High-strength forged galvanized wire sockets and U-shaped sockets for power infrastructure

Core Products :

• Forged Wire Sockets: Hot-dip galvanized connection terminals for ACSR/AAC/AAAC conductors
• U-Shaped Sockets: Heavy-duty forged anchors for dead-end and suspension applications

Key Features & Benefits :

1. Superior Durability
   • Material: High-carbon steel (C45/40Cr) or alloy steel forgings
   • Tensile strength: 600-800 MPa (custom grades available)
   • Impact resistance: Charpy V-notch ≥35J at -20°C
2. Advanced Corrosion Protection
   • Hot-dip galvanized coating (≥85μm per ISO 1461)
   • Optional duplex coating (galvanizing + epoxy) for coastal environments
   • Salt spray resistance >1,000 hours (ISO 9227)
3. Precision Engineering
   • Closed-die forging process ensures grain continuity
   • CNC-machined contact surfaces (±0.2mm tolerance)
   • Standard threads: M16-M64 (metric) or 5/8"-2-1/2" (UNC)

Technical Specifications :

Typical Applications :

• Overhead transmission lines (66kV-1000kV)

• Distribution network reinforcement

• Railway catenary systems

• Substation busbar supports

• Renewable energy grid connections

Product application :

1. Overhead Transmission & Distribution Lines

• Wire Sockets: Secure ACSR/AAC/AAAC conductors in tension and suspension systems (66kV–1000kV)

• U-Shaped Sockets: Anchor dead-end assemblies and jumper connections in high-voltage power lines

2. Railway Electrification Systems

• Connect and tension catenary wires for high-speed rail and metro power lines

• Withstand dynamic loads from pantograph movement

3. Substation & Switchgear Installations

• Support busbar systems and disconnect switches in harsh environments

• Provide reliable grounding connections for surge arrestors

4. Renewable Energy Grid Integration

• Wind Farms: Anchor offshore/onshore transmission line terminations

• Solar Plants: Secure conductor dead-ends in large-scale PV farms

5. Industrial Power Networks

• Heavy-duty applications in mining, oil & gas, and chemical plants

• Corrosion-resistant solutions for coastal and high-pollution areas

Why Our Products Stand Out :
✓ Longer Service Life: 30+ years in harsh environments
✓ Safety Focus: Fatigue-resistant design prevents stress cracking
✓ Global Compliance: Meet IEC, IEEE, and national grid standards
