Abstract
The utility model discloses a shore connection cable for ships, belonging to the field of cables. The shore connection cable comprises an insulating core wire harness, wherein the insulating core wire harness is formed by stranding a plurality of insulating core wires, each insulating core wire comprises a conductor and an insulating layer, a filling core is arranged in the central gap of the insulating core wire harness, an isolation wrapping belt is wound outside each conductor, the insulating layer is wrapped outside the isolation wrapping belts, an inner sheath is extruded outside the insulating core wire harness, and an outer sheath is extruded outside the inner sheath. By arranging the isolation wrapping belts outside the conductors, the insulating layers are separated from the conductors and easy to be stripped off. By adopting the double-layer extrusion mode, the internal stresses of the sheaths are eliminated so that the mechanical strength of the cable is increased. The shore connection cable can be applied to the ship or ocean engineering.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of boats and ships shore connection cable.
Background technology
Prior art discloses a kind of shore connection cable peculiar to vessel, publication number: CN2736894, mainly constitute by oversheath, lapping layer, insulating barrier, packed layer, cored wire conductor, insulating barrier is arranged on outside each cored wire conductor, lapping layer is wrapped outside multiply has the cored wire conductor of insulating barrier, be provided with packed layer between the insulating barrier and between insulating barrier and the lapping layer, packed layer is connected as a single entity, lapping layer is provided with oversheath outward, its weak point is: described insulating barrier easily is absorbed in the slit of stranded conductor, be not easy to peel off insulating barrier, and poor radiation; When shipboard cable uses, the easier cable tensile strain that causes of its operating state.
The utility model content
The purpose of this utility model is to provide a kind of boats and ships shore connection cable, makes to peel off insulating barrier convenience, easy to operate, eliminates the internal stress of sheath, has improved the mechanical strength of cable.
For solving above technical problem, the utility model provides a kind of boats and ships shore connection cable, comprise the insulating core wire harness, described insulating core wire harness is insulated by multiply, and heart yearn is stranded to form, and per share insulation heart yearn comprises conductor and insulating barrier, and described insulating core wire harness center gap place is provided with filled core, described conductor is surrounded with the isolation band outward, described isolation band external packets is covered with described insulating barrier, and described insulating core wire harness is extruded with inner sheath outward, and inner sheath is extruded with oversheath outward.
With respect to prior art, the utility model has been obtained following beneficial effect: the utility model is provided with the isolation band between conductor and insulating barrier, outside the insulating core wire harness, be extruded with inner sheath, inner sheath is extruded with oversheath outward, make that the insulating barrier of peeling off outside the conductor is convenient, easy to operate, strengthen the conductor heat dispersion, be convenient to the energising heat radiation of cable; The filled core that is arranged on insulating core wire harness center makes the mechanical strength of cable be improved.The utility model can be used in boats and ships or the ocean engineering.
As improvement of the present utility model, described conductor is that diameter is that the tin-coated copper tow strand of 0.5mm forms.
