Figure-8 and ADSS Cable Tension Clamp PA-27
The PA-27 tension clamp secures and tensions the messenger of figure-8 cables or round ADSS cables on outdoor aerial telecommunications lines.
Features
- Automatically adjusting wedge grip
- Installation without additional tools
- Durable UV-resistant thermoplastic body and stainless steel bail
- Holds the cable without slipping or damaging its insulation
- Fits pole brackets and hooks
- Stable performance in outdoor conditions
- Economically priced
Application
The PA-27 tension clamp attaches to utility poles, wall brackets, pole hooks and similar supports to form terminal or intermediate anchor points on overhead cable routes. Applications include urban communications, residential broadband, rural network extensions, industrial sites, campuses and public utility networks.
It maintains line tension while protecting the cable jacket against slipping, excessive compression and mechanical stress. Its automatically adjusting wedges can be fitted without specialist tools, reducing installation time and labor costs.
A UV-resistant thermoplastic body and stainless steel bail provide resistance to sunlight, rain, moisture, temperature changes and corrosive conditions. This construction supports use in coastal, mountainous and other demanding outdoor locations.

Ultimate tensile strength testing evaluates a product’s capacity to withstand mechanical pulling loads. Opposing tensile forces are applied to a specimen until it deforms or fails. The resulting measurements provide information on elongation, yield point, tensile strength and ultimate strength.
JKTE uses tensile testing for pole-line suspension clamps, preformed guy grips, ADSS dead-end fittings, stainless steel bands, FTTH drop clamps and tension clamps.
For overhead optical cables and their accessories, endurance testing combines mechanical and thermal loading with oscillating stresses. The applicable test values depend on the requirements of IEC 61284.
These standard-based tests are applied before new products are released and during routine production to check conformity with quality requirements. JKTE’s in-house laboratory carries out the relevant series of type tests.
