La presente Norma si applica ai cavi con isolante a base di gomma di qualità G21 (HEPR) sotto guaina elastomerica esente da alogeni di qualità M21. Questi cavi sono del tipo non propaganti la fiamma senza alogeni e utilizzabili per applicazioni in impianti fotovoltaici con tensione nominale Uo/U non superiore a 600/1000 V in corrente alternata e non superiore a 900/1500 V in corrente continua.
La presente Norma ha lo scopo di:

– fornire le regole e i valori costruttivi;
– stabilire le prescrizioni di prova.

I cavi della presente Norma sono indicati per l'interconnessione dei vari elementi degli impianti fotovoltaici. Essi sono adatti per l'installazione fissa all'esterno ed all'interno, senza protezione o entro tubazioni in vista o incassate, o sistemi chiusi similari.
Questi tipi di cavo sono adatti anche per la posa direttamente interrata o tubo interrato secondo le prescrizione della Norma CEI 11-17.
I cavi contenuti nella presente Norma devono possedere la caratteristica di non propagazione della fiamma CEI EN 60332-1-2 (CEI 20-35/1-2), di bassa emissione di fumi CEI EN 61034-2 (CEI 20-37/3-1) e gas tossici CEI 20-37/4-0.
Inoltre, per ciascun componente non metallico deve essere valutata l'assenza di alogeni secondo le modalità indicate nelle Norme CEI EN 50267-2-1 (CEI 20-37/2-1) e CEI EN 50267-2-2 (CEI 20-37/2-2).

What People Are Saying

Thanks to the StandardsClub customer service team for helping me find the ASME BPVC-2023 SET I was looking for in a high-quality PDF version. Their assistance was excellent, and the document quality exceeded my expectations!

This standard document is very detailed, covering all relevant technical points, and provides comprehensive guidance for my project. The ANSI/NEMA Z535 SET was exactly what I needed, and I am very satisfied with the quality!

The purchasing process was straightforward, the price was very competitive, and the download was quick. The Tissue Engineering Standards Addressing Product Quality and Characterization Package was of excellent quality and provided all the information I needed. Definitely a great value for the price!
