REVIEW

APPLICATION

This tension clamp is commonly installed on utility poles, wall brackets, pole hooks, and other supporting hardware to create dead-end or intermediate anchoring points along overhead cable routes. It is suitable for use in urban communication infrastructure, residential broadband installations, rural network expansion projects, industrial facilities, campuses, and public utility networks. The PA-37 clamp effectively maintains the required cable tension while protecting the cable jacket from damage caused by slipping, excessive compression, or mechanical stress.

Thanks to its self-adjusting wedge mechanism, the clamp allows quick installation without special tools, significantly reducing labor time and deployment costs. The UV-resistant thermoplastic body and stainless steel bail ensure excellent performance under harsh outdoor conditions, including prolonged exposure to sunlight, rain, humidity, temperature fluctuations, and corrosive environments. This makes the PA-37 particularly suitable for coastal areas, mountainous regions, and other demanding installation environments.

Test

Ultimate tensile strength test other called maximal mechanical tensile test which used to measure the ability to withhold mechanical loads of products.

This is a mechanical test where a pulling force is applied to a material from both sides until the sample changes its shape or breaks. It's is a common and important test that provides a variety of information about the material being tested, including the elongation, yield point, tensile strength, and ultimate strength of the material.

Jera proceed this test on below products

-Pole line suspension clamps

-Preformed guy grips

-ADSS strain dead ends

-Stainless steel bands

-FTTH drop clamps

-Strain clamps

Endurance test on failure tension testing equipment under mechanical and thermal stresses with oscillation stress has different values according to standard IEC 61284 for overhead fiber optic cable, and accessories.

We use following standards test on new products before launching, also for the daily production, in order to make sure ours customer could receive products which meet quality requirements.

Our internal laboratory is capable to proceed such a series of standard related type tests.
