Product introduction
The socket clevis, alternatively referred to as the socket tongue, is a critical component in the infrastructure of transmission lines, overhead lines, and power networks. This essential piece of pole line hardware serves as a connector between the tension clamp and socket-type insulator. Across various countries, the design and connections associated with socket clevises exhibit regional variations to meet specific requirements. For instance, in certain African applications, socket clevises are tailored for use with Aluminum Conductor Steel Reinforced (ACSR) cables exhibiting an outer diameter ranging from 7.00 mm to 18.2 mm (representing conductors from 25 mm² to 150 mm²). Moreover, they are compatible with standard disc insulators of the ball-and-socket type, characterized by a ball pin diameter of 16 mm.
FERR socket clevises are specifically engineered to connect insulator strings to transmission line components such as yoke plates and suspension clamps. Each unit is meticulously manufactured using forged steel to ensure precise dimensional tolerances. This guarantees optimal fitting and uniform stress distribution during operation.
The manufacturing process of FERR socket clevises predominantly employs cast iron and adheres to stringent procedural standards. Initially, the iron material undergoes heating from a solid to a liquid state. The molten iron is then carefully poured into molds designed to replicate the hollow geometry of the socket tongue. Once solidified, the cast is subjected to a subsequent annealing step to enhance material properties.
To ensure durability under extreme environmental conditions, the final step involves hot-dip galvanizing the socket tongue. This treatment effectively protects the component against corrosion, even in tropical climates characterized by humidity levels up to 90% and an average ambient temperature of +30°C. As a result, the socket clevis remains resistant to degradation despite prolonged exposure to harsh weather conditions.

sketch design stage
You only need to provide a sample or basic dimensions — our engineers will handle the rest. We turn your ideas into precise technical drawings based on a deep understanding of your actual needs, ensurinYou don’t need to prepare a full 3D model or detailed drawing.
3D modeling and production stage
We build high-precision 3D models based on the initial design, verifying every detail with professional software to meet production standards. Once approved, we move straight into precision manufacturing.
Testimonials
FERR always puts the interests of its customers first.
Yunex
Distribution network project contractors in Southeast Asia
I was most afraid of the drawings sent over to the docking is not clear, the results of FERR engineers directly with me to dock the technical details, and even the bolt hole spacing are confirmed to be very fine. Proofing out once through, no rework, too much trouble.
Orlando J.
Equipment distributors in Europe
Our customers are very picky, especially about the thickness and appearance of the hot-dip galvanized layer, and the goods sent by FERR not only meet the standard, but also the key is that each batch is very stable, and we have never had any problems with the secondary inspection.
Lambrinie
Procurement Manager, X Power Engineering, USA
We started out with just a couple samples to try, and they turned out to be so much better than what we were using before. The dimensional accuracy, surface finish are all spot on and the delivery was fast. Now every time I have a project I go to FERR first, with confidence.
Marco Martinez
Project Manager in the Middle East
I've used quite a few suppliers, some quotes are cheap but with lots of problems.FERR is not the cheapest but they are really the most hassle free. Design coordination, delivery time, packaging details can think ahead of me, I save a lot of energy.
Do you accept small orders?
Absolutely. Our minimum order quantity is 1 piece. You can order a small amount to feel the high quality of our products!
How long is your product warranty?
We offer a 2 years warranty on all our products
What’s your typical lead time?
Lead time depends on part complexity and order volume. For most prototypes or low-volume runs, we offer lead times as fast as 5–7 working days. Rush orders can often be accommodated.
Can I request a sample?
Yes. For Electric Power Fitting, we can provide first article samples upon request. Whether it’s sheet metal, CNC-machined, or assembled parts, we offer sample production to help you evaluate form, fit, and function before moving into full production.
What if the size does not match at the installation site?
We support customized service, in case of size inconsistency, you can contact your account manager at the first time. We will assist in confirming the cause of the problem and provide solutions such as modifying drawings, re-processing or replacing parts to ensure smooth installation of the product and reduce your time and cost loss.
How do you solve the problem of high mold cost and long delivery time?
We provide a variety of low-cost, fast delivery solutions, fusion molding, sand casting, disappearing mold, aluminum mold fast mold, mold sharing mechanism, as well as long-term cooperation mechanism with mold factories, to ensure that the opening of the mold is fast, save money, and do not affect the quality. For trial orders and small batch orders, we also offer flexible development programs to minimize the risk of upfront investment for our customers.
Do you provide type test reports or third-party certifications (e.g., IEC, ANSI)?
Yes. We can provide type test reports and third-party certifications upon request, especially for projects requiring compliance with IEC, IEEE, or national grid standards.
