Cur síos ar an Táirge
Táirgeann ár monarcha cáblaí ísealvoltais lasmuigh comhdhéanta de thrí chuid: an seoltóir, an ciseal inslithe, agus an ciseal cosanta. Is gnách go mbíonn an seoltóir, a úsáidtear chun sruth a sheoladh, déanta as snáitheanna iolracha de shreang copair nó alúmanaim atá casta le chéile. Tá oibriú iontaofa ag an táirge, ní gá cuaillí, aon áitiú talún, cuma gan bhac, agus an claonadh is lú i leith tionchair sheachtracha, rud a fhágann go n-úsáidtear go forleathan é i gcórais dáileacháin cumhachta ísealvoltais.

Gné Táirge agus Feidhm
Go ginearálta tá trí mhodh ann chun cáblaí ísealvoltais lasmuigh a leagan:
◆ Adhlacadh Díreach
- Is é seo an modh is coitianta. Riachtanais Doimhneachta Adhlactha:I ngnáthcheantair, ba chóir go mbeadh an truaill cábla ar a laghad 0.7m faoi leibhéal na talún. I dtalamh feirme nó bóithre, ba cheart go mbeadh an doimhneacht adhlactha 1.0m ar a laghad. Nuair a bhíonn mórbhealaí nó iarnróid á dtrasnú, tá gá le seoltán cruach cosanta, le doimhneacht adhlactha 0.8m ar a laghad agus clúdach ithreach ar a laghad 1.0m os cionn an seoladáin.
- Bearta Cosanta:Ba chóir ciseal 100mm tiubh de ghaineamh fíneáil nó ithir bog a leagan os cionn agus faoi bhun an chábla, agus ba chóir é a chlúdach le leaca coincréite nó brící le haghaidh cosanta. Ba cheart cuaillí marcála cábla a shuiteáil ag bends, joints, agus crosbhealaí le haghaidh cothabhála éasca.
- Inoiriúnaitheacht Timpeallachta:Agus an leagan á phleanáil, seachain limistéir le píopaí teasa, creimeadh ceimiceach, agus foinsí creathadh meicniúla. Coinnigh achar sábháilte ó phíblínte eile.
◆ Leagan Seoladán:
- Tá an modh seo oiriúnach chun bóithre, foirgnimh, nó limistéir leochaileacha a thrasnú.
- Riachtanais trastomhas píopa:Ba chóir go mbeadh trastomhas istigh an phíobáin chosanta níos mó ná nó cothrom le 1.5 uair trastomhas seachtrach an chábla.
- Riachtanais séalaithe:Ba chóir go mbeadh an píopa séalaithe agus uiscedhíonach, agus ba chóir go mbeadh foircinn an phíobáin go réidh chun an ciseal inslithe cábla a scratáil.
◆ Tráidire cábla / trinse cábla a shuiteáil:
- Éilíonn an cás seo suiteáil cisealta. Ba cheart leibhéil voltais éagsúla a bheith cisealta, le voltas ard ar an mbarr agus voltas íseal ar an mbun, scartha le landairí. Ina theannta sin, ní mór an tráidire cábla miotail a thalamh ar fud chun leanúnachas leictreach a chinntiú.

C: Conas cábla ísealvoltais lasmuigh oiriúnach a roghnú?
A: Chun cábla ísealvoltais lasmuigh a roghnú, ní mór aird a thabhairt ar fhachtóirí mar leibhéal voltais, timpeallacht leagan, neart meicniúil agus inoiriúnaitheacht aeráide. Molaimid go mór ár gcábla armúrtha le téip chruach inslithe poileitiléin tras-nasctha. Tá friotaíocht íseal teochta, friotaíocht brú agus friotaíocht taise ag an gcineál seo cábla, rud a fhágann go bhfuil sé oiriúnach le haghaidh adhlactha díreach, suiteáil seoladáin, agus suiteáil i dtír-raon casta.
