Composite Suspension Insulator 515 mm by Eti-Polam, model 006638011

Composite Suspension Insulator 515 mm by Eti-Polam, model 006638011 is a suspension-type insulator designed for overhead power lines and electrical distribution systems. With a 515 mm overall length, this composite insulator provides insulation and mechanical support between conductors and supporting structures in outdoor installations where corrosion resistance and lower maintenance are required.

Advantages

The composite construction combines a fiberglass core with a polymeric housing to deliver high dielectric strength and improved mechanical performance compared with some traditional materials. Its lightweight design simplifies handling and installation while reducing load on supporting fittings. Weather-resistant polymer sheds offer protection against moisture and contamination, which helps maintain reliable insulation performance in outdoor environments.

Suitable for

• Suspension mounting on overhead medium-voltage lines
• Replacement of damaged or aged suspension insulators in distribution networks
• Outdoor installations exposed to corrosive environments
• Applications where reduced maintenance and improved contamination performance are needed

Key specifications

• Overall length: 515 mm
• Design: suspension composite insulator with polymeric housing
• Intended use: overhead power lines and electrical distribution systems
• Environmental resistance: enhanced resistance to corrosion and contamination typical for polymer insulators
• Mechanical characteristics: lightweight construction that reduces mechanical load on supports

How to use

Install the suspension insulator following applicable national and local electrical standards and the utility's installation procedures. Ensure that the mounting hardware and fittings are compatible with a suspension-type insulator and rated for the intended mechanical loads. Verify correct orientation and secure mechanical connections; confirm electrical clearances before energizing the line. Use appropriate personal protective equipment and de-energize circuits when performing installation or replacement work.

Usage recommendations

For reliable long-term performance, perform periodic inspections for mechanical damage, housing surface contamination, and secure fittings. Clean contamination according to accepted utility procedures when necessary, and replace the insulator if any structural damage or compromised mechanical strength is detected. Use compatible end fittings and torque values specified by the hardware manufacturer to ensure secure mounting.
