CGU Type Suspension Clamp for Overhead Conductors
The CGU Type Suspension Clamp is an overhead line fitting designed for supporting conductors on transmission and distribution networks. It is commonly installed with insulator strings and suspension assemblies to maintain the correct position of overhead conductors.
The CGU series suspension clamp features a robust mechanical structure consisting of clamp body, keeper, fastening components, and connection parts. The commonly used design provides reliable conductor support for utility and power transmission projects.
Key Features
- Suitable for overhead transmission and distribution lines
- Designed for ACSR, AAC and AAAC conductors
- Malleable iron clamp body with galvanized steel hardware
- Hot-dip galvanized surface treatment for outdoor applications
- Multiple models available for different conductor diameters
- Reliable mechanical connection with suspension assemblies

Materials and Construction
The clamp body and keeper are commonly manufactured from malleable cast iron. Fasteners are produced from steel and protected with hot-dip galvanizing. Cotter pins are generally made from stainless steel for outdoor durability.
Surface Treatment
Hot-dip galvanizing is applied to ferrous components to improve corrosion resistance and suitability for outdoor power line environments.
Applications
- Overhead transmission lines
- Distribution networks
- Utility pole line projects
- Power infrastructure construction
Installation Guidance
The suspension clamp should be selected according to conductor diameter and installed following approved engineering drawings. Proper installation position and fastening requirements should comply with project specifications.
Quality Inspection
Typical inspection includes dimensional verification, appearance inspection, assembly checking, and mechanical performance testing according to manufacturing requirements.
Reference Standards
The product can be manufactured with reference to applicable overhead line hardware standards including IEC 61284. Reference to a standard does not constitute certification.
Ordering Information
