## Summary description

Composite tension insulator ENSTO SDI90.150 rated for 12–14 kV systems with 70 kN mechanical strength. Designed for overhead line guying and conductor suspension, it features oval eye fittings for secure connections. Suitable for medium-voltage distribution networks, this insulator provides mechanical support and electrical insulation in outdoor utility applications.

## Long description

The ENSTO SDI90.150 composite tension insulator is designed for medium-voltage overhead lines operating at 12–14 kV. Built to provide both mechanical support and electrical insulation in outdoor utility applications, this insulator is intended for guying and conductor suspension where a rated mechanical strength of 70 kN is required. The composite construction offers a compact, lightweight alternative to traditional ceramic insulators while maintaining stable performance in varying weather conditions. Oval eye fittings at each end provide secure, aligned connections to hardware and ensure straightforward integration with common line fittings.
Advantages
The composite material reduces weight and handling difficulty compared with heavier insulators, making installation and replacement faster and safer. Hydrophobic housing improves pollution performance and reduces surface leakage under wet conditions. Oval eye fittings provide reliable mechanical coupling and minimize hardware rotation under load. The design is intended for long service life with low maintenance needs in outdoor medium-voltage distribution networks.
Suitable for
Overhead line guying and stay assemblies on 12–14 kV networks
Conductor suspension points requiring 70 kN mechanical strength
Medium-voltage distribution lines in urban and rural outdoor environments
Replacement of ceramic or glass tension insulators with composite alternatives
Key specifications
Rated system voltage: 12–14 kV
Mechanical tensile strength: 70 kN
Insulator type: composite tension insulator
End fittings: oval eye fittings at both ends for secure connections
Recommended application: outdoor overhead line guying and conductor suspension
How to use
Install the insulator in accordance with local electrical codes and utility practice. Secure the oval eye fittings to matching line hardware using appropriate pins or shackles rated for the specified mechanical load. Ensure correct orientation and alignment of the insulator to avoid bending forces on the eyes. Verify that clearances meet safety requirements for 12–14 kV systems and that adjacent components are compatible with composite materials. Perform mechanical and visual checks after installation and periodically during service life.
Usage recommendations
Use compatible stainless-steel or galvanized fittings to avoid galvanic corrosion. Avoid exposing the composite housing to sharp objects or concentrated mechanical stress during handling. For polluted environments, consider periodic inspection and cleaning to maintain hydrophobic performance and electrical insulation levels.
