(Main)Power cables with extruded insulation and their accessories for rated voltages from 1 kV (Um = 1,2 kV) up to 30 kV (Um = 36 kV) - Part 2: Cables for rated voltages from 6 kV (Um = 7,2 kV) up to 30 kV (Um = 36 kV)
Power cables with extruded insulation and their accessories for rated voltages from 1 kV (<i>U</i><sub>m</sub> = 1,2 kV) up to 30 kV (<i>U</i><sub>m</sub> = 36 kV) - Part 2: Cables for rated voltages from 6 kV (<i>U</i><sub>m</sub> = 7,2 kV) up to 30 kV (<i>U</i><sub>m</sub> = 36 kV)
IEC 60502-2:2014 is available as IEC 60502-2:2014 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60502-2:2014 specifies the construction, dimensions and test requirements of power cables with extruded solid insulation from 6 kV up to 30 kV for fixed installations such as distribution networks or industrial installations. When determining applications, it is recommended that the possible risk of radial water ingress is considered. Cable designs with barriers claimed to prevent longitudinal water penetration and an associated test are included in this part of IEC 60502. Cables for special installation and service conditions are not included, for example cables for overhead networks, the mining industry, nuclear power plants (in and around the containment area) nor for submarine use or shipboard application. This third edition cancels and replaces the second edition, published in 2005, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) a simplified calculation procedure for the thickness of the lead sheath and the oversheath;
b) a new subclause for the determination of the cable conductor temperature;
c) a modified procedure for the routine voltage test;
d) a new subclause for a routine electrical test on oversheath;
e) modified requirements for the non-metal sheaths including semi-conductive layer;
f) modified tolerances for the bending test cylinder;
g) the inclusion of a 0,1 Hz test after installation.
In addition, the modified structure of the IEC 60811 series has been adopted for this third edition.
Câbles d'énergie à isolant extrudé et leurs accessoires pour des tensions assignées de 1 kV (<i>U</i><sub>m</sub> = 1,2 kV) à 30 kV (<i>U</i><sub>m</sub> = 36 kV) - Partie 2: Câbles de tensions assignées de 6 kV (<i>U</i><sub>m</sub> = 7,2 kV) à 30 kV (<i>U</i><sub>m</sub> = 36 kV)
IEC 60502-2:2014 est disponible sous forme de IEC 60502-2:2014 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
IEC 60502-2:2014 spécifie la constitution, les dimensions et les exigences d'essais des câbles d'énergie à isolation extrudée par diélectriques massifs, de tensions assignées de 6 kV à 30 kV, pour installations fixes telles que les réseaux de distribution ou les installations industrielles. Pour la conception des câbles, il est recommandé de tenir compte du risque possible d'une entrée d'eau radiale. Les câbles dont la conception est déclarée comporter une barrière d'étanchéité longitudinale à l'eau et les essais qui y correspondent sont inclus dans cette partie de la CEI 60502. Les câbles destinés à des conditions particulières d'installations et de service ne sont pas inclus, par exemple, les câbles pour réseaux aériens, pour l'industrie minière, pour les centrales nucléaires (à l'intérieur et à l'extérieur de l'enceinte de confinement), les câbles sous-marins ou les câbles de bord des navires. Cette troisième édition annule et remplace la deuxième édition publiée en 2005 et constitue une révision technique. Des changements techniques significatifs ont été apportés par rapport à la deuxième édition:
a) une procédure de calcul simplifié pour l'épaisseur de la gaine de plomb et de la gaine extérieure;
b) un nouveau paragraphe concernant la détermination de la température de l'âme du câble;
c) une procédure modifiée des essais individuels de tension;
d) un nouveau paragraphe concernant l'essai individuel électrique de la gaine extérieure;
e) les exigences modifiées pour les gaines non métalliques y compris une couche semi-conductrice;
f) les tolérances modifiées concernant l'essai d'enroulement d'un cylindre d'essai;
g) l'ajout d'un essai sous 0,1 Hz après l'installation.
De plus, la structure modifiée de la série CEI 60811 est adoptée dans cette troisième édition.
Elektroenergetski kabli z ekstrudirano izolacijo in njihov pribor za naznačene napetosti od 1 kV (Um = 1,2 kV) do 30 kV (Um = 36 kV) - 2. del: Kabli za naznačene napetosti od 6 kV (Um = 7,2 kV) do 30 kV (Um = 36 kV)
Standard IEC 60502-2:2014 je na voljo kot IEC 60502-2:2014 RLV, ki vsebuje mednarodni standard in njegovo različico z revizijami, ki prikazujejo vse spremembe tehnične vsebine v primerjavi s prejšnjo izdajo.
Standard IEC 60502-2:2014 določa izvedbo, dimenzije in preskusne zahteve za elektroenergetske kable, izolirane s trdim ekstrudiranim materialom, z napetostjo od 6 kV do 30 kV, ki se uporabljajo za fiksne napeljave, kot so distribucijska omrežja ali industrijske napeljave. Pri določanju načinov uporabe naj se upošteva morebitno tveganje radialnega vdora vode. Ta del standarda IEC 60502 vključuje zasnove kablov s pregradami, ki naj bi preprečevale vzdolžno prodiranje vode, in s tem povezane preskuse. Kabli, za katere veljajo posebni pogoji namestitve in delovanja, kot so kabli za nadzemna omrežja, rudarsko industrijo, jedrske elektrarne (na kraju samem in v njegovi okolici), uporabo v podmornicah ali na ladjah, niso vključeni. Ta tretja izdaja razveljavlja in nadomešča drugo izdajo, objavljeno leta 2005, in predstavlja tehnično popravljeno izdajo. Ta izdaja v primerjavi s prejšnjo vključuje naslednje pomembne tehnične spremembe:
a) poenostavljen postopek za izračun debeline svinčenega in zunanjega plašča;
b) nova podtočka o določanju temperature kabelskih vodov;
c) spremenjen postopek za rutinski preskus napetosti;
d) nova podtočka o rutinskem električnem preskušanju na zunanjem plašču;
e) spremenjene zahteve za nekovinske plašče, vključno s polprevodnim slojem;
f) spremenjene tolerance za cilinder, ki se uporablja pri preskusu z upogibanjem;
g) vključitev preskusa z 0,1 Hz po namestitvi.
Poleg tega se v tej tretji izdaji uporablja spremenjena struktura skupine standardov IEC 60811.
