Description
Technical field
The utility model belongs to power cable field, particularly relates to a kind of mineral matter anti-explosion cable.
Background technology
Power cable is the cable for transmitting and distribute electric energy, and power cable is usually used in Urban Underground electrical network, power station lead line, industrial and mining enterprises' in-line power and power transmission line under crossing river seawater.In power circuit, cable proportion increases just gradually.Power cable is the cable product in order to transmission and distribution high-power power in the basic routing line of electric power system, comprises 1-500KV and above various electric pressure, the power cable of various insulation.In can being divided into by electric pressure, lv power cable (35 kilovolts and following), high-tension cable (more than 110 kilovolts), extra-high-tension cable (275 ~ 800 kilovolts) and extra-high-tension cable (1000 kilovolts and more than).In addition, also ac cable and direct current cables can be divided into by electric current system.The basic structure of power cable is made up of core (conductor), insulating barrier, screen and protective layer four part.At present, it is poor that existing power cable ubiquity fire protecting performance, the problems such as flexibility is low, and explosion-proof performance is undesirable.
Utility model content
The utility model is intended to overcome the deficiencies in the prior art part and provides a kind of structure simple, and fire protecting performance is good, and flexibility is high, the mineral matter anti-explosion cable that explosion-proof performance is desirable.
For solving the problems of the technologies described above, the utility model realizes like this.
A kind of mineral matter anti-explosion cable, it comprises conductor thread core, conductor shield, insulating barrier, insulation screen, ceramic silica gel screen, fireproof material layer, aluminum alloy strip interlocking armour and external sheath layer; Described conductor shield is coated on conductor thread core; Described insulating barrier is coated on conductor shield; Described insulation screen is coated on insulating barrier; Described ceramic silica gel screen is coated on insulation screen; Described aluminum alloy strip interlocking armour is coated on fireproof material layer; Described external sheath layer is coated on aluminum alloy strip interlocking armour.
As a kind of preferred version, the thickness of ceramic silica gel screen described in the utility model is 0.03 ~ 0.08mm.
The insulating barrier of power cable is made up of various combustibles such as paper, oil, fiber crops, rubber, plastics, pitches, and therefore, cable has the possibility of blast on fire.The utility model structure is simple, and fire protecting performance is good, and flexibility is high, and explosion-proof performance is desirable, and long service life, has good electric property, applied widely.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Protection range of the present utility model is not only confined to the statement of following content.
Fig. 1 is the utility model structural representation.
In figure: 1, conductor thread core; 2, conductor shield; 3, insulating barrier; 4, insulation screen; 5, ceramic silica gel screen; 6, fireproof material layer; 7, aluminum alloy strip interlocking armour; 8, external sheath layer.
Embodiment
As shown in the figure, mineral matter anti-explosion cable, it comprises conductor thread core 1, conductor shield 2, insulating barrier 3, insulation screen 4, ceramic silica gel screen 5, fireproof material layer 6, aluminum alloy strip interlocking armour 7 and external sheath layer 8; Described conductor shield 2 is coated on conductor thread core 1; Described insulating barrier 3 is coated on conductor shield 2; Described insulation screen 4 is coated on insulating barrier 3; Described ceramic silica gel screen 5 is coated on insulation screen 4; Described aluminum alloy strip interlocking armour 7 is coated on fireproof material layer 6; Described external sheath layer 8 is coated on aluminum alloy strip interlocking armour 7.The thickness of ceramic silica gel screen 5 described in the utility model is 0.05mm.
The effect of the screen of power cable generally divides two kinds: the current ratio that (1) is passed through because of power cable is comparatively large, can produce magnetic field around electric current, in order to not affect other element, and can this electromagnetic-field-shielded in cable so add screen; (2) can play certain ground protection effect, if occur damaged in cable core, the electric current leaked along shielding laminar flow as ground network, can play the effect of safeguard protection.
The material of main part of Ceramic silicon rubber is heat vulcanized silicone rubber, possesses the fundamental characteristics of silicon rubber at normal temperatures.Silicon rubber gathers the characteristic that the electric wire, the cable that add auxiliary agent and make still possess silicon rubber under normal conditions; under 500 degree of high temperature even flame ablation of more than 700 degree; silicon rubber forms hard ceramic protective layer; thus play isolated flame, fireproof effect, ensure that in case of fire electric power, communication unimpeded.Ceramic silicon rubber is in HTV raw-silastic continuously, adds white carbon, silicone oil, antistructurizing agent and other auxiliary agent, mixing through vacuum kneader, adds vulcanizing agent on a mill until and makes.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
