Abstract
The invention discloses a light-duty compound shore power cable, comprising a cable core; a rubber saddle-shaped strip is positioned in the center of the cable core; the center of the rubber saddle-shaped strip is provided with a circular groove; with the circular groove being the center, three equivalent-distance grooves are arranged; three identical semicircle grooves are arranged on the rims of the rubber saddle-shaped strip; a reinforcement core is positioned inside the circular groove; optical fibers are arranged inside the three equivalent-distance grooves; dynamic wire cores are positioned inside the semicircular grooves; a chlorosulfonated polyethylene inner sheath is extruded on the outside of the cable core; high strength aramid fiber yarn is braided on the outside of the chlorosulfonated polyethylene inner sheath; and a chlorosulfonated polyethylene outer sheath is extruded on the outermost layer. The light-duty compound shore power cable is strong in resisting interference, long in service life, light in weight and big in quantity of signal transmission.
Description
Technical field
The present invention relates to field of cable technology, particularly relate to a kind of light-duty combined type shore connection cable.
Background technology
Boats and ships reach port period, stop using the generator on boats and ships, and use land Power supply instead.Shore connection cable is then the medium connecting harbour power supply unit and transmission facility peculiar to vessel, operating mode due to shore connection cable be often unwinding and rewinding around and be suspended on for a long time on sea, therefore need cable to have external diameter is little, lightweight, Stability Analysis of Structures, weatherability are strong feature, along with the raising of marine technology, shore connection cable also needs the transmission carrying out signal simultaneously.
In order to realize above-mentioned requirements, prior art have employed and is provided with saddle bar at the center of cable, and the employing of signal core is copper conductor, extrude inner sheath again after adopting many signal cores stranded and make holding wire cable core, then the saddle bar gap that is placed in of holding wire and electric power core is carried out stranded side by side, thus achieve the dual-use function that shore connection cable has electric power transfer and Signal transmissions.
In prior art, main Problems existing is as follows:
Adopt prior art, its external diameter is larger; In order to ensure the stable of the construction of cable, be therefore provided with a saddle bar at center, the membership that adds of saddle bar adds external diameter; In addition outside saddle bar, be provided with holding wire cable core, after stranded, external diameter external diameter compared with non-plus signal cable core of cable obviously increases.
Weight penalty: the holding wire core conductor of cable is copper conductor, copper conductor density is large, and heavier-weight, shore connection cable in use needs to use manually to lay, and therefore the cable of heavier-weight is not suitable for installation exercise.
Signal core is low for useful life, weak effect, and signal core cross section is little, long-term unwinding and rewinding around process in the easy fracture of wire of cable signal core, impact use.Signal core does not add shielding, and signal core signal in transmitting procedure is easily interfered.
Summary of the invention
The present invention, in order to solve the problem of prior art, provides and has high life, stable, lightweight, lay and facilitate combined type shore connection cable.
The light-duty combined type shore connection cable of one of the present invention, comprise cable core, arrange rubber saddle type bar at the center of cable core, rubber saddle type bar center is provided with a circular groove, centered by circular groove, be provided with three equidistant grooves, rubber saddle type bar edge is provided with three identical half slots; In circular groove, be provided with strengthening core, in three equidistant grooves, be equipped with optical fiber, in half slot, be provided with power wire core; Outside cable core, extrude chlorosulfonated polyethylene inner sheath, weave high strength aramid yarn outward at chlorosulfonated polyethylene inner sheath, extrude chlorosulfonated polyethylene oversheath at outermost layer.
Further improvement, the diameter of described circular groove is 3-5 times of groove diameter.
Further improvement, described optical fiber angle is each other 120 °.
Further improvement, described power wire core is made up of power conductor and the kinetic insulation layer that is extruded in power guide external.
Further improvement, the diameter of described power wire core is identical with half slot diameter.
Compared with prior art, beneficial effect of the present invention is:
1, optical fiber is extruded in saddle bar, adopt this saddle bar not only not increase the external diameter of cable, and wired signal transmission function can be ensured, and optical fiber has the large feature of working transmission; Optical fiber is the edge being arranged on saddle bar, and therefore stress point is not on optical fiber, can unwinding and rewinding around in well protect optical fiber; Optical fiber has lightweight feature, is arranged the weight that can effectively reduce cable in the cable.
2, in order to increase the tensile property of cable; ensure that cable hangs for a long time across the sea not break down; all reinforced layer is provided with at cable saddle bar center and inner sheath skin; above the reinforced layer of saddle bar to ensure in twisted and released of the cable winding process that cable stress point concentrates on; thus protection power wire core and optical fiber, outside reinforced layer is then improve cable tensile property.
3, the diameter of half slot is identical with the diameter of power wire core, makes power wire core structure in cable core more firm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
The light-duty combined type shore connection cable of one as shown in Figure 1, comprise cable core, arrange rubber saddle type bar 3 at the center of cable core, rubber saddle type bar 3 center is provided with a circular groove, centered by circular groove, be provided with three equidistant grooves, rubber saddle type bar edge is provided with three identical half slots; In circular groove, be provided with strengthening core 4, in three equidistant grooves, be equipped with optical fiber 5, in half slot, be provided with power wire core; Outside cable core, extrude chlorosulfonated polyethylene inner sheath 6, at chlorosulfonated polyethylene inner sheath 6 outer braiding high strength aramid yarn 7, extrude chlorosulfonated polyethylene oversheath 8 at outermost layer.
Described power wire core is made up of power conductor 1 and the kinetic insulation layer 2 be extruded in outside power conductor 1.
The diameter of described circular groove is 3-5 times of groove diameter, and the diameter of circular groove is 3-5mm.
Described optical fiber 5 according to 120 ° mode be staggeredly arranged in groove, form an equilateral triangle, make the structure of cable more stable, firmly.
The diameter of described power wire core is identical with half slot diameter, makes power wire core structure in cable core more firm.
Embody rule approach of the present invention is a lot, and the above is only the preferred embodiment of the present invention, should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
