Accompanying drawing explanation
Fig. 1 is structural representation of the present invention,
Wherein: 1, twisted copper conductors; 2, quality refractory mica tape insulating barrier; 3, alkali-free glass wool packed layer; 4, alkali-free glass wool twining package tape; 5, embossing copper sheath; 6, refractory ceramic SiClx rubber outer protection cover.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described;
As shown in Figure 1, a kind of soft level mineral insulated cable, it is by conductor wire core, quality refractory mica tape insulating barrier 2, alkali-free glass wool packed layer 3, alkali-free glass wool twining package tape 4, embossing copper sheath 5 and refractory ceramic SiClx rubber outer protection cover 6 composition, described conductor wire core is formed by the coated twisted copper conductors 1 of quality refractory mica tape insulating barrier 2, the coated alkali-free glass wool twining package tape 4 in outside of described quality refractory mica tape insulating barrier 2, alkali-free glass wool packed layer 3 is provided with between described quality refractory mica tape insulating barrier 2 and wrapped 4 bands of alkali-free glass wool, the coated embossing copper sheath 5 in outside of described alkali-free glass wool twining package tape 4, described embossing copper sheath 5 is coated with refractory ceramic SiClx rubber outer protection cover 6.
The number of described conductor wire core is one or more.
Described conductor wire core is made up of the twisted copper conductors 1 of some layers, and every layer of twisted copper conductors 1 is formed with prismatic conductor strand by some stocks, and per share conductor is made up of some conductor monofilament, and direction of lay is between layers contrary.
The cross section of described conductor wire core is circular.
Described quality refractory mica tape insulating barrier 2 adopts fire resistance and the superior mica wrapping tape of insulation property to be material.
Every root conductor monofilament of described conductor wire core is circular copper wire or overlay coating is the single round copper wire of tin.
Cable inner core can have that more than one conductor wire core is stranded to be formed, also can there be two, three, four, five or more conductor wire core is stranded and make, the geometry of the one-tenth cable core be made up of multiple same uiform section conductor wire core is circular, geometry is fixed, stability is high, on cable can curvature impact very little.The surperficial wrinkle that do not have of single round copper wire, crackle, burr, field trash and other defect harmful to use.Single line allows welding, but the distance between adjacent two solder joints should be not less than 300mm, and welding is wanted firmly, and smoothing cavetto is wanted in joint.Variously whole root bead is not allowed to connect through stranded core.In cable inner core gap, be provided with alkali-free glass fibre packed layer 3, there is high temperature resistant, flame resistant, not Halogen, the nonflammable feature such as to be fuming.The positive and negative two-layer alkali-free glass wool twining package tape 4 of tight wrapped bundle outside again, the rate of putting up is not less than 45%, in case bonding and affect the machinery, physics, electrical property etc. of cable between phase alternating layers, can also strengthen tension and the stressed degree of resist bending of cable.This kind of alkali-free glass wool twining package tape 4 and alkali-free glass fibre packed layer 3 adopt aluminium borosilicate glass to take out fibrage processed and form; its alkaline metal cpds is not more than 0.5%; directly band shape is made after finished product; band lock seaming, not frangibility, performance softness, wrapped smooth, stretching resistance extra-heavy, after meeting naked light, can not burn temperature less than 900 DEG C; flame can be stoped to pass; protection insulating barrier is not burned, and the smog discharged during burning is few, greatly reduces fire evil degree.When cable runs into burning; alkali-free glass wool twining package tape 4 and alkali-free glass fibre packed layer 3 can attract a large amount of heats; and form the shell isolated air of carbon; hinder the supply of oxygen and the flowing of fuel gas; protection insulating barrier is from burning; prevent cable from burning further, make the loss of fire be unlikely further extension.Embossing copper sheath 5 should adopt and be not less than the TU level oxygen-free copper stripe or T2 level copper strips material that GB/T5231 specifies, and adopts argon arc welding to weld commissure, and weld intensity should be not less than 80% of mother metal.Under high temperature more than 500 DEG C and flame ablation, organic principle ablatedly in a short period of time can change into hard ceramic-like material, form the isolation layer that one deck is good, stop burning away of flame, and the ablation time is longer, temperature is higher, and hard effect is more obvious, can reach 1200 ~ 1500 DEG C and not dissolve.Remained without any ashes by after burning simultaneously.For fire-fighting, fire prevention provide novel, safety, an economic fireproof cable, the especially manufacture of fireproof electric wire and cable, hew out again new approaches and new method, its birth makes the production and processing of fireproof cable, laying installation and application obtain further simplification, compare with mineral insulation magnesium oxide fireproof cable, cost is significantly reduced, for universal and popularization provides reliable guarantee widely.
Although give detailed description and explanation to the specific embodiment of the present invention above; but what should indicate is; we can carry out various equivalence according to conception of the present invention to above-mentioned execution mode and change and amendment; its function produced do not exceed that specification contains yet spiritual time, all should within protection scope of the present invention.
