Abstract

The utility model discloses a wind-power cable with a rated voltage of 0.6-1KV for wind power generation. The wind-power cable comprises a cable core, and the cable core consists of an annealing soft copper line conductor and an insulation layer of a irradiating cross-linked low-smoke halogen-free polyolefin insulating material which is packed outside the conductor; and an oxygen insulation layer of a low-smoke halogen-free irradiating cross-linked polyolefin jacket material is extruded outside the cable core, and an outer jacket of low-smoke halogen-free irradiating cross-linked polyolefin jacket material is extruded on the outermost layer. By the adoption of the wind-power cable, heat environment resistance and insulating performance of the cable are improved, the application scope is wide, and the safety performance is better.

Description

A kind of Wind power cable

Technical field

The utility model relates to the electric wire field, specifically refers to a kind of rated voltage 0.6/1KV power cable for wind power generation.

Background technology

The energy is the important substance basis of socio-economic development, realize growing continuously and fast of ambitious goal that China GDP in 2020 quadruples and national economy, only depends on conventional energy resource to be difficult to solve the energy and electricity shortage.Account for coal electricity fuel---the coal of supply of electric power 70 %, the residue mine reserves of verifying is 1,390 hundred million t, by 2003 yearly off-take rates, 16.67 hundred million t/a, only can keep 83a, also will bring serious environmental pollution.The petroleum resources of China are not enough, and natural gas resource is also abundant not, the natural uranium shortage of resources.

The wind energy resources of China is very abundant, estimate according to National Meteorological Bureau, China 10 m height is about 1,000,000,000 kW with the interior earth surface wind electric energy that develops, land 2.5 hundred million kW wherein, marine 7.5 hundred million kW, if expand to the above height of 50～60 m, wind resource will be expected to expand to 20～2,500,000,000 kW.Therefore, wind power generation is the reality of China's energy sustainable development and important selection.

At present, domestic power cable for wind power generation major part is as main take 1KV and following electric pressure, product is mainly take import as main, the 1st or the 2nd kind of conductor in the GB/T3956-97 standard as core, low-smoke halogen-free material as insulation, low-smoke halogen-free material is as sheath, the domestic cable of the type has affected the development of wind-powered electricity generation because insulation property, the environmental resistance of insulating material are relatively poor.

The utility model content

The technical problems to be solved in the utility model provides a kind of rated voltage 0.6/1KV power cable for wind power generation that improves heat-resisting environmental performance, security performance and the insulation property of cable.

A kind of Wind power cable described in the utility model comprises cable core, and its cable core is made of the conductor insulating barrier outer with being extruded in conductor; Extrude oxygen barrier layer outside cable core, outermost layer extrudes oversheath.

It is stranded the forming of annealed copper line of TR that described conductor adopts the multiply code name.

The beneficial effects of the utility model are:

By the soft copper skein silk is closed the formation conductor; the cable conductor extruded insulation; make cable have simultaneously preferably fire resistance and insulation property, extrude low smoke and zero halogen irradiation crosslinked polyolefin insulating material at cable core again and protect as oxygen barrier layer, make cable have preferably environmental resistance.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Embodiment:

As shown in Figure 1, a kind of Wind power cable described in the utility model comprises cable core, and its cable core is made of conductor 1 and the insulating barrier 2 that is extruded in outside the conductor 1; Extrude oxygen barrier layer 3 outside cable core, outermost layer extrudes oversheath 4.

Manufacture method of the present utility model is: the insulating barrier 2 that extrudes first the low-smoke halogen-free polyolefin Insulation Material at stranded good annealed copper line conductor 1; form cable core; then cable core is twisted into cable core; outside cable conductor, extrude again low smoke and zero halogen cross-linked polyolefin Insulation Material as oxygen barrier layer 3 protections; extrude at last low smoke and zero halogen cross-linking radiation polyolefin jacket material as oversheath 4 protective layers, formed rated voltage 0.6/1KV power cable for wind power generation.

Rated voltage 0.6/1KV power cable for wind power generation as shown in the figure can adopt following procedure of processing to make: first will be as the annealed copper line 1250C low-smoke halogen-free flame-retardant isolating irradiation material of conductor 1, form insulating barrier 2, insulation should be even, smooth, bright and clean, to form the cable core twisted synthesizing cable by conductor 1 and insulating barrier 2 again, form the cable base, outside this cable base, extrude the K1 class nuclear power low smoke and zero halogen of anti-irradiation oxygen barrier layer flame-proof material as oxygen barrier layer 3, outside oxygen barrier layer 3, extrude equably one deck 1250C low-smoke and halogen-free flame retardant polyolefin jacket irradiation material and consist of restrictive coating 4.

The utility model provides a kind of Wind power cable version and implementation method; the above only is preferred implementation method of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.

Claims

1. a Wind power cable comprises cable core, it is characterized in that: its cable core is by conductor (1) and be extruded in outer insulating barrier (2) formation of conductor (1); Extrude oxygen barrier layer (3) outside cable core, outermost layer extrudes oversheath (4).
