OPGW Aeirlal wire 24/48 core OPGW fiber optic cable single mode G652D

Central loose tube type

The fibers is placed loosely in a sealed and water resistant stainless steel tube filled with water blocking gel. This tube provides protection to the fiber during installation and operation under severe environmental conditions. Aluminium layer over the tube is optional. The stainless optical tube is located at the center of the cable protected by single or multiple layers 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 controltemperature rise during short circuit conditions.

Multi loose tube ty

Multiple loose tube type

The fibers are enclosed in a water-resistant stainless steel tube containing water-blocking gel. The inner layer of a multi-layer standard cable consists of two or three stainless steel optical tubes that are helically stranded. The multiple loose tube type is suitable for high fiber count demands (over 48 fibers) with a maximum of 144 fibers. It can meet the requirements of large current capacity and extensive cross-sections.

Application

The OPGW serves as both a ground wire and communication system on new power lines, particularly on normal and extra high-voltage lines. It can replace conventional ground wires, providing added fiber communication and offering short circuit current and lightning resistance.

OPGW cables are primarily used on 500KV, 220KV, and 110KV lines. They are typically employed in new lines due to power cut and security limitations. They are best suited for high-voltage lines over 110KV with long spans (typically exceeding 250 meters).
