Bulgarian OPGW Fittings OS2

OPGW fittings for OS2 fiber optic cables include suspension, tension, link, and vibration-damping assemblies designed to meet international standards and withstand extreme mechanical and environmental conditions.

Overview of OPG

W FittingsOPGW (Optical Ground Wire) fittings are hardware components that connect fiber optic cables to transmission towers, ensuring both mechanical stability and electrical grounding. They are essential for carrying mechanical loads, lightning protection, and maintaining fiber integrity in overhead line networks. Fittings are designed for various applications, including ultra-high voltage lines, long spans, and harsh environmental conditions.

Common Types of OPGW Fittings

Suspension Assemblies: Support the cable along the tower span while allowing slight movement to reduce stress. Tension Assemblies: Secure the cable at anchor points, handling high mechanical loads. Link Fittings: Connect cable sections or provide branching points.

Vibration Dampers: Reduce aeolian vibrations and mechanical fatigue on the cable. Downlead Clamps: Guide the cable from the tower to ground or equipment. Cable Trays and Repair Rods: Facilitate installation and maintenance.

Aircraft Warning Spheres and Bird-

Scaring Devices: Enhance safety and prevent wildlife interference. Standards and PerformanceOPGW fittings are manufactured according to international standards such as IEC 61284, IEC 61897, IS 2486, ANSI, and DIN. They are type-tested for: Ultra-high voltage: AC 1000 kV, DC ±1100 kVUltra-long spans: up to 2,756 mExtreme temperatures: down to -60℃Heavy ice loads: up to 60 mm These fittings are tested by recognized institutions like KINECTRICS, CEPRI, and SECRI to ensure reliability under mechanical, electrical, and environmental stresses.
