Abstract
The invention discloses a 45KV single- core cable with high-quality product rate, comprising a conductor, a conductor shielding layer arranged at the outside of the conductor, and an insulation layer arranged at the outside of the conductor shielding layer, a copper wire shielding layer arranged at the outside of the insulation layer, a copper tape shielding layer arranged at the outside of the copper wire shielding layer, a protective covering arranged at the outside of the copper tape shielding layer, and an insulation shielding layer arranged at the outside of the insulation layer, wherein the insulation shielding layer is formed by a plurality of insulation shielding strips which are evenly arranged at the outside of the insulation layer at intervals; and the copper wires of the copper wire shielding layer are evenly sparsely wound on the insulation shielding strips. The 45KV single- core cable with high-quality product rate has the advantages that the transmission capacity is higher and the transmission range is farther compared with those of a common 35KV single-core power cable; the copper wires are ensured to be sparsely wound in the shielding process to avoid generating displacement and being embedded into the insulation layer, thereby ensuring the metallic shielding effects of products, improving the high-quality product rate of the cable, and prolonging the service life of the cable.
Description
Technical field
The present invention relates to a kind of cable, relate in particular to a kind of single-core cable.
Background technology
The electric pressure of common single-core cable is generally 35KV, the structure of existing 35KV single-core cable comprises: conductor, be arranged on the conductor shield in the conductor outside, be arranged on the conductor shield outer insulation, be arranged on the copper wire screen in the insulating barrier outside, be arranged on the copper strips screen and the outer jacket that is arranged on the copper strips screen outside in the copper wire screen outside.Above-mentioned 35KV single-core cable transmission capacity is less, and transmission range is nearer, and the quality percentage of cable is not high.
Summary of the invention
Technical problem to be solved by this invention is: the high 45KV single-core cable of quality percentage that a kind of cable is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: the 45KV single-core cable, comprise: conductor, be arranged on the conductor shield in the conductor outside, be arranged on the insulating barrier in the conductor shield outside, be arranged on the copper wire screen in the insulating barrier outside, be arranged on the copper strips screen and the outer jacket that is arranged on the copper strips screen outside in the copper wire screen outside, the outside at described insulating barrier also is provided with insulation screen, insulation screen is made up of the insulation shielding bar that some spaces evenly are arranged on the insulating barrier outside, and the copper wire of copper wire screen is dredged on the insulation shielding bar equably.
Advantage of the present invention is: above-mentioned 45KV single-core cable is bigger than common 35KV single-core power cables transmission capacity, long transmission distance.Make in the shielding process copper wire guarantee to dredge around, be not subjected to displacement, be unlikely to embed insulating barrier, thereby guaranteed the metallic shield effect of product, improved the quality percentage of cable, prolonged the useful life of cable.
Description of drawings
Fig. 1 is the structural representation of 45KV single-core cable of the present invention.
Fig. 2 is the plan structure schematic diagram of 45KV single-core cable copper wire of the present invention and the winding of insulation shielding bar.
Among the figure: 1, conductor, 2, conductor shield, 3, insulating barrier, 4, the copper wire screen, 41, copper wire, 5, the copper strips screen, 6, outer jacket, 7, insulation screen, 71, the insulation shielding bar.
Embodiment
Describe particular content of the present invention in detail below in conjunction with the drawings and specific embodiments.
As Fig. 1, shown in Figure 2, the 45KV single-core cable, comprise: conductor 1, be arranged on the conductor shield 2 in conductor 1 outside, be arranged on the insulating barrier 3 in conductor shield 2 outsides, be arranged on the copper wire screen 4 in insulating barrier 3 outsides, be arranged on the copper strips screen 5 and the outer jacket 6 that is arranged on copper strips screen 5 outsides in copper wire screen 4 outsides, the outside at described insulating barrier 2 also is provided with insulation screen 7, insulation screen 7 is made up of the insulation shielding bar 71 that some spaces evenly are arranged on insulating barrier 2 outsides, and the copper wire 41 of copper wire screen 4 is dredged on insulation shielding bar 71 equably.
Above-mentioned 45KV single-core cable is bigger than common 35KV single-core power cables transmission capacity, long transmission distance.Make in the shielding process copper wire 41 guarantee to dredge around, be not subjected to displacement, be unlikely to embed insulating barrier 3, thereby guaranteed the metallic shield effect of product, improved the quality percentage of cable, prolonged the useful life of cable.
The foregoing description is only for the usefulness that the present invention is described; and be not to be limitation of the present invention; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the present invention's spirit and protection range; can also make various variations and modification, so all technical schemes that are equal to also should belong to protection category of the present invention.
