Canada OPGW Fittings Single Mold

Single mold OPGW fittings, including U-bolt dead-end assemblies and tension clamps, are available in Canada from suppliers like Preformed Line Products, AFL Global, and GL FIBER, designed for secure and efficient optical ground wire installation.

Overview of Single Mold OPGW Fittings

Single mold OPGW fittings are specialized hardware used to terminate or secure Optical Ground Wire (OPGW) on transmission towers while protecting the optical fibers from stress and damage. These fittings typically include:

• U-Bolt Dead-End Assemblies: Designed to distribute axial and compressive loads along the OPGW cable, minimizing stress on the optical fibers. Retaining rods and wedges are used to secure the cable, and hardware components can be reused if in good condition. Custom options with left- or right-hand lay retaining rods are available, and accessories like anchor shackles or ground wire assemblies can be added based on catalog suffix codes (e.g., 2801304S2G) (Preformed Line Products) .

• Tension Clamps/Dead-End Fittings: Used to connect OPGW cables to tension-resistant towers, ensuring proper load transfer and vibration suppression. These clamps prevent harmful stress concentrations and maintain fiber integrity during installation and operation (GL FIBER) .

• Suspension Assemblies: Single or double suspension fittings are used to support OPGW cables along spans, reducing static and dynamic stress while maintaining proper bending limits (GL FIBER) .

• Downlead Clamps and Connector Kits: Downlead clamps guide OPGW from the tower to splice boxes, while connector kits (e.g., AFL Global Apex OPGW Connector Kits) provide secure, durable connections for optical fibers, often installed in pairs and compatible with a wide range of OPGW cables .

Key Features

• Durability and Corrosion Resistance: Many fittings are made from aluminum or stainless steel to match the expansion/contraction of the conductor and resist corrosion in harsh environments .

• Vibration Dampers: Tuned devices reduce fatigue caused by wind-induced vibration, protecting both the cable and the optical fibers .

• Ease of Installation: Single mold fittings are designed for straightforward installation with proper torque, minimizing fiber strain and ensuring long-term reliability .
