Bl-iżvilupp tax-xjenza u t-teknoloġija, il-kwalità ta 'diversi proġetti ta' kostruzzjoni qed titjieb gradwalment. Min-naħa waħda, hija l-applikazzjoni ta 'teknoloġija avvanzata ta' inġinerija, u min-naħa l-oħra, tibbenefika mill-użu dejjem jikber ta 'materjali ta' inġinerija ta 'teknoloġija għolja fl-inġinerija. The application of MICC cable has provided great help for the quality improvement of construction projects. Kejbils iżolati minerali, bil-karatteristiċi eċċellenti tagħhom ta 'reżistenza għan-nar, reżistenza għall-umdità, u reżistenza għas-sħana, jiżguraw ħafna s-sigurtà tal-bini.
The reason why mineral-insulated cables have these characteristics is closely related to their unique structure and materials. Bhalissa, there is not only one type of mineral-insulated power cable on the market. In addition to the commonly used BTTZ MICC cable, a variety of flexible mineral-insulated power cables have emerged in recent years. Il-wieħed rappreżentattiv huwa l-kejbil iżolat minerali tat-tip YTW, it-tnejn li huma għandhom karatteristiċi komuni. Madankollu, there are differences in performance, għalhekk l-effetti attwali tal-applikazzjoni tat-tnejn mhumiex l-istess, u jistgħu jiġu ttrattati b'mod differenti f'applikazzjonijiet speċifiċi ta 'kostruzzjoni.
MICC Cables from ZMS Cable Manufacturer
ZMS produces high-quality mineral insulated cables, with a copper sheath wrapped around the copper conductor core, and magnesium oxide powder as the inorganic insulating material to isolate the conductor and the sheath of the cable. That is to say, the magnesium oxide insulation layer is between the core conductor and the copper sheath, and the outermost layer can be selected according to the need for an appropriate outer sheath.
There is a similar cable with a metal sheath instead of a copper sheath covering the conductor core and magnesium oxide insulation, called mineral insulated metal sheathed cable.
Classification and Application of MICC Cables
Because the structure of mineral insulated cables is unique, and the materials used have inorganic insulating properties, meta mqabbla ma 'kejbils ordinarji ritardanti tal-fjammi u reżistenti għan-nar, għandhom reżistenza tajba għan-nar, reżistenza taż-żejt, high-temperature resistance, reżistenza għall-korrużjoni, and other properties, u l-piż tagħhom huwa relattivament għoli.
Il-kejbils iżolati minerali attwali huma prinċipalment maqsuma f'żewġ kategoriji, wieħed huwa l-kejbils minerali li jifilħu n-nar tradizzjonali, namely BTTZ type mineral insulated power cables. The other is a flexible mineral insulated wire that has been emerging in recent years and has been well-used, jiġifieri kejbil iżolat minerali tat-tip YTTW. The traditional mineral fireproof cable is insulated with magnesium oxide powder. This kind of MICC cable has been used for a long time. Our country has used this kind of mineral-insulated cable for nearly 30 snin. Il-proprjetajiet mekkaniċi tiegħu huma relattivament tajbin, iżda r-rekwiżiti tat-tqegħid huma relattivament għoljin. Ir-rekwiżiti tal-proċess tal-installazzjoni tal-kejbil huma relattivament għoljin, u l-ispazju okkupat huwa relattivament kbir. Ġeneralment użat fi proġetti ta 'kostruzzjoni partikolarment importanti, bħal bini pubbliku super high-rise, bini kummerċjali kbir ħafna, eċċ.
The flexible mineral insulated cable is a mineral insulated power wire that uses glass fiber and mica composite materials as insulation. Huwa aktar konvenjenti li jintuża u jista 'jintuża f'bini residenzjali super high-rise u bini kummerċjali importanti ieħor fuq skala kbira u proġetti ta' kostruzzjoni kumplessi.
Selected the Length of Mineral Insulation Cables
When carrying out the construction of mineral-insulated cables, special attention should be paid to the length of the mineral-insulated cables, because the MICC power wires are customized by the cable manufacturer skond l-ispeċifikazzjonijiet meħtieġa, u t-tul tagħhom ma jistax jintgħażel b'mod arbitrarju. Fil-kostruzzjoni, there is often a phenomenon that the delivery length of mineral-insulated cables is not considered carefully. Jew hemm sitwazzjoni fejn il-konnessjoni ssir fin-nofs tal-kejbil, li taffettwa l-effiċjenza tal-kejbil. Għalhekk, qabel il-kostruzzjoni, huwa meħtieġ li titqabbel is-sitwazzjoni tas-sit tal-kostruzzjoni fid-dettall, tiddetermina l-post tal-kejbil tal-installazzjoni, u kkalkula bir-reqqa t-tul tal-kejbil meħtieġ. Fl-akkwist tal-kejbil attwali, huwa dwar 1% aktar mit-tul ikkalkulat. Biex jiġi evitat il-fenomenu ta 'tul insuffiċjenti tal-kejbil waqt il-kostruzzjoni.
