Technical field:

The utility model relates to a kind of cable, and specifically a kind of kinetic energy of water proof type is controlled compound flat cable.

Background technology:

It not only connects the kinetic energy power supply the compound flat cable of dynamic Control, the transmission of also hold concurrently band signal, control and communication system control signal.Survey under water in the electrical system, transmission of data signals and the water proof type kinetic energy that provides kinetic energy to use such compact conformation always are controlled compound flat cable.Because the particularity of its running environment is very high to the performance requirement of cable.Be characterized in dynamic line and holding wire in the flat cable.Power line provides electric energy for system; Holding wire is that transmission signals is connected with instrument.Have little, the low standing-wave ratio of transmission frequency height, power loss, through-put power is big, watertightness is high, can bear alternating bending, the adverse environment resistant adaptive capacity is strong, has the characteristics of good wear resistance, antitorque commentaries on classics performance.Because of this series products requires very high to its electrical property, mechanical and physical performance, need take all factors into consideration the mutual restriction and the influence of the factor of each side, cable conductor material, insulating material, sheath material, shielding material and the structural design formed have been carried out scientific optimization, to guarantee that cable possesses best technical performance, as far as possible little volume, light as far as possible weight, tool security reliability.

Summary of the invention:

For overcoming the defective of prior art, the purpose of this utility model is to provide that a kind of performance is good, the life-span long, the water proof type kinetic energy of load-carrying properties and excellent in bent-resistant performance is controlled compound flat cable.

The utility model technical solution problem adopts following technical scheme:

A kind of water proof type kinetic energy is controlled compound flat cable, and affiliated flat cable is formed by many power cable cores, master control cable core, parallel the extruding in oversheath of sub-control cable core, and many power cable cores are between master control cable core and the sub-control cable core.

Design feature of the present utility model also is:

Described power cable core is three, parallel extruding in oversheath, and each power cable core from-inner-to-outer is made of tension silk, conductor and insulating barrier.

Described master control cable core is by tension silk that is extruded with the tension insulating barrier and stranded formation of conductor that is extruded with insulating barrier, and the skin of master control cable core is surrounded with water blocking tape layer.

Described sub-control cable core is by many stranded formation of conductor that are extruded with insulating barrier, and stranded gap is filled with the filler that blocks water, and at the wrapped successively polyester belt of the filler skin that blocks water, copper wire establishment screen, extrudes inner sheath.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, the power cable core adopts the thin tinned copper wire conductor of multiply to add tension finer wire combining structure, has not only guaranteed the bending radius of cable, makes cable soft, and has increased the whole resistance to tension of cable core greatly, improves the cable bearing capacity.

2, the higher thin zinc-coated wire of tensile strength that has added strands in the master control cable core, higher because of the tensile strength of finer wire, and percentage elongation is far smaller than copper again, makes the control heart yearn in use not be subjected to the effect of pulling force substantially; The tension silk extrudes corresponding ethylene propylene rubber insulated protective layer outward on the other hand, has protected the insulation of control heart yearn again, prevents finer wire root fracture in crooked use and stabs out the insulating barrier of conductor.Changed the defective that the control heart yearn opens circuit too early in the kinetic energy and control composite cable in the past.

3, power and control cable insulating material adopt fluoroplastics, characteristics are that electric property height, mechanical strength are very high, security reliability is high, insulation thickness programmable relatively thin, the insulation system size is relatively little, resistance to low temperature good, can satisfy the combination property requirement of cable effectively;

4, the sub-control cable core adopts the structure of copper wire braid shielded, and screen extrudes inner sheath outward, not only improves the flexibility of cable, and makes each heart yearn external diameter side by side even relatively, and the serviceability of cable is more stable like this.

5, squeeze before the oversheath side by side three power cable cores and major and minor control cable core between maintain a certain distance, make cable in long-term crooked use, not produce relative slippage, structure is more stable.

6, in tension silk, conductor, the strap that blocks water, the filler that blocks water, polyester belt, copper wire screen, add dubbing.Processes is convenient, and vertically water resistance is good, does not influence the performance and the softness of other composition materials of cable.

7, the utlity model has waterproof, ageing-resistant, oil resistant, excellent serviceability such as corrosion-resistant, and the cable long service life, in the bend test of regulation, the continuous road of insulation heart yearn of cable, not short circuit can not twist into spirality, and oversheath does not damage.
