DPS cable: kev piav qhia thiab lub hom phiaj ntawm cov khoom

DPS dielectric hom cables yog siv rau lub koom haum ntawm lub ntsiab systems nyob rau hauv qhov chaw uas yog nce yuav tsum tau rau cov neeg kho tshuab stability. Tej khoom yuav stowed nyob rau hauv ib tug cable phwj (blocs hlab, nyob rau hauv lub xub ntiag ntawm high-qib uas yuav tsum tau rau cov neeg kho tshuab stability), lub trench, nyob rau hauv xau 1-3 pab pawg siv automatic riam cable txheej, nyob rau hauv ntau, hla. Qhov no hom ntawm dielectric nyob ntawm tej yuav siv tsis tau nyob rau hauv xau raug kom tsawg kub deformations. Yog tso cai thaum stacking tus kho qhov muag thaiv kuj mus tensile kev nyuaj siab ntawm tsawg kawg yog 20kN. DPS cable muaj ib tug txheej polyethylene hnab.

Tsim DPS cable

Nws muaj cov nram qab qauv:

1. Lub hauv paus ntawm xws li ib tug hlau yog lub hauv paus keeb ntawm lub hwj chim - ib tug dielectric fiberglass pas nrig.
2. Lub fiber optic module nyob rau hauv uas kho qhov muag ntsiab yog nteg dim de mus rau hauv PBT sheath sau nrog ib tug hydrophobic muaj pes tsawg leeg.
3. Intermodule muab tub lim.
4. Tshwj xeeb kho thread.
5. Ib tug polymeric khoom raws li cov intermediate casing.
6. Cov cuab yeej tiv thaiv ntawm galvanized steel nyob ntawm tej.
7. Tshwj xeeb tiv thaiv hose ua los ntawm polymeric cov ntaub ntawv.
8. Insulated tooj liab hlau, uas nws tus ntoo khaub lig seem yog 0.75mm2.

Tsis tas li ntawd, nws yuav tau ua ib tug khaub-ncaws nyias variant: ib tug DPS hwj chim cable tsis muaj lub hauv paus lub cev thiab muaj ib tug kho qhov muag module.

Nta av cables

Cov khoom uas muaj lug siv tsis tau tsuas yog nyob rau hauv cov teb chaws Europe tab sis kuj nyob rau hauv Russia, ua tsaug rau qhov tshwj xeeb uas yuav tsum tau rau kev siv. Piv txwv li, ib tug kho qhov muag cable DPS-hom muaj ib tug siab txhua yam kuj muaj nqis ntawm lub parameter, tsim los rupture. Vim cov cuab yeej, cov nyob ntawm tej yuav siv tau nyob rau hauv ib tug ntau yam ntawm climatic ib ncig chaw. Qhov no yog tshwj xeeb yog muaj tseeb rau peb teb chaws zoo kawg, uas yog tsis tshua muaj thiab huab kub, thiab muaj zog cua, los nag, daus, thiab dej khov. Nyob rau hauv Feem ntau, feem ntau ntawm cov cheeb tsam ntawm Russia yog yus muaj los ntawm hnyav climatic tej yam kev mob, qhov no siv rau ob qho tib si cheeb tsam uas muaj mob loj heev kev nyab xeeb, thiab vice versa, ib yam nkaus thiab loj tsawv. DPS cable tau ntse tsim nws tus kheej nyob rau hauv lub Far East thiab Siberia (nyob rau hauv lub zos xws li Irkutsk, Blagoveshchensk, Petropalovsk-Kamchatsky, Yakutsk, Yuzhno-Sakhalinsk, Magadan thiab Vladivostok). Dielectric cable rau computer networking thiab kev sib txuas lus - rau siv nyob rau hauv xws cov huab cua puag - yuav tsum tau muaj ib tug tshwj xeeb kev zoo siab thiab raws li qhov tsim nyog uas yuav tsum tau nyob rau hauv cov nqe lus ntawm kev ntseeg tau thiab practicality nyob rau hauv kev siv. Neeg kho tshuab stability ntawm lub DPS-hom cables kuj yuav tsum siab, uas yuav pab tau kom tsis txhob ua hauj lwm ntawm kev sib txuas lus kab thiab ua rau kom lub neej ntawm lub tag nrho qhov system.

Siv niaj hnub technologies thiab cov ntaub ntawv nyob rau hauv kev tsim kho ntawm dielectric cables ntawm no hom yog kim heev, tag nrho cov no muaj feem xyuam rau qhov kawg nqi ntawm qhov khoom. Txawm li cas los, nws tsis yog piv nrog rau cov nqi thiab cov teeb meem uas muaj rau kev txhim kho cov builders ntawm tes hauj lwm uas misjudged qhov tseeb kev xaiv ntawm kho qhov muag cables thiab thawj koom ruam rau ib tug sib txawv, kim kim hom, es tsis txhob siv lub DPS cable.
