Socket clevises are critical structural components in electric power transmission and distribution systems. This product series (including models such as WS-7, WS-10, W-7A, and W-7B) is designed to connect insulators to towers, extension links, or other line components, thereby enhancing electrical efficiency and minimizing line oscillation or displacement during operation.

Manufactured from high-quality, heat-resistant stainless steel with a galvanized finish, these components offer exceptional resistance to corrosion, weathering, salt spray, UV radiation, and temperature fluctuations, ensuring optimal performance in harsh environments such as coastal, desert, or remote areas.

Each unit is produced using advanced manufacturing techniques, combining high strength with excellent flexibility to effectively withstand conductor displacement and stress caused by moisture.

The socket interior is precision-molded to ensure a perfect fit with the insulator's ball stud, while the accompanying stainless steel locking pin securely fastens the connection to prevent displacement. The series is available in two configurations - the single-plate "W" type (W-7A, W-7B) and the double-plate "WS" type (WS-7, WS-10) - and comes complete with bolts and pins for rapid on-site installation. All products undergo chemical performance testing prior to shipment to ensure compliance with international electrotechnical standards. With advantages such as ease of installation, high safety, and long service life (durability), these socket clevis fittings are an ideal choice for overhead high-voltage line projects, power grid design, and substation construction.

Socket Clevis

1. High Mechanical Strength

Manufactured using high-quality steel and an integral forging process. Rigorous tensile load and breaking strength testing ensure stable load-bearing capacity. The design withstands variable loads caused by wind and conductor vibration, effectively preventing metal fatigue during long-term outdoor use.

2. Excellent Corrosion Resistance

Utilizes a high-quality galvanizing process to form a uniform, dense zinc coating. This coating resists rain, salt spray, UV radiation, and extreme temperature fluctuations, making the product suitable for high-voltage transmission lines in coastal, desert, and high-altitude regions.

3. Precision Ball-and-Socket Connection Design

The optimized ball-and-socket structure perfectly matches the insulator's ball stud. This connection allows for free angular rotation, effectively absorbing lateral forces and preventing damage to the insulator caused by line vibration. An included stainless steel pin provides dual anti-loosening protection, further enhancing operational safety.

4. Comprehensive Specifications and Easy Installation

Available in a wide range of specifications - including single "W" types (W-7A, W-7B) and double "WS" types (WS-7, WS-10) - and supplied with all necessary bolts and pins. Standardized dimensions simplify on-site installation and replacement for power infrastructure projects.

5. Strict Quality Control and International Standard Compliance

All products undergo rigorous inspection before leaving the factory and comply with international standards for high-voltage fittings. The products offer a long service life and low maintenance requirements, helping to reduce the overall investment cost of power transmission and distribution projects.

Question 1: What is the Minimum Order Quantity (MOQ) for socket clevis fittings?

Answer: Small-batch trial orders are accepted. The MOQ depends on the specific model. We offer highly competitive factory-direct pricing for large-volume orders. Samples are available for testing prior to formal procurement.

Question 2: What is the lead time?

Answer: Typically 10–15 working days after receipt of the down payment. For urgent projects, we maintain stock of common models (such as WS-7, WS-10, W-7A, and W-7B) to ensure rapid delivery.

Question 3: Can you provide mechanical performance test reports and certificates?

Answer: Yes. We can provide test certificates, material reports, and relevant documentation for tenders and customs clearance. We also accept third-party inspections upon customer request.

Question 4: What payment methods are accepted?

Answer: We generally accept T/T (bank wire transfer), with a 30% deposit required upfront and the balance payable before shipment. Payment terms for long-term partners can be negotiated separately.

Question 5: Can packaging and logos be customized according to customer requirements?

Answer: Yes. For large orders, we offer options such as custom logos, wooden pallet packaging, and specific shipping marks to ensure the packaging meets your project or tender specifications.
