Comhlíontachtaí
Feidhmchlár
D’fhéadfaí sreang rialaithe armúrtha le scáileán fite a adhlacadh go díreach nuair a bhíonn trealamh rialaithe fadraoin ag teastáil, d’fhéadfadh sreang armúrtha an cábla a chosaint ó dhífhoirmiú comhbhrúite, agus d’fhéadfadh sreang fite an comhartha a choinneáil seasta.

An bhfuil a fhios agat an difríocht idir sreang rialaithe agus scáileán fite agus téip chopair?
Braitheann an t-idirdhealú idir cábla rialaithe sciatháilte le sreinge copair agus cábla rialaithe sciatháilte le téip chopair go príomha ar an éagsúlacht san ábhar agus sa struchtúr sciatháilte.
Tá an t-ábhar sciath comhdhéanta de: Is sreang chopair fhíodaithe ábhar sciath an chábla rialaithe sciathaithe fite sreinge copair, ach is téip chopair ábhar sciath an chábla rialaithe sciathaithe téip chopair.
Seo a leanas na difríochtaí struchtúracha idir an dá chineál cábla: Tá struchtúr sciath an chábla rialaithe sciath fite sreinge copair déanta suas de shreanga copair fite fuaite, ach tá struchtúr sciath an chábla rialaithe sciath téip chopair déanta suas de shraith amháin nó níos mó de théip chopair.
Tá difríocht idir feidhmíocht an dá chineál cábla ó thaobh solúbthachta agus inoiriúnaitheachta de. Ligeann braidáil sreinge copair solúbthacht agus inoiriúnaitheachta níos mó, rud a fhágann go bhfuil sé oiriúnach lena úsáid i gcásanna ina gcaithfidh an cábla lúbadh agus bogadh go minic. I gcodarsnacht leis sin, soláthraíonn sciath téipe copair feidhmíocht sciath níos fearr agus friotaíocht creimeadh, rud a fhágann go bhfuil sé an-oiriúnach d'fheidhmchláir ina bhfuil cosaint ard-idirghabhála leictreamaighnéadaigh riachtanach.
Ba cheart an rogha idir cábla rialaithe sciatháilte le fite copair agus cábla rialaithe sciatháilte le téip chopair a dhéanamh bunaithe ar mheasúnú cuimsitheach ar an bhfeidhmchlár agus na riachtanais shonracha. Cinntíonn sé seo go roghnaítear an cineál cábla is oiriúnaí chun freastal ar na riachtanais feidhmíochta agus cosanta atá ag teastáil.
