Frequently Asked Questions (FAQ)
What is the purpose of a Preformed Suspension Clamp?
A preformed suspension clamp is used to secure steel core aluminum conductors (ACSR) to suspension insulators. It distributes static and dynamic stresses uniformly, protecting the conductor from vibration fatigue and mechanical wear.
How do I choose the correct model for my conductor?
You should match your conductor's outer diameter with the "Applicable Conductor Diameter Range (Min - Max)" listed in the specification table. Additionally, ensure the Vertical Breaking Strength meets your line design requirements.
What do the color codes represent in the specification table?
The color codes are used as a quick visual identification system during field installation. They ensure that operators install the correct clamp size corresponding to the matching conductor diameter.
What is the "Vertical Breaking Strength" and why is it important?
Vertical Breaking Strength (measured in kN) indicates the maximum vertical load capacity the clamp can handle before structural failure. It is critical for ensuring safety under extreme environmental loads like wind and ice accumulation.
Are custom specifications available if my conductor size is not in the table?
Yes. The specification table covers our standard production line. If you require custom cleat lengths, weights, or compatibility with non-standard conductor diameters, please contact our team directly for custom solutions.
