Serbian term or phrase: uvodnica
Prema Glavnoj 113 vide se dve cevi koje su uvodnice. Kroz jednu uvodnicu prolazi kabl koji dalje nastavlja kroz zemlju.

Pokušano pomeranje kabla tj. provera da li je kabl ukopan, i potvrđeno da postoji samo uvodnica, a ne i privod, odnosno da je kabl ukopan i nema kablovske kanalizacije.

Postoji jedna velika uvodnica po tehničkoj dokumentaciji. Nema tehničkih mogućnosti, jer ne postoje dve velike cevi.

direct-buried raceway that terminates underground
Explanation:
"The shortest distance in millimeters (inches) measured between a point on the top surface of any
direct-buried conductor, cable, conduit, or other raceway and the top surface of finished grade, concrete, or similar
cover."

https://www.nfpa.org/assets/files/aboutthecodes/70/nec_p03_r...

"A bushing, or terminal fitting, with an integral bushed opening shall be installed on the end of a conduit or other raceway that terminates underground where the conductors or cables emerge as a direct burial wiring method. A seal incorporating the physical protection characteristics of a bushing shall be considered equivalent to a bushing. [300.5(H)]"

Explanation:
1. https://webcache.googleusercontent.com/search?q=cache:gFGo7b...

OPGW mreža CGES-a se završava u trafostanici na portalnom stubu dalekovoda, odakle se podzemnim privodnim optičkim kablom povezuje sa optičkim razdjelnikom (ODF) koji se nalaze u zgradi trafostanice.

Podzemni privodni optički kabl treba da ima iste prenosne karakteristike kao i OPGW. Optička vlakna treba da su identična kao kod OPGW-a, tako da je kapacitet privodnog optičkog kabla 48 optičkih vlakana (24 x G.652D + 24 x G.655C). Ovaj kabl će biti položen u betonske kanale. Duž čitave trase biće položen u zaštitne PEHD cijevi Ø50mm koje su na krajevima zatvorene termoskupljajućom zaštitnom glavom radi zaštite od prodora vlage. Ovaj kabl se unutar zgrade štiti od mehaničkih oštećenja provlačenjem kroz PVC savitljive cijevi odgovarajućeg prečnika.

Podzemni optički kabl treba da je nemetalne konstrukcije sa dvostrukim omotačem i zaštitnim slojem od staklenih vlakana za zaštitu od glodara i sa zaštitnim omotačem koji ne podržava gorenje. Centralni rasteretni element treba da bude nemetalni, plastika ojačana fiber vlaknima. Cjevčice za optička vlakna, kao zaštita vlakana, treba da budu plastične. Optička vlakna uvučena u cjevčice zajedno sa gelom koji sprečava ulazak vode. Punjenje kabla treba da je sa nepropusnom masom za blokadu vode. Pojasnu izolaciju čine trake za blokadu vode, a omotač kabla treba da bude izrađen od polietilena.

Prilikom polaganja privodnog optičkog kabla i zaštitne PEHD cijevi mora se voditi računa o poluprečnicima savijanja koji iznose:

za optički kabl: rmin = 150 mm;
za zaštitnu PEHD cijev: rmin = 700mm.

disagree  Daryo: All your refs are OK, but s.t. is still missing // "uvodnica" IS NOT a "conduit, duct, trunking" it's only s.t. at the begining of it used to "introduce" the cable into the conduit.// radi poređenja: deo koji ide na kraj nekog creva nije "crevo".
