Intambo inokumelana namandla angaphandle kunye neemeko zokusingqongileyo ezinxulumene nokufakelwa okunjalo, ukuqinisekisa ukusebenza kwexesha elide.
III. Iimpawu
I-Voltage elinganisiweyo
Ngombane olinganisiweyo we-Uo/U: 300/500V, intambo iyakwazi ukusebenza ngaphakathi kolu luhlu lwevolthi, ibonelela ngombane othembekileyo kwiisignali ezidlulisiweyo. Olu vavanyo lwevolthi lufanelekile kwiindlela ezininzi zonxibelelwano kunye nezicelo zolawulo.
Ubushushu obulinganisiweyo
Intambo inomlinganiselo wobushushu olinganisiweyo ohluka ngokuxhomekeke kwimeko yayo. Kwiindawo ezimiselweyo, inokunyamezela ubushushu ukusuka kwi - 40ºC ukuya kwi +80ºC. Xa iguquguquka, uluhlu lobushushu luqala kwi 0ºC ukuya kwi +50ºC. Olu tshintsho lubanzi lobushushu luyenza ikwazi ukusetyenziswa kwiindawo ezibandayo nezishushu, nto leyo eyenza ukuba ikwazi ukuguquguquka kakhulu.
Ubuncinane beRediyasi yokugoba
Ekubeni i-radius yokugoba incinci ye-12D, intambo inokugoba ukuya kuthi ga kwinqanaba elithile ngexesha lokufakwa ngaphandle kokubangela umonakalo kwisakhiwo sayo sangaphakathi. Oku kuguquguquka kokugoba kubalulekile ekuhambiseni intambo kwiisetingi ezahlukeneyo zofakelo.
IV. Ulwakhiwo
Umqhubi
Kwiindawo ezinqamlezileyo eziphakathi kwe-0.5mm² - 0.75mm², intambo isebenzisa ii-conductors ze-copper eziguquguqukayo zeClass 5. Ezi conductors zibonelela ngokuguquguquka okuphezulu, okuluncedo kwizicelo apho kufuneka intshukumo ethile okanye ukuguquguquka kwintambo. Kwiindawo ze-1mm² nangaphezulu, kusetyenziswa ii-conductors ze-copper ezifakwe kwi-stranded zeClass 2. Zibonelela ngokuhambisa kakuhle kunye namandla oomatshini, ziqinisekisa ukuhanjiswa kwesignali ngokufanelekileyo kunye nokuqina.
Ukuvala ubushushu
Kusetyenziswa i-insulation ye-XLPE (Cross-Linked Polyethylene), eneempawu ezintle kakhulu zokukhusela umbane. Inceda ekuthinteleni ukuvuza kombane kwaye iqinisekisa ukuba imiqondiso idluliselwa ngokufanelekileyo ngaphandle kokuphazamiseka.
Uvavanyo
Isikrini esipheleleyo esenziwe nge-Al/PET (Aluminium/Polyester Tape) sikhusela ukuphazamiseka kwe-electromagnetic. Oku kubalulekile ekugcineni ukuthembeka kwemiqondiso edluliselweyo, ingakumbi kwiindawo apho kunokubakho imithombo ye-electromagnetic yangaphandle.
Ucingo lokukhupha amanzi
Ucingo lokukhupha ubhedu olufakwe kwisitya lunceda ekususeni naziphi na iitshaja ze-electrostatic ezinokuqokelelana kwintambo. Oku kunceda ekuphuculeni ukhuseleko kunye nokusebenza kwentambo.
Ijakethi yangaphakathi
Ijakethi yangaphakathi eyenziwe ngezinto ze-LSZH (Low Smoke Zero Halogen) luphawu olubalulekileyo lokhuseleko. Kwimeko yomlilo, ayizukukhupha umsi omninzi okanye iihalogen ezinetyhefu, nto leyo ekhusela okusingqongileyo nezixhobo ezingqongileyo.
Isikrweqe
I-SWA (Galvanised Steel Wire Armour) inika ukhuseleko oluqinileyo loomatshini. Iyakwazi ukumelana namandla angaphandle anjengokutyumza, ukubetheka, kunye nokukrazuka, ikhusela izinto zangaphakathi zentambo.
Isingxobo
I-sheath yangaphandle yenziwe ngezinto ze-LSZH (Low Smoke Zero Halogen), nto leyo ephucula ngakumbi iimpawu zokhuseleko lwe-cable. Umbala we-sheath oluhlaza okwesibhakabhaka ukuya kumnyama unceda ekuchongeni i-cable ngokulula kwindawo enzima yokufaka.
Ukuqukumbela, intambo ye-BS 5308 Part 1 Type 2 PE/IS/OS/PE/SWA/PVC yintambo eyilwe kakuhle edibanisa iimpawu zombane, zoomatshini, nezokhuseleko ezifunekayo kwiintlobo ngeentlobo zezicelo. Amandla ayo okudlulisa iintlobo ezahlukeneyo zemiqondiso, kunye nokuzivumelanisa kwayo neemeko ezahlukeneyo zendalo, yenza ukuba ibe lukhetho oluthembekileyo kumashishini afana neshishini le-petrochemical kunye nezinye izicelo apho unxibelelwano kunye nokuhanjiswa kwesignali yokulawula kubalulekile.
