Abstract
The utility model relates to the field of household communication and power equipment, and particularly relates to a high-strength composite cable for offshore drilling. The high-strength composite cable for offshore drilling comprises a flexible-wire conductor, an anti-tensile steel wire, an insulating layer, grounding wires, a filler, an inner sheath, a shield-armour layer and an outer sheath, wherein the flexible-wire conductor is externally lapped with the insulating layer to form a cable core; the two cable cores and one grounding wire are lapped by an aluminium foil as a group to form a core wire; a plurality of the core wires are twisted to form a cable and then sequentially lapped with the inner sheath, the shield-armour layer and the outer sheath from inside to outside; the filler is filled in gaps among the core wires; the anti-tensile steel wire is arranged in the outer sheath; and the outer sheath is made from vulcanizated styrene-butadiene rubber. According to the high-strength composite cable for offshore drilling disclosed by the utility model, the outer sheath is made from vulcanizated styrene-butadiene rubber and internally provided with the anti-tensile steel wire to enhance the anti-tensile strength, so that the cable is excellent in electrical performance, low in cost and convenient to use while the normal working of the cable during offshore oil exploitation is ensured.
Description
Technical field
The utility model relates to family expenses communication electric power equipment field, relates in particular to a kind of composite cable.
Background technology
Increasing along with people's demand to information in productive life, more and more widely, mechanics of communication is advanced by leaps and bounds, and presents information technology prosperity scene in the ascendant.Extensively adopt in each field under the demand of information technology, should need and the communication product of giving birth to is broken through the soil one after another like rain the back spring bamboo.Yet, on the great equipments such as the Aero-Space high in big, the fire-retardant requirement of high low temperature difference variation, that communicating requirement is strict, naval vessel, offshore platform, oil exploration, power plant, little because of the communication products demand, quality requirement is strict, performance constantly changes requirement because occasion is different, so far aspect high-end communication products especially communications cable product aspect also form industry standard and the product line of specialty.
Existing ocean engineering, large scale electrical power unit, oil production equipment, large-scale suspender or supervisory control system generally adopt separate cable system, this class cable is mostly main considers electric power conveying, communication, performance such as anti-interference, tensile strength to cable itself is not special attention, tensile strength has just just satisfied basic standard mostly, when cable has specific demand, use the cable of regular tenacity, reliability will be affected.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of high strength offshore drilling composite cable, this cable utilizes corrosion resistant sulfuration butadiene-styrene rubber as oversheath, and tension steel wire increase tensile strength is set in oversheath, guaranteed the operate as normal of cable under specific condition.
The utility model is achieved in that a kind of high strength offshore drilling composite cable, comprise soft silk conductor, the tension steel wire, insulating barrier, earth connection, filler, inner sheath, shield layer and oversheath, behind the outer lapped insulation layer of described soft silk conductor as cable core, two cable cores and an earth connection as one group by the wrapped heart yearn that shields into of aluminium foil, wrapped inner sheath in turn from inside to outside behind the some stranded strandings of heart yearn, shield layer and oversheath, described filler is filled in the space between the heart yearn, described tension steel wire is arranged in the oversheath, and described oversheath is sulfuration butadiene-styrene rubber.
Described soft silk conductor is zinc-plated stranded soft copper silk conductor.
Described insulating barrier is the PET nonwoven fabrics.
Described filler is polypropylene flame redardant.
Described inner sheath is flame retardant rubber.
Described shield layer is the zinc-coated wire braid.
This utilizes corrosion resistant sulfuration butadiene-styrene rubber as oversheath with composite cable in the utility model high strength offshore drilling, and the tension steel wire is set in oversheath increases tensile strength, can bear the load more than 3000 kilograms, guaranteeing that cable can operate as normal when submarine oil is exploited, has excellent electric property, signal transmission frequency height, shield effectiveness is good, and anti-electromagnetic interference capability is strong; Its volume is little, in light weight, it is little to take up room, cost is low, the convenient use.
Description of drawings
Fig. 1 is the utility model high strength offshore drilling composite cable schematic cross-section;
Among the figure: 1 soft conductor, 2 tension steel wires, 3 insulating barriers, 4 earth connections, 5 fillers, 6 inner sheaths, 7 shield layers, 8 oversheaths, 9 aluminium foils.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model statement, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, a kind of high strength offshore drilling composite cable, comprise soft silk conductor 1, tension steel wire 2, insulating barrier 3, earth connection 4, filler 5, inner sheath 6, shield layer 7 and oversheath 8, described soft silk conductor 1 outer lapped insulation layer 3 back are as cable core, two cable cores and an earth connection 4 as one group by the aluminium foil 9 wrapped heart yearns that shield into, the thickness of aluminium foil 9 about 0.05mm, guarantees that heart yearn does not have the electromagnetic interference influence at 600MHz with super band usually; From inside to outside wrapped inner sheath 6, shield layer 7 and oversheath 8 in turn behind the some stranded strandings of heart yearn, described filler 5 is filled in the space between the heart yearn, described tension steel wire 2 is arranged in the oversheath 8, described oversheath 8 is corrosion resistant sulfuration butadiene-styrene rubber, about oversheath 8 thickness 0.40~1mm, select according to the environment for use difference, tension steel wire 2 increases the tensile strength of oversheath 8, and then improves the tensile strength of this cable.
The utility model can further describe into, described soft silk conductor 1 is zinc-plated stranded soft copper silk conductor, described insulating barrier 3 is the PET nonwoven fabrics.
In the present embodiment; filler 5 between the heart yearn is polypropylene flame redardant; outer wrapped one deck flame retardant rubber is as inner sheath 6 during stranded stranding; the inner sheath 6 main protective effects that rise inner pair of twisted cores line, the thickness of inner sheath 6 is done the time spent as external force about 0.15mm; can play the power recoil effect of letting out; inner sheath 6 outsourcings are shielded by the shield layer 7 of zinc-coated wire braiding, and shielding density reduces the interference of external signal more than 85%.
