silver.
Wherein, the formula of polyethylene foamed is：Polyethylene, crosslinking agent, foaming agent composition.
Foaming agent adopt alkane under azodicarbonamide, dichlorotetra-fluoroethane, trichlorine fluorine, three chlorine fluoroethanes it is therein a kind of or
A variety of compositions.
Crosslinking agent is using ditert-butyl peroxide, cumyl peroxide, 2,5-dimethyl-2,5-di-tert-butyl mistake
Aoxidize hexane, 2,5-dimethyl-2,5-di-tert-butyl peroxidating hexin and 1,3-di-tert-butyl cumene hydroperoxide its
In one or more compositions.
The mass fraction proportioning such as following table of polyethylene, foaming agent and crosslinking agent：
| Polyethylene | Crosslinking agent | Foaming agent | |

Polyethylene is first heated to 110 DEG C of thawings, mixed adding foaming agent and crosslinking agent in proportion successively, due to poly-
Ethene is necessary to ensure that its mobility during stirring, and it fully can be mixed with foaming agent and crosslinking agent, so that
It is stirred under 90 ° or 100 ° of constant temperature, meanwhile, in this process, make foaming agent and crosslinking agent more stable, stir 3min,
Allow it to stir.
After adding foaming agent and crosslinking agent again, then add chopped fiber and mixed, stir can be in the complete short fibre of motor
Carried out after dimension, now, foaming agent, crosslinking agent and chopped fiber can be stirred simultaneously.Can also foaming agent, crosslinking agent with
And polyethylene stir after add chopped fiber, continue to stir 2min or 3min under identical condition, make it well mixed.
Polyethylene and the mass fraction ratio of chopped fiber addition are 5：1, chopped fiber is arranged to coiled structure.
Above-described embodiment 1-9 is carried out to take the material of same shape volume to be tested after foaming as requested, calculates it
Density and tensile strength, control group 1 are foamed using the formula of embodiment 6, but it does not add chopped fiber, and control group 2 is general
Logical polyethylene is test, method of testing according to《GB1040-79 plastic tensile test methods》Carry out, finally measure following table：
| Density（g/cm3） | Tensile strength/MPa | |
| Embodiment 1 | 0.40 | 5.43 |
| Embodiment 2 | 0.49 | 5.98 |
