The Aluminum Alloy Tension Clamp is designed for anchoring and tensioning 4-core aerial bundled cable (ABC) in low-voltage overhead distribution networks. Built with a high-strength aluminum alloy body and weather-resistant fastening components, this clamp provides secure cable retention over span lengths while helping protect the insulated messenger and conductor surface.
Its preformed wedge-style structure allows quick installation without complex tools, making it suitable for utility poles, wall-mounted hooks, standard brackets, and pigtail fittings. The clamp is developed for reliable holding force in demanding outdoor environments, including rain, wind, heat, and cold. Its lightweight but durable construction also simplifies transport, site handling, and installation work.
The TX-PA4 series is available in several size ranges for different conductor sections, including common 4 × 16–35 mm², 4 × 16–50 mm², 4 × 50–120 mm², and similar low-voltage ABC applications. Depending on model selection, the clamp body may be paired with nylon wedges, galvanized steel hardware, or equivalent weather-resistant components to deliver stable mechanical performance and long service life.
This clamp is widely used for dead-end, anchor, and strain connection points in aerial bundled cable systems where dependable tension holding and easy field installation are required.
International Standard Compliance
The TX-PA4 Tension Clamp is manufactured according to recognized utility hardware quality and performance practices.

Construction & Materials
The TX-PA4 clamp is manufactured using durable materials chosen for mechanical strength, corrosion resistance, and stable outdoor performance.
Typical construction includes:
- Clamp body: High-strength aluminum alloy
- Wedge/insert: Engineering polymer or nylon, depending on model
- Bail/hook interface: Galvanized steel or equivalent corrosion-resistant metal
- Fastening hardware: Hot-dip galvanized steel where applicable
- Cable contact area: Designed to grip securely while reducing surface damage to the insulated messenger or conductor
Its preformed and wedge-operated structure supports a strong holding force while maintaining practical installation convenience for overhead ABC line work.
Installation Guide
- Confirm the cable type, conductor range, and required mechanical load before selecting the correct TX-PA4 model.
- Check the bracket, hook, wall anchor, or pole fitting to ensure compatibility with the clamp bail.
- Open or prepare the clamp according to the wedge design.
- Insert the ABC cable into the clamp body in the proper position.
- Ensure the messenger or supported section is seated correctly inside the gripping zone.
- Allow the wedge section to lock the cable naturally or tighten as required by the model structure.
- Attach the clamp bail to the hook, bracket, or pigtail support point.
- Verify that the cable is aligned properly and that the clamp is holding the required tension.
- Inspect the insulation surface to confirm it is not cut, pinched, or excessively compressed.
- Complete final line tensioning and recheck installation security.
Installation Note:
For best performance, always match the clamp size to the cable diameter and cross-sectional range. Use only on suitable low-voltage ABC applications according to project design.
