1. Definition

Preformed tension clamp, also known as terminal spiral clamp or preformed tension clamp, is a device used to fix cables (such as ADSS, OPGW, etc.) to poles and towers. It is widely used in communication optical cables and power transmission lines to ensure that the cables remain stable during installation and operation.

2. Material

Aluminum-Clad Steel Wire: combines the high strength of steel and the corrosion resistance of aluminum, suitable for harsh environments.
Galvanized Steel Wire: has high strength and good corrosion resistance, widely used in overseas projects.

3. Function

It is used to safely connect cables to poles and towers to prevent cables from loosening or being damaged by external forces such as wind and ice load during operation. Its design can evenly distribute the stress on the cable and reduce local stress concentration, thereby extending the service life of the cable. In communication optical cables, prefabricated tension clamps ensure that the cable is not damaged during transmission and ensure stable signal transmission.

4. Type

Single Grips: Suitable for ADSS cable installation with short spans (less than 100 meters).
Double Grips: Suitable for medium and long span (over 200 meters) ADSS cable installation.
Big Grip Dead End: Suitable for long span (over 800 meters) cable installation.

5. Technical Specifications

The size of the tension clamp needs to match the conductor diameter to ensure a tight fit. Choose the appropriate tension clamp type according to the distance between the poles and towers. Factors such as temperature, ice load and wind speed will affect the material selection and design of the tension clamp.

6. Installation and Maintenance

The installation process of prefabricated tension clamps is relatively simple and usually does not require complex tools. Its corrosion resistance and high-strength design reduce maintenance requirements, but regular inspections are still required in harsh environments.

7. Customized service

Due to different standards and requirements in different countries and regions, Handan Jinmai Fastener Manufacturing Co., Ltd. provides customized services to meet the needs of specific projects.
