Abstract
The utility model relates to a series circuit connecting cable used for ship illumination and being capable of preventing mice or termites biting. A twisted copper conductor is formed by twisting of a plurality of annealed copper wires, and a conductor shielding layer made of semiconductive shielding materials is extruded outside the twisted copper conductor. An insulating layer, a cross-linked polyethylene insulating layer or an ethylene propylene rubber insulating layer, is extruded outside the conductor shielding layer, and the insulating layer is wrapped by a semiconductor shielding band to form an insulating shielding layer. The insulating shielding layer is wrapped by a brass band in an overlapping manner to form a metallic armored shielding layer, which is extruded by a cross-linked polyolefin oversheath. A wrapping semiconductive shielding band serves as an insulating shielding layer is employed, which facilitates peeling the insulating layer and the insulating shielding layer and reducing the bending stress of the cable. The cable is smaller in bending radius. The brass band has shielding effect and is low in cost. The cable is small in external diameter, light in weight, long in service lifetime and safe for use, and is capable of preventing mice or termites biting.
Description
Technical field
The utility model relates to a kind of power cable, particularly the ship's service lighting series circuit stube cable of a kind of mouse bite preventing and termite.
Background technology
Along with the development of boats and ships to maximization, the quantity of lighting is increasing on the boats and ships, thereby requires have more high-tension cable supporting with it, in order to keep the pay(useful) load of boats and ships under the situation that does not increase the cable specification.But all adopt low-voltage cable to be used for connection between ship's service lighting series circuit transformer and the flow straightener in the prior art, and this cause light fixture to bring operation hidden danger at rated power operation in the large ship of majority amount easily.For improving current capacity, common low-voltage cable need strengthen conductor diameter, and adopts two jacket structures, makes the Heavy Weight of cable, and external diameter is big, and bending radius is big, is unfavorable for the instructions for use of boats and ships small space.And the insulation shielding of common low-voltage cable adopts and extrudes semi-conductive shielding material, adopts three-layer co-extruded mode once to extrude with conductor screen and insulation, and insulation shielding peeled off when this kind structure was unfavorable for installing.
The utility model content
The purpose of this utility model is, overcomes problems of the prior art, and the ship's service lighting series circuit stube cable of a kind of mouse bite preventing and termite is provided, and external diameter is little, and is in light weight, is easy to bending.
For realizing above purpose, the ship's service lighting series circuit stube cable of a kind of mouse bite preventing provided by the utility model and termite, many annealed copper skein silks close the formation twisted copper conductors, the periphery of described twisted copper conductors is extruded with semi-conductive shielding material and constitutes conductor shield, the periphery of described conductor shield is extruded with insulating barrier, the periphery of described insulating barrier is surrounded with the semi-conductive screen band and constitutes insulation screen, the periphery of described insulation screen adopts the overlapping wrapped formation metal armouring screen of brass band, and the periphery of described metal armouring screen is extruded with and is added with brightener and shore hardness greater than the cross-linked polyolefin oversheaths of 80 degree.
As preferred version of the present utility model, described insulating barrier is crosslinked polyetylene insulated layer or ethylene propylene rubber insulated layer.
With respect to prior art, the utility model has been obtained following beneficial effect: cable of the present utility model adopts wrapped semi-conductive screen band as insulation screen, insulating barrier and insulation screen peels off when being conducive to cable laying operation, wrapped semi-conductive screen has the stress that is beneficial to when reducing the cable bending simultaneously, makes cable have littler bending radius.The main component of brass is copper and zinc, adopts brass band overlapping wrapped as the metal armouring screen, not only possesses shielding action, can save cost simultaneously.Adopt the cable of 1kV to compare with ship's service lighting cable in the prior art, cable voltage of the present utility model can reach 5kV, can satisfy the high-voltage system instructions for use; Compare with two jacket structures of common midium voltage cable peculiar to vessel, the utility model has adopted no inner sheath structure, thereby makes external diameter littler, and weight is lighter.Under the boats and ships particular surroundings, be added with brightener and shore hardness and can avoid mouse to bait and the erosion of termite moth greater than the cross-linked polyolefin oversheath of 80 degree, make cable have longer useful life, be beneficial to use safety.
Description of drawings
Fig. 1 is the structural representation of the ship's service lighting series circuit stube cable of the utility model mouse bite preventing and termite.
Among the figure: 1. twisted copper conductors; 2. conductor shield; 3. insulating barrier; 4. insulation screen; 5. metal armouring screen; 6. cross-linked polyolefin oversheath.
Embodiment
As shown in Figure 1, the ship's service lighting series circuit stube cable of mouse bite preventing of the present utility model and termite, many annealed copper skein silks close and form twisted copper conductors 1, the periphery of twisted copper conductors 1 is extruded with semi-conductive shielding material and constitutes conductor shield 2, the periphery of conductor shield 2 is extruded with insulating barrier 3, and insulating layer material can adopt crosslinked polyethylene or ethylene-propylene rubber.The periphery of insulating barrier 3 is surrounded with the semi-conductive screen band and constitutes insulation screen 4, the periphery of insulation screen 4 adopts the overlapping wrapped formation metal armouring screen 5 of brass band, and the periphery of metal armouring screen 5 is extruded with and is added with brightener and shore hardness greater than the cross-linked polyolefin oversheaths 6 of 80 degree.
The termite-proof performance of the utility model cable meets 1 grade of moth erosion class requirement among the JB/T 10696.9-2011 " electric wire machinery and physicochemical property test method the 9th part: termite test ".The mouse bite preventing performance meets remarkable grade of degree of protection requirement among the JB/T 10696.10-2011 " electric wire machinery and physicochemical property test method the 10th part: rat bite test ", and protection ratio is not less than 0.9.
The above only is the preferable possible embodiments of the utility model, and is non-so limit to scope of patent protection of the present utility model.In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of the utility model requirement.
