## Summary description

ENSTO SDI90.280 is a composite strain (tension) insulator designed for overhead line applications at system voltages of 24–36 kV. Rated for a 70 kN tensile load, it features oval-eye (ucho owalne) fittings for secure conductor and hardware attachment. Suitable for pole and tower line terminations and mid-span tension points where corrosion resistance and lightweight construction are required.

## Long description

ENSTO SDI90.280 is a composite strain insulator engineered for overhead distribution and medium-voltage power lines with system voltages of 24–36 kV. Designed to carry tensile loads up to 70 kN, this insulator uses oval-eye fittings for secure attachment of conductors and hardware. Its composite core and polymer housing deliver a corrosion-resistant, lightweight solution intended for pole and tower terminations as well as mid-span tension points where long-term mechanical performance and reduced maintenance are important.
Advantages
The composite construction provides high mechanical strength combined with low weight, improving handling and reducing loading on supporting structures. Polymer housing and seals offer resistance to environmental degradation and corrosion compared with traditional ceramic or glass alternatives. Oval-eye fittings enable reliable conductor clamping and hardware connection, simplifying installation and ensuring stable mechanical fixation under rated tensile load.
Suitable for
 Pole and tower line terminations on 24–36 kV overhead networks
 Mid-span tension points requiring a 70 kN rated tensile capacity
 Applications where corrosion resistance and reduced maintenance are desired
 Locations where lighter insulator weight is beneficial for handling or structural load limits
Key specifications
 Rated system voltage: 24–36 kV
 Nominal tensile load capacity: 70 kN
 Fitting type: oval-eye end fittings for conductor/hardware attachment
 Construction: composite core with polymer housing
 Typical applications: pole/tower terminations, mid-span tension points
How to use
Install the insulator according to industry-standard procedures for strain insulators on medium-voltage overhead lines. Verify compatibility of the oval-eye fittings with the selected hardware and conductors before tensioning. Mount the insulator securely to the support structure and apply tensile load gradually, observing alignment and hardware torque specifications. Inspect sealing interfaces and housing condition after installation and following initial tensioning to confirm correct assembly and absence of damage.
Usage recommendations
For reliable long-term service, select compatible stainless or galvanized connecting hardware sized for the rated tensile load and suitable for the local environmental conditions. Perform routine visual inspections to detect housing damage, tracking, or abnormal mechanical deformation, and clean contaminant build-up where necessary to maintain insulation performance.
