Forniscono alimentazione e trasmettono segnali di comando ai macchinari che si muovono avanti e indietro lungo binari di guida fissi. A differenza dei cavi progettati per resistere alla torsione, i cavi a festone sono appositamente progettati per adattarsi ai movimenti di flessione ondulatoria tipici dei sistemi a festone. Durante il funzionamento, i cavi subiscono ripetute flessioni e raddrizzamenti, pur sopportando una tensione intrinseca.<\/div>\n<\/div>\n<div>\n<h2>1. Sollecitazioni operative principali<\/h2>\n<\/div>\n<div>\n<div>I cavi festonati sono sottoposti a diversi tipi di sollecitazioni meccaniche prolungate:<\/p>\n<div><\/div>\n<p>Cicli di piegatura a rotazione: durante il funzionamento, il cavo sospeso forma archi curvi e si distende quando viene raccolto a un\u2019estremit\u00e0 del binario. Questo movimento si svolge ininterrottamente 24 ore su 24.<\/p>\n<div><\/div>\n<p>Abrasione superficiale: la guaina esterna sfrega costantemente contro i carrelli a festone e i cavi adiacenti all\u2019interno del sistema, il che richiede una robusta resistenza all\u2019usura.<\/p>\n<div><\/div>\n<p>Forza di trazione: il cavo deve sostenere il proprio peso lungo la campata tra i carrelli. Un allungamento eccessivo pu\u00f2 causare strascicamento, inceppamenti e guasti meccanici.<\/p>\n<div><\/div>\n<p>Condizioni ambientali complesse: la maggior parte delle unit\u00e0 viene installata all\u2019aperto o all\u2019interno di grandi capannoni industriali. Sono soggette a radiazioni UV, invecchiamento da ozono, sbalzi di temperatura, nonch\u00e9 a potenziali contatti con grassi e sostanze chimiche industriali.<\/p><\/div>\n<\/div>\n<div>\n<h2>2. Progettazione strutturale e vantaggi tecnici<\/h2>\n<\/div>\n<div>\n<div>Conduttori: vengono utilizzati conduttori in rame a trefoli ultra-sottili caratterizzati da elevata flessibilit\u00e0. La struttura ottimizzata dei trefoli consente il libero movimento relativo dei singoli trefoli di rame, distribuendo uniformemente le sollecitazioni da flessione ed evitando l\u2019affaticamento del metallo e la rottura del conduttore.<\/p>\n<div><\/div>\n<p>Strato isolante: materiali flessibili specializzati, tra cui l\u2019elastomero termoplastico (TPE) e la gomma etilene-propilene (EPR), sostituiscono il comune PVC. Questi materiali mantengono la flessibilit\u00e0 alle basse temperature e resistono alle fessurazioni anche dopo milioni di cicli di flessione.<\/p>\n<div><\/div>\n<p>Guaina esterna: la guaina determina in larga misura la durata di vita utile del cavo. Il poliuretano (PUR) \u00e8 la scelta pi\u00f9 diffusa, in quanto offre una resistenza all\u2019abrasione eccezionale, di gran lunga superiore a quella del PVC. Presenta inoltre un\u2019affidabile resistenza all\u2019olio, all\u2019erosione chimica e agli strappi.<\/p>\n<div><\/div>\n<p>Struttura interna: tutte le anime interne sono intrecciate con una lunghezza di avvolgimento bilanciata per evitare deformazioni e rigonfiamenti in caso di flessioni ripetute. Alcune specifiche prevedono l\u2019utilizzo di materiali di riempimento non assorbenti, come il filato di polipropilene, che impediscono la diffusione dell\u2019umidit\u00e0 anche in caso di lievi danni alla guaina esterna.<\/p><\/div>\n<\/div>\n<div>\n<h2>3.
