XG Suspension Clamp Handbag Type
Product Overview
The XG Suspension Clamp Handbag Type is a specialized suspension clamp designed for U-bolt type conductor suspension from insulator strings, providing secure retention with adjustable grip. Widely recognized in the industry under alternative names including U-bolt suspension clamp, U-type hanging clamp, this product serves as a critical component in overhead transmission and distribution lines systems.
Advantages
- “U-bolt retention” — adjustable U-bolt mechanism accommodates a range of conductor diameters within each model rated capacity
- “Strong forged body” — high-strength cast iron or steel construction withstands mechanical loads including wind, ice, and short-circuit forces
- “Conductor-friendly liner” — replaceable rubber or aluminum liner prevents surface damage and reduces vibration fatigue
- “Universal insulator fit” — ball eye or clevis connection matches standard suspension insulator strings
- “Ease of maintenance” — U-bolt can be retightened or replaced without removing conductor from the line

Material & Manufacturing
- Material: malleable cast iron or forged steel
- Secondary components: hot-dip galvanized finish with rubber/aluminum liner
- Surface treatment: Hot-dip galvanizing in accordance with ISO 1461 / ASTM A153 / IEC 61589, minimum zinc coating thickness 65 μm
- Manufacturing process: Precision forging, casting, or CNC machining of critical dimensions, followed by full galvanizing immersion. Dimensional accuracy controlled within ±0.5 mm tolerance on mounting interfaces
- Quality assurance: Every batch undergoes dimensional inspection, galvanizing thickness testing (magnetic or gravimetric method per ISO 2178), and visual surface examination. Mill test certificates (MTC) available upon request
Application Scope
- U-bolt type conductor suspension from insulator strings, providing secure retention with adjustable grip
- Overhead line suspension points on steel towers and concrete poles
- Long-span and heavy-load conductor support applications
- Distribution line crossarm and pole-top conductor hanging
Frequently Asked Questions
Q: When should I choose XGU over XJ? A: XGU is preferred when field adjustability of conductor grip is important, or when U-bolt tools are more convenient than keeper plate type XJ clamps.
Q: Can XGU clamps handle bundled conductors? A: Standard XGU clamps are for single conductors. For bundled configurations, use spacer clamps or custom multi-conductor suspension assemblies.
Q: What is the U-bolt torque requirement? A: Typically 20-40 N·m depending on model and conductor size. Follow the manufacturer specification to avoid over-compression.
