Electric cables for photovoltaic systems with a voltage rating of 1,5 kV DC
IEC 62930:2017(E) applies to single-core cross-linked insulated power cables with cross-linked sheath. These cables are for use at the direct current (DC) side of photovoltaic systems, with a rated DC voltage up to and including 1,5 kV between conductors and between conductor and earth. This document includes halogen free low smoke cables and cables that can contain halogens.
The cables are suitable to be used with Class II equipment as defined in IEC 61140.
The cables are designed to operate at a normal continuous maximum conductor temperature of 90 °C. The permissible period of use at a maximum conductor temperature of 120 °C is limited to 20 000 h.
Električni kabli za fotonapetostne sisteme z enosmerno (DC) napetostjo 1,5 kV (IEC 62930:2017)
Ta dokument se uporablja za enožilne zamrežene izolirane napajalne kable z zamreženo oblogo. Ti kabli se uporabljajo na enosmerni (DC) strani fotonapetostnih sistemov z nazivno enosmerno napetostjo do 1,5 kV med vodniki ter med vodnikom in ozemljitvijo. Ta dokument vključuje kable z majhno gostoto dima brez halogenov in kable, ki lahko vsebujejo halogene. Kabli so primerni za uporabo z opremo razreda II, kot je opredeljeno v standardu IEC 61140.
Kabli so zasnovani za delovanje pri običajni enakomerni najvišji temperaturi vodnika 90 °C. Dopustno obdobje uporabe pri najvišji temperaturi vodnika 120 °C je omejeno na 20.000 h.
OPOMBA: Pričakovano obdobje uporabe v običajnih pogojih uporabe, kot je določeno v tem dokumentu, znaša 25 let.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

INTRODUCTION
This document specifies cables for use in photovoltaic (PV) systems for installation at the
direct current (DC) side. These cables are suitable for permanent outdoor long-term use
under variable demanding climate conditions. Relatively stringent requirements are set for
these products in line with the expected usage conditions.
During the writing of this document, the work of IEC TC 64 (Electrical installations and
protection against electric shock) and IEC TC 82 (Solar photovoltaic energy systems) on the
design and installation of PV systems has been taken into account.
