Abstract
The present utility model discloses a ceramic silicone rubber insulation fireproof cable. The cable comprises a cable core which is formed by stranding a plurality of insulation wire cores, flame-retarding fills are filled in a gap inside the cable core, an armor layer is extruded outside the cable core, and an over sheath is extruded outside an outermost layer. Each insulation wire core is composed of a middle conductor and a ceramic silicone rubber insulation layer wrapped outside the conductor. Large-length and large-specification production is realized, products are soft, installing and laying are convenient, the number of middle joints is small, and performance standards and requirements of a mineral insulation cable can be completed satisfied.
Description
Technical field
The utility model belongs to the power cable field, specifically a kind of ceramic silicon rubber insulation fireproof cable.
Background technology
Use in the market more fireproof cable to be mineral insulated cable.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 and use also have nearly more than 20 years history, and are 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 larger, is difficult for carrying out bending during construction, so no matter from reducing cost or construction technology aspect, all necessarily require the length of ordering goods quite accurate.Simultaneously, because the cross-section of cable is long-pending greater than 25mm
2Can only produce single core, and cable length is limited by maximum delivery length, 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 close to 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 larger, causes economic benefit not good.
The utility model content
Technical problem to be solved in the utility model provides that a kind of fireproof＝fire-proof is good, good bandability, anticorrosive property is good, mounting and installation is convenient, the ceramic silicon rubber insulation fireproof cable of the low greatly specification production of cost.
A kind of ceramic silicon rubber insulation fireproof cable described in the utility model comprises cable core, and its cable core is by stranded the forming of some eradication edge cores, and fire-retardant filling is filled at the place in the cable core internal pore, extrudes armour outside cable core, and outermost layer extrudes oversheath.
Described insulated wire cores is by conductor and be coated on the outer insulating barrier of conductor and form.
The beneficial effects of the utility model are:
The utility model adopts ceramic 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; duricrust not melting under fire (650-1300 ℃) environment; do not drip; ensured that circuit is unimpeded in the situation of fire, played firm protective effect.It can overcome the weakness of existing mineral insulated cable, realizes big-length, large specification production, and product is soft, and mounting and installation is convenient, 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 structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of ceramic silicon rubber insulation fireproof cable described in the utility model, comprise cable core, its cable core is by stranded the forming of some eradication edge cores, fill fire-retardant filling 3 at cable core internal pore place, extrude armour 4 outside cable core, outermost layer extrudes the plastic material oversheath 5 of LSZH.Described insulated wire cores is by conductor 1 and be coated on the outer ceramic silicone rubber insulation layer 2 of conductor 1 and form.
Raw material selection of the present utility model and production technology:
1) cable conductor:
To opposite stranded the forming of stranded conductor structure, its stranded rear external diameter approaches by strand copper wire 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 chemoprevention fire silicon rubber, be a kind of novel polymer composite, behind over cure, possessed at normal temperatures high temperature resistant, anti-aging, the good characteristics such as electrical property of ordinary silicon rubber wire cable; Characteristics with fire-retardant, Halogen, low cigarette, non-corrosiveness and toxicant and γ-ray emission during burning can not cause secondary harm to disaster-stricken people; By the hard housing of forming after burning, can bear certain water spray and the vibrations of some strength, can guarantee that circuit does not rupture, not short circuit is for fire protection provides necessary prerequisite guarantee.

3) outer jacket:
Outer protective sleeve adopts the plastic material of LSZH, and good anti-corrosion property is arranged.Copper strip shielding is arranged in the sheath, and its copper strip shielding is again good conductor, is best earth connection, and arrives continuously the cable total length, has greatly improved ground protection sensitivity and reliability.
The utility model provides a kind of thinking and implementation method of ceramic silicon rubber insulation fireproof cable; concrete application approach is a lot; the above only is preferred implementation 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.
