Abstract
The invention discloses a stainless steel sheath power cable. The center of the cable is provided with a conductor; a stainless steel sleeve is sleeved outside the conductor; and a mineral insulation material is injected into a gap between the conductor and the stainless steel sleeve so as to form an insulating layer. The conductor is a solid core copper conductor, the insulation material is the mineral insulation material, namely magnesia powder for electricians, the magnesia insulation material is a recognized safe and reliable insulation material and a stainless pipe is used as a sheath, so the environmental-friendly cable has the advantages of water resistance, fire resistance, explosion resistance, pressure resistance, oil resistance, acid and alkali resistance, high-temperature and low-temperature resistance, no smoke and no toxicity in the real sense, and can be normally used under various environmental conditions. Therefore, the cable has wide using space and market prospect.
Description
Technical field
The present invention relates to a kind of cable, specifically a kind of stainless steel sheath power cable belongs to field of electrical equipment.
Background technology
Existing various power cable, when day-to-day operation, through regular meeting run into as current overload, mechanical collision, the high heat of high temperature, fire disaster, animal bite, factor puzzlements such as long period of soaking, acid and alkali corrosion, and the normal use of influence.
Summary of the invention
It is strong that technical problem to be solved by this invention provides a kind of environmental suitability, the power cable that can normally use under special or extreme environment.
A kind of stainless steel sheath power cable of the present invention, this cable center is a conductor, is with the stainless steel sleeve pipe outside conductor, annotates the bag mineral insulating material in the space between conductor and stainless steel sleeve pipe and forms insulating barrier.
Above-mentioned conductor can be single or many solid copper conductors.
Above-mentioned mineral insulating material is preferably the electrician and insulate with magnesium oxide.
The present invention is with the copper core stainless steel sheath cable of mineral material insulation, that is solution can guarantee the operating characteristic of existing cable, cable is normally used under special or extreme environment, and meet the environmental protection trend that present government advocates, and then a technical problem of meeting the need of market.
This construction of cable will have following advantage:
1, fire performance: can be that the 950-1000 ℃ of 90min that burns down do not puncture by the test of GB/T12666.6-2005A class;
2, ampacity is big: can reduce a cross section, thereby save the consumption of primary raw material copper.
3, anti-mechanical damage: when cable is out of shape suffer bending, flatten, reverse etc., can not produce short circuit, also can not influence electric property.
4, explosion-resistance characteristic: the stainless steel sheath that mineral insulated cable adopts is a seamless copper pipe, can prevent that combustion property gas, oily vapour, flame from entering cable inside.
5, fire resistance characteristic: can long period of soaking in water.
6, corrosion resistance: stainless steel itself has corrosion resistance preferably, under the strong acid-base environmental condition, need not to add other any outer jacket.
7, the life-span is long: under 250 ℃ ambient temperature, and at least can long-time running more than 20 years.
8, Halogen is nontoxic: burning can not produce smog, halogen and toxic gas under 1000 ℃ high temperature
9, anti-overload: overload capacity is strong, and its overload capacity can reach more than 10 times of normal ampacity.
10, cost is low: stainless steel material is compared light specific gravity with copper material, and price is less than half of copper valency, and raw material resources is abundant, and price is more stable for a long time.
Description of drawings
Fig. 1 is a multicore structural representation of the present invention.
Fig. 2 is single core structural representation of the present invention.
Embodiment
As depicted in figs. 1 and 2, a kind of stainless steel sheath cable of the present invention is comprised conductor 1 outward by the lining, and this conductor can be single (Fig. 2) or many (Fig. 1) solid copper conductors; Outside conductor 1, annotate the bag electrician and insulate as insulating barrier 2, add the stainless steel sleeve pipe at insulating barrier and make sheath 3 with magnesium oxide.
Should be pointed out that and to make some improvement and variation that these improvement and variation also should be considered as protection scope of the present invention for the present technique field.
