Abstract
The invention discloses a vitrified silicon rubber insulation fireproof cable which comprises a cable core, wherein the cable core is formed by stranding a plurality of insulation wire cores; a flame resistance filler is filled in a gap in the cable core; an armor layer is extruded on the cable core; and an outer sheath is extruded on the outermost layer. Each insulation wire core consists of a middle conductor and a vitrified silicon rubber insulation layer wrapping the conductor. Large-length and high-specification production is realized; a product is soft and convenient to assemble and lay; the number of middle joints is small; and the performance can completely meet the standard requirement of ore insulation cables.
Description
Technical field
The invention belongs to the power cable field, specifically is a kind of potteryization silicon rubber insulation fireproof cable.
Background technology
Use more fireproof cable to be mineral insulated cable in the market.The conductive copper wire core of traditional mineral insulated cable, copper oversheath and insulating barrier are closely knit one; External production and the existing nearly 80 years history of use; Domestic production also has nearly more than 20 years history with using, and widely-used in numerous large projects at home and abroad, and effect is excellent; But because mineral insulated cable production technology more complicated, price is more expensive, and hardness is bigger, is difficult for carrying out bending during construction, so no matter from the still construction technology aspect that reduces cost, the length that all necessarily requires to order goods is quite accurate.Simultaneously, because the cross-section of cable is long-pending greater than 25mm
2Can only produce single core; And cable length receives maximum delivery length restriction; It is also little real directly to order goods separately by every required cable length of scene; So must carry out rational permutation and combination to various model cables, make the length of every cable of order approach the maximum delivery length of producer, and just in time equal the length sum of some cables of on-the-spot actual needs.Because above and so on factor causes mineral insulated cable to be difficult for forming and produces in enormous quantities, installation difficulty is bigger, causes economic benefit not good.
Summary of the invention
Technical problem to be solved by this invention provides that a kind of fireproof property is good, good bandability, anticorrosive property are good, install lay conveniently, the pottery silicon rubber insulation fireproof cable of the low production of specification greatly of cost.
A kind of potteryization silicon rubber insulation fireproof cable of the present invention comprises cable core, and its cable core is by stranded the forming of some insulated cores, and fire-retardant filling is filled at the place in the cable core internal pore, outside cable core, extrudes armour, and outermost layer extrudes oversheath.
Said insulated wire cores is by conductor and be coated on the outer insulating barrier of conductor and form.
Described oversheath adopts the plastic material of LSZH.
Described insulating barrier adopts the potteryization silastic material.
Beneficial effect of the present invention is:
The present invention adopts potteryization silicon rubber as insulation; Have extraordinary fire prevention, fire-resistant, fire-retardant, low cigarette, nontoxic performance; Residue after its burning is the ceramic-like duricrust simultaneously, and duricrust not fusion under fire (650-1300 ℃) environment is not dripped; Ensured in the situation line of fire unimpededly, played firm protective effect.It can overcome the weakness of existing mineral insulated cable, realizes length, big specification production, and product is soft, installs and lays conveniently, and transition joint is less, and performance reaches the standard-required of mineral insulated cable fully.In addition, adopt the oversheath of the plastic material of LSZH, have good anti-corrosion property.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of potteryization silicon rubber insulation fireproof cable of the present invention comprises cable core; Its cable core is by stranded the forming of some insulated cores; Fill fire-retardant filling 3 at cable core internal pore place, outside cable core, extrude armour 4, outermost layer extrudes the plastic material oversheath 5 of LSZH.Said insulated wire cores is by conductor 1 and be coated on the outer pottery silicone rubber insulation layer 2 of conductor 1 and form.
Raw material selection of the present invention and production technology:
1) cable conductor:
To opposite stranded the forming of stranded conductor structure, its stranded back external diameter is approaching by multiply copper cash strand, and Haul Rate is identical, and strand is on the contrary, and therefore this structure can not produce in making and using and reverse, and has good flexural property.
2) insulating barrier:
Insulating material is the important component part of cable; Adopt high temperature resistant porcelain fireproof silicone rubber; Be a kind of novel polymer composite, behind over cure, possessed high temperature resistant, anti-aging, the good characteristics such as electrical property of ordinary silicon rubber wire cable at normal temperatures; Have the characteristics of fire-retardant, Halogen, low cigarette, non-corrosiveness and toxicant and gas produce during burning, can not cause secondary to endanger to the people that suffers from disaster; By the hard housing of forming after burning, can bear the certain water spray and the vibrations of certain intensity, can guarantee that circuit does not rupture, not short circuit is for the fire-fighting mitigation provides the necessary precondition guarantee.
