Model Number Explanation:
- C = Suspension clamp
- L = Preformed spiral type
- The numbers = Applicable conductor model
Frequently Asked Questions (FAQ)
What standard do these preformed suspension clamps comply with?
These clamps correspond to the industry standard model GB/T 1179-83 (specifically the LGJ/LGJF Series) designed for steel core aluminum conductors.
How do I interpret the model numbering system?
In the model code, "C" stands for Suspension clamp, "L" stands for Preformed spiral type, and the following numbers represent the applicable conductor model.
What is the purpose of the color code in the specifications?
The color code (e.g., Red, Yellow, Blue, Pink) is used to easily identify the specific clamp size and correspond to the matching conductor diameter range during installation.
What is the vertical breaking strength of these suspension clamps?
Depending on the model, the vertical breaking strength ranges from 66 kN for smaller conductor models (such as CL-35 to CL-185) up to 111 kN for heavy-duty models (such as CL-400 to CL-800).
Can I order custom specifications not listed in the table?
Yes. The specification table lists only partial products. For customized specifications or other conductor configurations, please contact our support team directly.
