The DIMI ADSS Tension Clamp is an anchoring assembly for All-Dielectric Self-Supporting (ADSS) fiber optic cable. It secures the cable at a tension point and transfers the applied cable load to the supporting pole or tower through the clamp assembly and its connection hardware.

Cable Gripping Design
Preformed Gripping
Preformed armor rods extend along the ADSS cable to form a defined gripping section, with the rod geometry corresponding to the specified cable and clamp configuration.
Mechanical Gripping
Mechanical versions use wedge or bolted gripping components to retain the ADSS cable within the clamp body, with the gripping parts matched to the specified product configuration.
Cable Matching
The gripping arrangement is selected according to the cable outside diameter and applicable cable construction, so the supplied clamp corresponds to the specified cable rather than relying on a generic clamp size.
Mechanical Design
The clamp establishes a defined contact relationship between the gripping components and the ADSS cable, with the contact geometry determined by the selected cable and clamp configuration.
Grip Load Distribution: In preformed configurations, the extended armor-rod section distributes the gripping action along the designated cable contact length instead of relying on a single short gripping point.
Mechanical Load Path: The applied cable tension passes from the gripping section into the clamp structure and then through the attachment arrangement, creating a continuous load path between the cable and the supporting structure.
Assembly Components
Gripping Components
The gripping elements provide the direct interface with the ADSS cable and vary according to whether the supplied configuration uses preformed or mechanical retention.
Connection Hardware
The attachment hardware forms the mechanical interface between the clamp assembly and the designated structural attachment point.
Complete Assembly
DIMI can supply the required gripping and connection components as one matched assembly when the project specification calls for a complete ADSS anchoring set.
Customization Services
Cable Configuration
DIMI can customize the clamp configuration according to the specified ADSS cable diameter and cable construction when the standard product range does not match the required cable specification.
Mechanical Requirement
The product configuration can be adjusted according to the specified mechanical load requirement when a project requires a configuration beyond the standard product range.
Connection Structure
The anchoring interface can be adapted when the required connection arrangement differs from the standard supplied configuration.
Quality Control
Dimensional Verification
Critical cable-gripping and assembly dimensions are checked against approved drawings or product specifications to verify conformity with the ordered configuration.

Dimension drawings can be provided for dimensional review, interface confirmation and project engineering approval where required.
Test Documentation
Applicable inspection or mechanical test documentation can be provided for the specified configuration when project procedures require documented verification.
FAQ
Q: What is the difference between an ADSS tension clamp and an ADSS suspension clamp?
A: An ADSS tension clamp retains the cable at an anchoring point under tensile loading, while a suspension clamp supports the cable at an intermediate point. Their mechanical functions are different.
Q: Can an ADSS tension clamp be used with any ADSS fiber optic cable?
A: No. The clamp must match the cable characteristics specified for the product configuration. The cable datasheet should be checked for outside diameter, construction and mechanical requirements.
Q: What should be checked before approving an ADSS tension clamp supplier?
A: Buyers should review the supplier's manufacturing capability, dimensional control, material control, mechanical testing capability and technical documentation for the specified configuration.
Q: What information should be included in an ADSS tension clamp RFQ?
A: An RFQ should state the required quantity, delivery requirements, cable information, mechanical requirements and connection requirements. A cable datasheet helps confirm the appropriate configuration.
Q: How can buyers verify an ADSS tension clamp before project approval?
A: Buyers can compare the proposed configuration with the project's technical requirements, cable specifications and dimensional documentation. Applicable test records can provide additional verification when required.
Q: What documentation may be requested for ADSS tension clamp procurement?
A: Documentation requirements vary by project and may include technical, dimensional, inspection or test records requested during supplier or product approval.
Q: How should an ADSS tension clamp be replaced when the original product is unavailable?
A: Replacement should be based on the original cable and anchoring requirements rather than visual similarity. The proposed replacement should be technically confirmed before approval.
Q: Can a manufacturer produce an ADSS tension clamp from an existing engineering drawing?
A: Yes. The manufacturer can review the drawing against the required dimensions and mechanical specifications to determine whether the requested configuration can be produced. Relevant cable information should also be provided if it is not defined on the drawing.
