Socket clevises attach insulator strings and suspension hardware to support structures in overhead power distribution systems. The clevis body features a socket at one end and uses a threaded bolt or pin for secure connections to poles and towers, providing stable attachment points essential for electrical grid reliability.
Constructed from high-strength ductile iron or steel with hot dip galvanized coatings, socket clevises resist corrosion in outdoor environments. Rated loads typically range from 30,000 to 50,000 pounds, with breaking strengths of 70 kN, 120 kN, or 160 kN depending on transmission line requirements. Common models comply with ANSI class 52-3, 52-5, or IEC 16mm standards.
The assembly includes the clevis body, anchor shackles secured with clevis pins and bolts, and fasteners such as nuts and cotter pins. Manufacturing involves casting molten iron into molds, followed by annealing to improve strength and ductility, then hot dip galvanization at approximately 449 degrees Celsius to apply protective zinc coating.
Installation requires assembling insulator strings on the ground before elevation to support structures, using standard tools and proper alignment techniques. Socket clevises accommodate various insulator sizes and support structure types, including wooden, concrete, and steel poles, making them versatile components for power distribution and transmission applications.

Frequently Asked Questions (FAQS)
What is a Socket Clevis and what is its primary function?
A Socket Clevis is a hardware component used in overhead power distribution systems to connect insulator strings or suspension hardware to support structures such as poles or towers. It links the tension clamp and socket type insulator, ensuring secure attachment and proper alignment in transmission lines, overhead lines, and power lines. It can also serve as an electric link for supplying energy to trains, trolley buses, and trams.
What materials are Socket Clevises made from and how are they protected?
Socket Clevises are made from high-strength materials such as ductile iron or steel and are hot-dip galvanized for durability. The galvanization process coats the component in molten zinc, providing excellent resistance to corrosion and rust, extending service life in outdoor environments.
What are the key features of Socket Clevises?
Key features include durable construction from high-strength materials, corrosion resistance through galvanization, secure attachment design, versatility for various support structures like wooden poles, concrete poles, and steel towers, easy installation with standard tools, adjustability for precise alignment, and compatibility with a wide range of insulator sizes and types.
What is the typical breaking load for Socket Clevises?
The breaking load varies by model and application, with common ratings including 70 kN, 120 kN, 160 kN, or in pounds, such as 30,000 lb, 50,000 lb, depending on the insulator class and design specifications.
How are Socket Clevises installed?
Socket Clevises are designed for easy installation using standard tools and equipment. It is recommended to assemble insulator strings on the ground before installation on poles or towers. The process involves securing the clevis to the support structure and attaching the insulator strings, ensuring proper alignment and tensioning of conductors.
