Power and Optical Cable Connection Fittings

Power and optical cable fittings are specialized components designed to securely connect, support, and protect overhead power lines and fiber optic cables, ensuring mechanical stability and reliable data or power transmission.

Optical cable fittings, such as RIBE OPTOFIT® products, are specifically developed for aerial fiber optic cables used in modern communication networks. These fittings include joint boxes, termination units, and adapters that protect optical fibers from environmental factors like water, humidity, and mechanical stress, often achieving IP67 tightness for high protection. They are designed for easy assembly, covering cable diameters from 9 mm to 28.6 mm, and are suitable for OPGW (Optical Ground Wire) and ADSS (All-Dielectric Self-Supporting) cables. The fittings ensure long-term reliability of data transmission by maintaining fiber integrity and minimizing signal loss .

Power fittings are used to connect conductors, optical cables, towers, and insulators in overhead transmission and distribution systems. Common types include cable clamps, dead-end clamps, ball clevis, stay rods, and hexagonal bolts. These fittings are made from aluminum, copper, steel, or composite materials to withstand mechanical and electrical loads. High-performance fittings can handle tension strengths up to 1227 kN and are suitable for UHV projects up to 1000 kV AC and ±1100 kV DC. They are designed to meet international standards such as IEC, ICEA, AS, BS, DIN/VDE, and IS, and can be customized for extreme conditions like heavy ice, low temperatures, or river crossings .

• Durability and Reliability: Both optical and power fittings are tested for long-term performance under environmental and mechanical stress.
• Ease of Installation: Preformed and modular designs allow fast, cost-efficient on-site assembly.
• Custom Solutions: Manufacturers provide tailored fittings for specific cable types, diameters, and project requirements.
• Environmental Considerations: Some manufacturers, like RIBE, operate climate-neutral production facilities and focus on sustainable materials .

• Telecom and Data Networks: Aerial fiber optic cables for high-speed data transmission.
• Power Transmission and Distribution: Overhead lines, substations, and rural distribution networks.
• Special Projects: UHV lines, heavy ice regions, river crossings, and renewable energy installations.

In summary, power and optical cable fittings are critical for ensuring the mechanical integrity and operational reliability of both electrical and communication infrastructures, with specialized designs for different cable types, environmental conditions, and load requirements .
