Fampisehoana tsara amin’ny kasety mika

As the main raw material of fire-resistant cables, mica tape should have its product standards. The technical conditions for the specified performance indicators and test methods of mica tape products fully reflect the objective and practical needs. It is necessary for the electrical performance of mica tape to be assessed at the same time by the two indicators of insulation resistance value and withstand voltage at high temperature. Due to the large variety of fire-resistant cables, the entire insulation system (including conductor-to-conductor and conductor-to-shielding systems) ) There are certain requirements. When the insulation resistance drops to a certain value, even if there is no insulation breakdown, the entire circuit system will lose its normal operation function. For the quality of fire-resistant cables, the quality of mica tape is the key to its “fire-resistant” function.

Ny kasety mica dia manana fanoherana ny hafanana avo lenta sy fanoherana ny fandoroana. Ny fantsom-pitaovana mikarasy dia manana fifehezana tsara amin’ny toe-javatra mahazatra ary mety amin’ny sosona fanamafisana tsy misy afo amin’ny tariby sy tariby mahazaka afo. Koa satria ny mica tape dia mampiasa loko adhesive silika biolojika miaraka amina fahombiazana tsara toy ny adhesive, amin’ny ankapobeny tsy misy volatilization setroka manimba rehefa dorana amin’ny lelafo misokatra. Noho izany, ny mika tape dia tsy mahomby amin’ny tariby sy tariby mahazaka afo ihany, fa azo antoka koa.

mica tape dia afaka mamaly ny sasany amin’ireo fepetra takiana amin’ny motera avo lenta, noho izany dia be mpampiasa. Miaraka amin’ny fitomboan’ny haavon’ny angovo môtô, ny fanatsarana tsy tapaka ny fahaiza-manao sy ny fivoaran’ny fahombiazana mitohy, ny fepetra takiana amin’ny insulation ny motera dia nohatsaraina tsy tapaka ihany koa, ary eo am-panombohana ihany koa ny fikarohana momba ireo fitaovana insulation mifanaraka amin’izany. Ny kasika mika dia vita amin’ny taratasy mika ho akora mahazatra, ary ny lafiny roa na ny lafiny iray dia samy vita amin’ny lamba fitaratra tsy misy alika elektrika sy sarimihetsika polyester na sarimihetsika polyimide na horonantsary mahatohitra korona ho fitaovana manamafy amin’ny alàlan’ny dingana manokana . Miorina amin’ny firafitra, mizara ho: kasety roa-lafiny, kasety tokana, kasety telo-iray, kasety horonan-tsary roa, kasety sarimihetsika tokana, sns. , kasety phlogopite, ary kasety muscovite.

Ny afo dia mety hitranga na aiza na aiza, fa rehefa misy afo mitranga amin’ny toerana misy mponina marobe ary takiana amin’ny fiarovana avo lenta dia ilaina tokoa ny miantoka fa ny herinaratra sy ny tariby fampahalalana dia mitazona fandidiana mahazatra mandritra ny fotoana ampy, raha tsy izany dia mitera-doza lehibe izany. Noho izany, ny tariby tsy mirehitra vokarina amin’ny kasika mika dia be mpampiasa amin’ireto toerana manaraka ireto: sehatra fandavahana solika, tranobe avo, tobin-jiro lehibe, metro ary orinasa lehibe indostrialy sy harena ankibon’ny tany mifandraika amin’ny fiarovana ny afo sy ny famonjena afo. Ny kasety Mica dia manana fahombiazana tena tsara sy fampiasana mety ary nanjary fitaovana ho an’ny tariby mahazaka afo.
