Advancing Electrical Utility Reliability Through Innovative Engineering and Manufacturing
The electrical utility industry depends on equipment that performs flawlessly in some of the world’s harshest environments. From coastal substations to high-voltage transmission networks, every component must withstand extreme weather, corrosion, electrical stress, and decades of continuous service. At Inter-Ion, Inc., we partner with leading electrical utility manufacturers to engineer, redesign, and manufacture innovative solutions that improve reliability, extend service life, and enhance worker and public safety.
With over 30 years of manufacturing experience in Northeast Ohio, Inter-Ion provides complete engineering, precision manufacturing, advanced coatings, and production support for customers throughout the electrical utility industry.
Extending the Life of Vacuum Switches
One of Inter-Ion’s most impactful projects involved redesigning components for electrical Vacuum Switches (VSVs) used on utility poles.
Field technicians rely on these switches to quickly determine whether electrical circuits are open or closed during maintenance operations. Existing designs presented visibility challenges, making inspections extremely time-consuming.
Our engineering team developed a new indicator window that provides a clear visual confirmation of the switch position, allowing maintenance personnel to verify operating status more quickly and confidently.
Beyond improving visibility, we addressed another significant challenge affecting utilities operating in highly corrosive environments.
Solving Corrosion in Coastal Installations
Utilities located near oceans and other corrosive environments experienced premature failure of the steel brackets supporting the vacuum switches. Corrosion frequently developed where welded brackets met the support posts, reducing service life and increasing maintenance costs.
Inter-Ion engineers:
- Redesigned the affected components while maintaining all original operating specifications.
- Integrated the improvements into the existing switch assembly without affecting functionality.
- Applied a specialized sacrificial protective coating to the welded bracket interface.
- Increased component durability in aggressive environmental conditions.
The result was a significantly longer operating life for the vacuum switch assemblies while reducing maintenance requirements for utility providers.
Redesigning High-Voltage Insulators for Improved Safety
High-voltage ceramic and porcelain insulators are exposed to tremendous electrical and environmental stresses. Sudden voltage changes caused by lightning strikes can generate rapid thermal expansion within traditional ceramic components, potentially leading to catastrophic failure.
When ceramic insulators fracture, the resulting fragments can become dangerous projectiles, creating safety risks in populated areas.
Inter-Ion partnered with a Fortune Global 500 company to completely redesign these critical components.
Engineering a Better Insulator
Rather than relying solely on traditional ceramic construction, our engineers developed an improved design incorporating specially formulated silicone rubber while maintaining all required electrical performance characteristics.
The redesigned insulator maintained:
- Arc resistance
- Wet tracking resistance
- Electrical insulation performance
- Electrostatic characteristics
- Mechanical durability
One of the most difficult engineering challenges involved bonding silicone rubber to aluminum and copper support rods.
Our team developed a specialized plating process that prepared the metal surfaces for superior rubber adhesion, ensuring long-term durability under demanding operating conditions.
The result was a safer, more reliable insulator capable of delivering the required electrical performance while significantly reducing the risks associated with ceramic failure.
Precision Manufacturing of Bird Guards
Bird guards play a vital role in protecting electrical transmission infrastructure by preventing wildlife from contacting energized components.
Inter-Ion engineered a custom vinyl dipping process to manufacture bird guards with consistent quality and dimensional accuracy.
The project required designing an entirely new dipping system capable of producing complex geometries while maintaining precise coating thickness.
Our engineers overcame challenges including:
- Controlling withdrawal speed during vinyl dipping.
- Achieving uniform film thickness across the entire component.
- Eliminating wave effects during curing.
- Producing repeatable, production-ready parts.
The finished bird guards met demanding utility industry quality standards while providing dependable long-term protection for transmission equipment and saving wildlife.
