Description
Technical field
The utility model relates to a kind of electric wire, particularly relates to a kind ofly to have vibration resistance, the fire-resistant wires of water-fast spray function and fire-resisting cable.
Background technology
The polyolefin jacket that tradition fire-resistant wires (comparative example 1) generally comprises conductor, is wrapped in the mica belt of conductor and is squeezed on mica layer.The fire-resistant vibration experiment that above-mentioned fire-resistant wires carries out in Europe superscript BS6387 and GB GB/T 19216 is tested and standard refractory Water spray experiment test.
Fire-resistant vibration experiment test: sample 1.5 meters of single core cables many (such as 5), by two ends peeling 10mm, wire rod is twisted into a branch of, be bundled on a rectangular steel plate, binding shape is Z-shaped, then two ends conductor is connected corresponding power supply and indicator light, separately with the iron staff of long 600mm, according to the time arranged, steel plate is regularly knocked during operation, knock direction and level forms 60 degree of angles.After test starting, be 750V by voltage sets, flame temperature is set as 900 ± 50 degree, burn 120 minutes, the time of knocking is set at interval of within 5 minutes, knocking once (or adopt flame temperature to be set as 900 ± 50 degree, burn 30 minutes, the time of knocking is set to knocked once at interval of 15 seconds), indicator light without any an extinguishing, can confirm that experiment is qualified during this test run.(note: indicator light extinguishes, illustrates that circuit is short-circuited phenomenon, and fireprotection layer could not available protecting circuit, test crash).
Spray test: with reference to the experiment of BS6387 standard refractory Water spray, formulate test sample, connect power supply and indicator light, after installing, starting test, is 750V by voltage sets, flame temperature is set as 650 ± 40 degree, the sustained combustion again add Water spray 15 minutes of burning after 15 minutes.Indicator light without any an extinguishing, can confirm that experiment is qualified during this test run.
By above-mentioned fire-resistant wires according to the fire-resistant vibration experiment test in Europe superscript BS6387 and GB GB/T 19216 and standard refractory Water spray experiment test, repeatedly test result shows: the fire-resistant wires that above-mentioned employing mica tape is wound around can pass through above-mentioned two tests sometimes, sometimes above-mentioned two tests can not be passed through, research staff is through repeatedly testing and carrying out technical Analysis, find that this is because mica tape in use needs to be wrapped on conductor, in winding process, due to the defect that mica itself is easily crisp, bending is wound around frangible cracking, less stable, bad during product fashion, can not guarantee that fire-resistant wires can by above-mentioned test, its consistency is unstable.
Research staff is through constantly research and development, and improvement opportunity scheme, Ceramics SiClx rubber substitutes mica tape and is wound around (comparative example 2), namely on conductor, extrudes Ceramic silicon rubber, then at the additional polyolefin jacket of Ceramic silicon rubber layer.By this kind of fire-resistant wires equally according to the fire-resistant vibration experiment test in Europe superscript BS6387 and GB GB/T 19216 and standard refractory Water spray experiment test, find to be difficult to equally by above-mentioned two kinds of tests.Because Ceramic silicon rubber burns to a crisp into porcelain in combustion, if product is in test process, there is bending place, then stressed meeting is larger herein, meanwhile, because Ceramic silicon rubber material expansion coefficient is comparatively large, inconsistent with the copper conductor coefficient of expansion, the extruding force that mutually expands is formed under the state of heat, when comprehensive above two kinds of power, when additional vibration force, material is more easy to crack in bending place, produce mutual short circuit phenomenon, product test is defective.
