PVA cable: Iimpawu kunye Izicelo

PVA cable a ucingo lobhedu bhetyebhetye, injongo esebenzayo edla umzi. Ukwakhiwa kwayo waphila - balahleke. Inzuzo ephambili yale intambo ezahlukeneyo, xa kuthelekiswa nabanye, ukuba bhetyebhetye yalo phezulu. Ngokukodwa, ngokomlinganiselo wesizwe, ngokwendlela le mithambo laka eyabelwe kwiklasi yesihlanu. Ngenxa iqondo eliphezulu ukumelana nazo zonke iintlobo uxinezeleko ngoomatshini kunye deformation, ngesalathisi enjalo ingachazwa kuhle kakhulu.

PVA cable uye layers yokugquma ezimbini: lwangaphandle nangaphakathi. Xa indima izinto zeplastiki PVC isebenza ukuba bazivelise okanye bazenze. Baya ziyahluka ukusuka omnye komnye umbala wabo kunye neempawu zejometri. Ngamnye kule umphakathi ijijekileyo kwi uwele kwaye kukho ukhuseleko owongezelelweyo ngohlobo PVC maleko ubhityileyo. Njengoko ngenxa yokugquma zangaphandle, ngoko wazalisa imigodi phakathi abaqhubi. ixabiso layo kubalulekile, ukongeza, ukuba ukunika imilo setyhula. Yiyo le sakhiwo imisela iimpawu eziphambili ngomatshini, nto leyo ndoqhayisa PVA intambo. Umaleko engaphandle ixesha elide PVC ezingundoqo awukhusele umonakalo deformation, kunye nokusetyenziswa ubhedu iqinisekisa iqondo eliphezulu namandla.

Yeqokobhe nganye umphakathi uye umbala yayo. imibala ezingundoqo oluhlaza, omdaka, otyheli kunye eluhlaza, emnyama kunye nobomvu. Oku kwenziwa ukuze kuqinisekiswe ukuthotyelwa kunye nemigangatho yamazwe ngamazwe, nto leyo ezibekwe ukubonisa zero nesigaba iingcingo ngqo. Kufuneka kuqatshelwe inkalo ebalulekileyo yokugquma USB, esakhiwa ngo isibakala ukuba nelangatye nekudodobalisa.

Izicelo key

Amaxesha amaninzi, intambo PVA isetyenziswa ngokudibanisa ezahlukeneyo eziphathwayo ukuba inokufana izixhobo ikhaya encinane, aqokele izixhobo ezinamandla - izixhobo zoshishino okanye sixhobo. Oku kungenxa yokuba i-wire enoluhlu kunokuba ebanzi cross-amacandelo, leyo uluhlu milimitha square ukusuka 0.75 ukuya 16. Kufuneka kuqatshelwe ukuba ngamnye kubo wenza intambo kokuba ezimbini, ezintathu, ezine okanye ezintlanu waphila. It ikuvumela ukuba ukwazi ukuqhagamshela aze oononye-kwesigaba ezintathu ombane isigaba. Esi sicelo kule kholam ayiphelelanga ulwandiso enye kuphela. PVA cable isoloko isetyenziswa ngohlobo ingcingo lwangaphakathi kunye nokufakwa ngemixokelelwane mveliso, zasekhaya kunye etyholweni phakathi, nangona kubonakala ukuba ndlela elula kakhulu ngenxa yale njongo. Into engundoqo ke ukuba ukulibala ukuba umphakathi ngexesha lofakelo kunyanzelekile ukuba ufake kwi kwiitheminali ehambelana okanye uvavanyo uxinzelelo esebenzisa lugs intambo.

iimeko lobushushu

PVA USB, iimpawu eziye ichazwe ngasentla, yenziwa ngo lunee ezintathu kuthelekiswa lobushushu. Ukumakishwa "Y" libonisa ukuba uvumelekile ukuba asebenzise xa ubushushu ebonisa 40 Celsius ukuya kutsho kuma-40 Celsius. Kuzo zonke ezinye iimeko kufuneka ukuba amaqondo obushushu ungabi ngaphantsi kwe 25 Degrees. Njengoko ubomi ugesi, oko kukuthi iminyaka engama-6, kunye nokusebenza ngayo iimeko zokubhala - 10 iminyaka.
