U-shaped tongue clips forged from carbon steel for composite insulators


Description :
Our hot-forged carbon steel U-shaped tongue clips are precision-engineered suspension components designed for composite polymer insulators in high-voltage transmission lines. These heavy-duty clamps provide secure mechanical anchoring while preventing insulator slippage, even under extreme wind and ice loads up to 100kN.


Key Features & Benefits :
✔ Superior Material - Forged from ASTM A105/A694 carbon steel with 345MPa yield strength
✔ Precision Fit - CNC-machined tongue-groove interface ensures ±0.2mm alignment accuracy
✔ Corrosion Protection - Standard hot-dip galvanizing (86μm) or optional Dacromet coating
✔ Load-Tested - 2.5x safety factor over rated mechanical load (RML) per IEC 61952
✔ Streamlined Design - U-shape reduces wind-induced vibration by 40% vs. traditional designs


Technical Specifications :

Parameter Specification
Material Grade A105, A694 F42-F60 (or equivalent)
Working Load 50-100kN (custom 150kN available)
Temperature Range -40°C to +120°C (high-temp versions to 200°C)
Surface Finish HDG (80-100μm), Dacromet, or epoxy coated
Standards IEC 61952, IEEE 1523, GB/T 2314


Applications :
• 110kV-1000kV transmission line dead-ends
• Railway catenary system suspensions
• Offshore wind farm insulator strings
• HVDC tower jumper supports


FAQ :

1. What makes your forged tongue clips superior to cast alternatives?

  • 3x Longer Fatigue Life: Forged grain structure withstands 1 million+ load cycles (per IEC 61325)

  • Higher Strength: 345MPa yield strength vs. 240MPa for typical cast steel

  • Precision Fit: CNC-machined grooves maintain ±0.2mm tolerance vs. ±1.5mm for cast parts

2. Which carbon steel grades do you recommend for different environments?

Grade Best For Coating Recommendation
ASTM A105 Standard terrestrial lines 86μm HDG
A694 F60 High-tension applications Dacromet + epoxy
Weathering Coastal areas Special alloy coating


3. How do you prevent insulator rubber damage?

  • Radiused Edges: 2.5mm minimum radius on all contact surfaces

  • Non-Mar Design: Electropolished grooves eliminate sharp edges

  • Load Distribution: Optimized U-shape reduces point loading by 60%

4. What testing do your clips undergo?

  • Mechanical:

    • 2.5x RML static load test (IEC 61952)

    • 50,000+ vibration cycles (IEEE 1523)

  • Environmental:

    • 3000hr salt spray (ASTM B117)

    • -40°C impact toughness test

5. What's your production lead time?

  • Standard: 4-6 weeks
