Description

Light power cable

Technical Field

The utility model relates to a power cable technical field specifically is a light-duty power cable.

Background

Along with the rapid development of scientific technology and the continuous improvement of automation degree, the automation and intellectualization level of ships is higher and higher, and the electric instruments matched with the ships are also increased. Due to the special use place of the cable for ships, the cable needs to be small in size, light in weight and good in flexibility in order to bear more materials.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a simple structure, light in weight and the good light-duty power cable of compliance.

Realize the utility model discloses the basic technical scheme of purpose is: a light power cable is structurally characterized in that: including the principal conductor core, around covering and oversheath. The main line core has 3, and 3 main line cores's structure is the same, all includes conductor and insulating layer. The conductor is made of an aluminum alloy material. The insulating layer is extruded outside the conductor by adopting cross-linked polyethylene. 3 main core transposition stranding is cabled yarn, adopts lightweight high strength metal fiber cloth to wind the package after the cabled yarn and forms around the covering, and every layer is lapped to take the lid rate to be 50% around the package. The outer sheath is extruded outside the wrapping layer by adopting cross-linked polyolefin.

The utility model discloses following beneficial effect has: (1) the utility model discloses a light-duty power cable uses aluminum alloy material as the main line core conductor, its 1/3 of weight when only being original use copper product in the aspect of weight, and the whole weight reduction of joining in marriage means the bearing material that can be more. In the process of installing and laying the cable on a ship, the aluminum alloy conductor is used instead of the aluminum conductor, so that the creep resistance of the conductor can be effectively improved. (2) The utility model discloses a light-duty power cable's insulating layer uses crosslinked polyethylene (XLPE) insulating, and density ratio ordinary Ethylene Propylene Rubber (EPR) is insulating to be reduced 30%, has further alleviateed cable weight. (3) The utility model discloses a light-duty power cable uses lightweight high strength metal fiber cloth around the covering, and it possesses the performance that bears powerful load, tensile modulus is big, the elongation is little, light, pliable and tough, resistant buckling, and the cable weight when adopting the copper product to weave the structure as the armor more originally further reduces. The metal fiber cloth has strong electromagnetic compatibility, effectively shields the interference of an electromagnetic field generated by the cable to other precise equipment, and can prevent the electromagnetic field generated by other cables and equipment from being unbalanced due to radiation. (4) The utility model discloses a light-duty power cable's oversheath uses crosslinked polyolefin (SHF 2) material, can play resistant oily, resistant UV, protection such as moisture resistance, is favorable to improving its life.

Drawings

Fig. 1 is a schematic structural view of the light power cable of the present invention.

The reference numbers in the drawings are:

the cable comprises a main wire core 1, conductors 1-1, insulating layers 1-2, a wrapping layer 2 and an outer sheath 3.

Detailed Description

(example 1)

See fig. 1, the utility model discloses a light-duty power cable includes the main line core 1, around covering 2 and oversheath 3.

The main wire core 1 is provided with 3 main wire cores 1, the 3 main wire cores 1 have the same structure and respectively comprise a conductor 1-1 and an insulating layer 1-2. The conductor 1-1 is made of 8030 aluminum alloy material and meets the requirement of GB 3956. The insulating layer 1-2 is extruded outside the conductor 1-1 by adopting cross-linked polyethylene (XLPE). 3 main core 1 according to right transposition stranding, adopt lightweight high strength metal fiber cloth to wind after the stranding and form around covering 2, every layer is lapped the lid and is 50%, and this embodiment adopts Shenzhen city hua li da stainless steel fiber limited 316L stainless steel fiber cloth to wind and form around covering 2. The outer sheath 3 is extruded outside the wrapping layer 2 by adopting cross-linked polyolefin (SHF 2).
