Fil de masse en fibre optique composite (OPGW)
1. Application
OPGW est principalement appliqué dans la ligne de communication du système de transmission électrique à haute tension nouvellement construit avec 35 KV
ou au-dessus, ou le remplacement du fil de masse existant du système d'électricité de transmission haute tension aérienne antérieur, en ajoutant
de lignes de communication et de conduite du courant de court-circuit ou de protection contre la foudre.
2. Avantage
☀ Le diamètre du câble est petit avec une faible charge supplémentaire sur le poteau et la tour.
☀ La conception du tube en acier inoxydable est raisonnable et les longueurs excédentaires de la fibre sont correctes.
☀ Le tube en acier inoxydable protège la fibre avec une puissante résistance à la traction.
☀ L'unité optique du tube en acier inoxydable est la couche intermédiaire du câble et elle peut résister à la torsion et a de bonnes performances de pression latérale.
☀ Avec de bonnes performances de sécurité et de fortes performances de résistance au tir, pas facile à voler
☀ Différentes combinaisons d'armures ou rencontrer différentes combinaisons de propriétés électriques et mécaniques.
3. Diagramme de section
Le câble OPGW a deux constructions:
Type de tube central lâche --- Les fibres sont placées lâches dans un tube en acier inoxydable scellé et résistant à l'eau rempli de blocage d'eau
gel. Ce tube protège la fibre pendant l'installation et le fonctionnement dans des conditions environnementales sévères. aluminium
couche sur le tube est facultative. Le tube optique inoxydable est situé au centre du câble protégé par des couches simples ou multiples
of aluminium clad steel and aluminium annoy wires. The aluminium clad steel wires are shaped trapezoidally around the optical
unit to provide compact construction. The metallic wires provide mechanical strength to withstand severe installation and operating
conditions, while achieving conductivity to control temperature rise during short circuit conditions.
This type can accommodate up to 48 fibers in a cable. Despite such a high fiber count in a single tube, each optical fiber is clearly
distinguishable utilizing a fiber identification system consisting of coloring and the number of ring marks on it. This compact design
features high mechanical strength and fault current rating within a smaller diameter. The smaller diameter also results in excellent sag
tension performance.
Multi loose tube type--- The fibers is placed loosely in a sealed and water resistant stainless steel tube filled with water blocking gel.
Two or three stainless steel optical tubes are helically stranded in the inner layer of a multiple-layer cable.
The multi loose tube type is designed mostly for very high fiber count requirement over 48 with the maximum fiber count reaching 144.
The multi loose tube type can meet the requirement of huge cross and large current capacity.
