Muaj ib hom kev nkhaus uas siv dav, uas yog lub helix. Lo lus kauv los ntawm Greek thiab nws lub ntsiab lus tseem ceeb yog "coiling" lossis "entangling".
Ntau tshaj 2000 xyoo dhau los, tus kws lej Greek thaum ub Archimedes tau tshawb fawb txog cov kab kauv. Tus naas ej lej Descartes thawj zaug piav txog lub logarithmic helix nyob rau hauv 1638 thiab teev cov mis analytical rau lub helix. Cov kauv no muaj ntau yam ntxwv, thiab qhov tseem ceeb tshaj plaws yog nws cov duab. Txawm hais tias koj loj lossis ntsws, nws yuav tsis hloov, ib yam li peb tsis tuaj yeem nthuav lub kaum sab xis.
Yuav luag tag nrho cov kev lag luam xav tau kev siv cov kauv cables. Txawm nyob rau hauv kev sib txuas lus (xov tooj, xov tooj cua), kev kho mob technology, hluav taws xob locomotive kev lag luam, mechanical engineering, los yog teeb pom kev lag luam, kauv cables yog siv nyob rau hauv txhua qhov chaw. Ntxiv nrog rau nws cov khoom siv hluav taws xob zoo, cov kav hlau txuas feem ntau yog siv los ua cov kev daws teeb meem zoo tshaj plaws.
Yog tias koj siv PVC thiab PUR cables, cov xim ntawm cov kauv cable feem ntau tuaj yeem koom tes nrog cov xim ntawm cov khoom. Peb tseem tuaj yeem muab cov hlua khi hlua khi. Kauv caij nplooj ntoos hlav cable series, kauv cables rau cov twj paj nruag thiab meters, caij nplooj ntoos hlav xov hlau rau automotive fais fab mov, kauv cables rau transformer fais fab mov, kauv cables rau loj electromechanical khoom, kauv cables rau tu tshuab fais fab mov, 5-core caij nplooj ntoos hlav xov hlau rau tsis siv neeg nqi hluav taws xob meters, thiab lwm yam.
