Zingwe zoyankhulirana zotsika pafupipafupi komanso zotsika pang'ono nthawi zambiri zimapangidwa ndi polyethylene yokhala ndi thovu kapena thovu la polypropylene ngati insulating, mawaya awiri otsekera pachimake ndi waya pansi (msika wapano ulinso ndi opanga omwe amagwiritsa ntchito magawo awiri awiri) mu makina omata, kukulunga zojambulazo za aluminiyamu ndi mphira. tepi ya poliyesitala yozungulira waya wotsekera pachimake ndi waya pansi, kapangidwe kake kakutchinjiriza ndikuwongolera njira, kapangidwe ka mzere wothamanga kwambiri, zofunikira zamagetsi zamagetsi ndi chiphunzitso chotumizira.
Zofunikira za conductor
Kwa SAS, yomwe ilinso mzere wothamanga kwambiri, kufanana kwapangidwe kwa gawo lililonse ndilofunika kwambiri pozindikira mafupipafupi a chingwe.Choncho, monga woyendetsa maulendo apamwamba kwambiri, pamwamba pake ndi ozungulira komanso osalala, ndipo mawonekedwe a mkati mwa lattice ndi ofanana komanso osasunthika kuti atsimikizire kuti magetsi amafanana ndi kutalika kwake;Kondakitala ayeneranso kukhala ndi kukana kwa DC kochepa;Pa nthawi yomweyo ayenera kupewa chifukwa mawaya, zida kapena zipangizo zina chifukwa cha mkati kondakitala kupindika nthawi kapena sanali nthawi kupinda kupinda, mapindikidwe ndi kuwonongeka, etc., mu mkulu-pafupipafupi kufala mzere, kondakitala kukana ndicho chachikulu kuchititsa chingwe. attenuation (magawo apamwamba-magawo oyambira gawo 01- magawo ochepetsera), pali njira ziwiri zochepetsera kukana kwa conductor: kuonjezera m'mimba mwake wa conductor, kusankha kwa zida zowongolera zotsika.Pambuyo pakuwonjezeka kwa kondakitala, kuti akwaniritse zofunikira za impedance, m'mimba mwake wakunja kwa kutchinjiriza ndi mainchesi akunja azinthu zomalizidwa zimachulukitsidwa molingana, zomwe zimapangitsa kuti ndalama ziwonjezeke komanso kukonza zovuta.Mwachidziwitso, pogwiritsa ntchito kondakitala wa siliva, m'mimba mwake wakunja kwa chinthu chomalizidwa chidzachepetsedwa, ndipo ntchitoyo idzasintha kwambiri, koma chifukwa mtengo wa siliva ndi wapamwamba kwambiri kuposa mtengo wamkuwa, mtengo wake ndi wokwera kwambiri kuti upangitse misa, kuti tiganizire mtengo ndi kutsika kwa resistivity, timagwiritsa ntchito khungu kuti tipange woyendetsa chingwe.Pakalipano, kugwiritsa ntchito ma conductors amkuwa a malata a SAS 6G amatha kukumana ndi magetsi, pomwe SAS 12G ndi 24G ayamba kugwiritsa ntchito ma conductor okhala ndi siliva.
Pakakhala malo osinthira apano kapena osinthira ma elekitikitimu mu kondakitala, kugawa komweko mkati mwa kondakitala kumakhala kosagwirizana.Pamene mtunda kuchokera kumtunda wa conductor ukuwonjezeka pang'onopang'ono, kuchuluka kwamakono mu conductor kumachepa kwambiri, ndiko kuti, panopa mu conductor idzakhazikika pamtunda wa conductor.Kuchokera panjira yodutsa ndege kupita kumayendedwe apano, mphamvu yapano yapakati pa kondakitala ndi zero, ndiye kuti, pafupifupi palibe mayendedwe apano, ndipo gawo lokhalo lomwe lili m'mphepete mwa kondakitala lidzakhala ndi ma subcurrents.Mwachidule, zamakono zimayikidwa mu gawo la "khungu" la conductor, choncho limatchedwa khungu.Chifukwa cha izi ndikuti kusintha kwamagetsi kwamagetsi kumapanga gawo lamagetsi la vortex mkati mwa kondakitala, lomwe limathetsedwa ndi choyambirira.Zotsatira za khungu zimapangitsa kukana kwa conductor kuwonjezereka ndi kuwonjezeka kwafupipafupi kwa kusinthasintha kwamakono, ndipo kumabweretsa kuchepetsa mphamvu ya kufalitsa mawaya panopa, kuwononga chuma chachitsulo, koma pakupanga zingwe zoyankhulirana zothamanga kwambiri, mfundoyi ikhoza kukhala. amagwiritsidwa ntchito kuchepetsa kugwiritsira ntchito zitsulo pogwiritsa ntchito plating ya siliva pamtunda pansi pa mfundo yokwaniritsa zofunikira zomwezo, potero kuchepetsa ndalama.
Zofunikira za insulation
Chimodzimodzinso ndi zofunikira za kondakitala, sing'anga yotsekereza iyeneranso kukhala yofananira, ndipo kuti mupeze ma dielectric otsika s ndi kutayika kwa dielectric Angle tangent value, zingwe za SAS nthawi zambiri zimagwiritsa ntchito kutchinjiriza thovu.Pamene digirii yotulutsa thovu ndi yayikulu kuposa 45%, kutulutsa thovu kwamankhwala kumakhala kovuta, ndipo digiri ya thovu ndi yosakhazikika, kotero chingwe chomwe chili pamwamba pa 12G chiyenera kugwiritsa ntchito kutchinjiriza kwa thovu.Monga tawonera pachithunzichi, pomwe thovu lili pamwamba pa 45%, gawo lakuchita thovu ndi kutulutsa thovu lamankhwala lomwe limawonedwa pansi pa maikulosikopu, ma pores omwe amatuluka thovu amakhala ocheperako, pomwe ma pores otulutsa thovu amakhala ocheperako:
