Ensto SO274S Tension Clamp for 4x(35-50)mm2 Conductors

The Ensto SO274S tension clamp is a high-quality component engineered for the secure anchoring of self-supporting insulated conductor systems. Designed specifically for 4-core cables with cross-sections ranging from 35 to 50 mm2, this clamp provides the necessary mechanical strength to maintain tension in overhead power line installations. Its robust construction ensures long-term stability and reliable performance even when exposed to demanding environmental conditions, making it an essential element for professional electrical infrastructure projects.

Advantages

This tension clamp offers exceptional durability and resistance to harsh weather conditions, ensuring a long service life in outdoor environments. Its design facilitates quick and efficient installation, reducing labor time during the setup of overhead power lines. By providing a secure grip on insulated conductors, it prevents slippage and maintains consistent tension, which is critical for the safety and integrity of the electrical network. The materials used are specifically chosen to withstand mechanical stress and environmental degradation, providing a reliable solution for utility providers and electrical contractors.

Suitable for

• Anchoring self-supporting insulated conductor systems
• Overhead power line installations
• Professional electrical infrastructure projects
• 4-core cable tensioning for 35-50 mm2 cross-sections

When it may not be suitable

This clamp is not intended for use with cable sizes outside the specified 35-50 mm2 range, as this may compromise the mechanical grip and safety of the installation. It is also not designed for applications involving bare conductors or non-insulated cable systems.

Key specifications

• Compatible conductor type: 4-core self-supporting insulated cables
• Conductor cross-section range: 35-50 mm2
• Application: Overhead power line anchoring
• Material: Weather-resistant, high-strength components

How to use

To install the Ensto SO274S, ensure that the cable is properly prepared according to standard electrical safety procedures. Position the clamp onto the insulated conductor, ensuring the cable is seated correctly within the gripping mechanism. Apply the necessary mechanical tension as required by the project specifications, ensuring the clamp is securely locked in place. Verify that the installation is aligned correctly with the support structure to prevent unnecessary stress on the hardware.

What to consider before purchase

• Verify the exact cross-section of your conductor cables
• Ensure compatibility with your existing support hardware
• Check local electrical regulations for overhead line installations
• Confirm the quantity required for your specific project length

Usage recommendations

Always follow the manufacturer's installation guidelines and local safety standards when working with overhead power lines. Regular inspections are recommended to ensure the continued integrity of the tensioning system over time.
