1.0 Generalitati

1.1 Domeniu de aplicare

Prezenta norma se aplica in cadrul Petrom / OMV pentru proiectarea si executia traseelor de cablu pozate subteran, pentru echipamente electrotehnice / alimentare de curent tare si pentru echipamente de masurare si reglare / alimentare de curent slab.

1.2 Norme si reglementari

Impreuna cu prezenta norma se vor respecta dispozitiile, normele si directivele valabile in Romania, in varianta lor aflata in vigoare, care sunt mentionate in Anexa. Nu consideram enumerarea noastra ca fiind una completa Daca intre diferitele dispozitii, reglementari, norme si directive apar diferente sau contradictii, iar aspectele respective nu sunt in mod expres clarificate prin prezenta norma, se va aplica reglementarea cu formularea cea mai restrictiva. In cazul in care prevederile se exclud reciproc, atunci se va aplica reglementarea prevazuta de legislatia din Romania. Intra in responsabilitatea executantului sa verifice daca prevederile prezentei norme sunt adecvate scopului lucrarii respective. Aplicarea normei nu il degreveaza pe executant de raspunderea pe care o are in calitate de antreprenor profesionist si responsabil. Daca executantul are obiectii cu privire la una dintre prevederile stabilite, el il va informa imediat in scris pe angajator despre acest lucru.

1.3 Trasee de cabluri

In zona suprafetelor consolidate din amplasamentele de instalatii, pozarea cablurilor se face fie in jgheaburi fie in tuburi de protectie. Ca alternativa la tuburile de protectie, se pot folosi si discuri de tragere cabluri, din beton daca exista aprobare din partea responsabilului

1.0 General

1.1 Scope

This Standard applies within the Petrom/ OMV for the planning and construction of subterranean cable lines laid for electrical engineering / high voltage current supply and measuring and regulation technology /low voltage current technology.

1.2 Standards and Regulations

In conjunction with this Standard, the respective specifications, standards and directives legally applicable in Romania and stated in the Annex should be taken into account in their currently valid form.

This listing is not claimed to be complete. In the event of differences or conflicts arising between the various specifications, standards and regulations and where there is no firm definition provided by this standard, the strictest formulation is to be applied in each case. Where they are mutually exclusive, the Romanian statutory regulations will apply. The contractor will be responsible for checking the appropriateness of this standard for the intended purpose. The application does not relieve the contractor of his responsibility as specialist and independent entrepreneur. If the contractor has reservations concerning an agreed definition, he must notify the client of this in writing without delay.

1.3 Cable lines

In the area of fixed plant surfaces, the cable is to be laid either in cable troughs or in cable conduit. As an alternative to cable conduit, cable drawing dies made of concrete can also be used - as long as it has approval from the project management

Norma Petrom OMV A 3003 / Petrom OMV Standard A 3003 Pag / Page 3

de proiect - (adaptarea echipamentelor existente). In amplasarea traseelor de cabluri si a caminelor de vizitare, se va face separarea completa a cablurilor de curent tare de traseele de cabluri pentru echipamentele de masurare si reglare. In cazul desfasurarii in paralel a traseelor de cablu, se va pastra o distanta minima intre ele de 1,00 m iar in zonele de incrucisare se va pastra o diferenta de nivel de min. 0,70 m. Daca din motive tehnice, distantele mai mici decat cele indicate sunt de neevitat, se vor executa sisteme de ecranare, conform Normei Petrom OMV K 3292. La subtraversarile din zona strazilor, liniilor de cale ferata, jgheaburilor de conducte etc., pozarea cablurilor se va face in tuburi de protectie. La suprafetele neconsolidate, cablurile vor fi pozate in mod normal in santuri de cablu, conform Normei Petrom/OMV N 3004. Latimea traseelor se deduce din numarul de cabluri si distantele de libera trecere necesare; daca se folosesc tuburi de protectie, latimea traseelor se deduce din modul de dispunere a tuburilor. Din motive de spatiu, trebuie sa se execute trasee pentru tuburi de protectie, inguste si in mai multe straturi in loc de trasee late, intr-un strat (nivel).

(adjustment to old status). When finding the location for the cable lines and the draw shafts, the high voltage current and the MSR lines must be fully disconnected. If the cable lines are laid parallel to each other there must be a minimum separation of 1.00 m and, for cross-overs, a height difference of min. 0.70 m must be maintained. If smaller distances are difficult for technical reasons, then screens must be created according to Petrom OMV Standard K 3292. For going under streets, railways systems, piping troughs, the cable is to be laid in cable conduit. For unfixed surfaces, the cables are normally laid in cable chutes in compliance with Petrom/OMV Standard N 3004. The width of the lines is created by the number of cables and their required separation; in the case of cable conduits, the width comes from the arrangement of the required cable conduits. For reasons of space, narrow, multilayered cable conduit lines should be used instead of one wide layer.

2.0 TUBURI DE PROTECTIE A CABLURILOR Ca tuburi de protectie se vor folosi:

Tub de protectie rigid 110 MS-SB (negru)sau

110 MS-SB (gri) conform

NORM E 6510

Tub de protectie flexibil 100 MS-SB sau

125 MS-SB (negru) conform

Cable conduit must be laid on a clean layer with min. 5 cm thickness and concrete quality B 80. If the cleanliness layer is exposed to static loads, the sub-concrete must be executed according to the static requirements.


incarcare statica. Tuburile pot fi pozate intr-un strat sau in mai multe straturi. Tuburile vor fi fixate prin distantiere, elemente de tensionare si intindere adecvate. In tuburi va fi inserat un conductor (sarma) zincat, cu diametrul de 3 mm, pentru a facilita montarea ulterioara a cablurilor. Orificiile terminalelor vor fi inchise cu busoane de inchidere. Tuburile de protectie vor fi acoperite in lateral si in partea de sus cu un strat de beton de umplutura SSM, cu grosimea de min. 10 cm. Betonul de umplutura va fi amestecat cu un fluidificator..Executia se va face in functie de cerintele de rezistenta pe care trebuie sa le indeplineasca traseele. Inaltimea stratului de acoperire a tuburilor de protectie in zona intersectiilor de strazi trebuie sa nu fie mai mica de 50 cm. Adancimea de pozare conform Normei Petrom/OMV N 3004.

The pipes can be laid in single or multilayer. The pipes must be fixed with suitable spacers, bracings and strippers. Insert a galvanised wire, diameter 3 mm, in the conduit to simplify subsequent cable assembly. The end openings must be closed off with drain plugs. The cable conduits are to be sheathed at the sides and above with lean-mix concrete SSM, min. 10 cm thick. A liquefier must be added to the lean-mix concrete. It must be implemented according to the stability requirements of the line control. The cover height of the cable conduit at street intersections and similar must not be less than 50 cm.

2.1 Discuri de tragere cabluri

Discurile de tragere cu 4 canale (discuri intregi respectiv segmentate, la cablurile vechi) vor fi pozate pe stratul de beton de rezistenta, conform instructiunilor producatorului. Discurile vor fi prinse cu dibluri iar rosturile vor fi acoperite cu straturi de etansare cu bitum cu grosimea de min. 15 cm. Canalele de tragere ale discurilor vor fi calibrate. In canale va fi inserat un conductor (sarma) zincat, cu diametrul de 3 mm, pentru a facilita montarea ulterioara a cablurilor. Orificiile terminalelor vor fi inchise cu busoane de inchidere. Inaltimea stratului de acoperire a discurilor de tragere cabluri in zona intersectiilor de strazi trebuie sa nu fie mai mica de 40 cm

2.1 Cable drawing dies

The four-form cable drawing dies (complete dies or divided dies for existing cables) must be laid on sub-concrete according to the manufacturer's stipulations. The dies must be doweled and the joints must be covered with min. 15 cm wide bitumen waterproof sheeting. The dies of the cable drawing dies must be calibrated. In the sections, insert a galvanised wire, diameter 3 mm to simplify subsequent cable assembly. The end openings must be closed with drain plugs. The cover height of the cable drawing dies at street intersections and similar must not be less than 40 cm.

3.0 CAMINE DE VIZITARE A CABLURILOR

3.1 Dimensiuni

La traseele drepte (in aliniament), dimensiunea caminelor nu depinde de latimea traseelor si de spatiul de lucru necesar.

Daca traseul este in unghi, dimensiunea va depinde de raza minima de curbare (indoire) a cablurilor.

La traseele de mare lungime cu tuburi de protectie a cablurilor, caminele de vizitare vor fi stabilite pentru fiecare caz in parte, pentru montarea instalatiilor de intindere.

Inaltimea caminelor depinde de adancimea de pozare, conform Normei Petrom/ OMV N 3004, si de numarul de nivele (straturi) de tuburi.

Dimensiunea de gabarit a caminelor este de min. 1,50 x 1,50 m (vezi Fig. 2). Racordurile inclinate ale turburilor de protectie vor fi slefuite, tinand cont de raza minima de curbare a cablurilor.

3.0 CABLE DRAWING SHAFTS

3.1 Size

The size of the cable laying chutes for straight cable lines is independent of the line width and the required work space.

If the line flows at an angle, the size also depends on the minimum cable arc radius.

In long cable conduit lines, the laying chutes for installation of cable laying machines must be determined in individual cases.

The height of the cable laying chutes depends on the laying depth according to Petrom/ OMV Standard N 3004 and the number of pipe layers.

The chute clearance is to be minimum 1.50 x 1.50 m (see Fig. 2). Inclined cable conduit junctions must be laid in loops, observing the minimum cable arc radius.

3.2 Talpa de fundatie

La caminele de vizitare cabluri, in mod normal, talpa de fundatie este terenul (solul) de baza. In cazul terenurilor cu pietris cu granulatie mare se va executa un strat corespunzator de filtrare. Talpa de fundatie din beton de rezistenta va fi prevazuta numai daca este necesar din punct de vedere al rezistentei, executandu-se si orificiile aferente de infiltrare. Daca traseele de cabluri prezinta diferente de nivel, talpa de fundatie trebuie sa fie adaptata la variatia de nivel. Unghiul de inclinare a talpii trebuie sa nu depaseasca 45. La o variatie de nivel de pana la 1,20 m va fi prevazuta o suprafata de rezemare joasa, la variatii peste 1,20 m va fi prevazuta o suprafata inalta de rezemare (vezi Fig.4).

3.2 Base

In cable laying chutes, the base is normally the sub-ground. On ground with rough rubble, an appropriate filter layer must be laid. A base formation with sub-concrete must be provided only in case of static requirements, whereby suitable drain openings must be incorporated. With different level of cable lines, the base must be adjusted to the level step. The inclination angle of the base must not exceed 45 degrees. Up to 1.20 m step height, provide a lower floor space, above 1.20 m step height another upper floor space must be provided (see Fig. 4).

3.3 Peretii

Se va opta pentru o varianta economica, tinand cont de cerintele de rezistenta. De regula, peretii sunt executati din placi de beton cu grosimea de 20 cm, cu beton de umplutura B 160 respectiv B 225, cu rost in partea de sus respectiv cu beton de egalizare B 225.

3.4 Acoperirea

In zonele in care se circula, acoperirea va fi realizata cu blocuri prefabricate de beton armat sau imbracaminte combinata cu bitum.

In varianta cu blocuri prefabricate de beton armat, spatiul dintre capacele de PVC pentru cabluri si blocurile de beton va fi umplut cu nisip; in varianta cu imbracaminte pe baza de bitum, tuburile de protectie a cablurilor vor fi ingropate in nisip pana la 15 cm peste marginea superioara a tuburilor, peste care se va turna materialul de protectie la inghet si apoi

3.3 Walls

Ensure economic implementation according to the respective stability requirements. Generally, the walls must be made of 20 cm thick concrete board blocks with lean-mix concrete B 160 or B 225 with upper grid or equalising concrete B 225.

3.4 Cover

For traversible surfaces, the cover must be made of reinforced concrete pre-assembled boards or bitumen mix.

For pre-assembled board covers, the intermediate space between the PVC cable covers to the boards must be filled with sand, with bitumen mix layer cover, the cable conduits must be covered with sand up to 15 cm above the top of the pipe, filled and compacted with antifrost material above.
