Reliable OPGW Ground Wire with IEEE 1135 Standard for Lightning Protection & Short Circuit

OPGW (Optical Fiber Composite Overhead Ground Wire) is specifically designed for communication lines in high voltage power transmission systems of 35KV and above. It serves dual purposes: replacing existing ground wires in overhead high voltage systems while adding communication capabilities, and providing short-circuit current conduction and lightning protection.

The cable features a small diameter design that minimizes additional load on poles and towers. Its stainless steel tube construction provides excellent fiber protection with high tensile strength. The optical unit resides in the cable's interlayer, offering superior twist resistance and lateral pressure performance.

Two primary constructions are available:

1. Central Loose Tube Type: Fibers are loosely placed in a water-resistant stainless steel tube filled with blocking gel. This design accommodates up to 48 fibers while maintaining high mechanical strength and excellent sag tension performance.

2. Multi Loose Tube Type: Designed for higher fiber counts (up to 144 fibers), this version features multiple stainless steel optical tubes helically stranded in the inner layer, suitable for applications requiring huge cross-sections and large current capacity.

Key advantages include:

- Compact design with powerful tensile strength

- Excellent safety and shooting resistance performance

- Anti-theft characteristics

- Flexible armor combinations to meet various electrical and mechanical requirements

The product complies with IEEE 1135 standard and is packed in wooden or iron-wooden drums for optimal protection during transportation.
