About Us

Started in Mountain View (California) in a small warehouse, IPI began with casting test-tube in plastic, then cutting them in half so the tubes could be checked for quality control.

Manufacture in USA

7000 sq ft facility in Sunnyvale, CA

In 1962 Ernie Bianco began the move into the epoxy resins IPI is using to make the High Voltage Bushings of today. He was joined by his brother and later his son, John Bianco, who continues to work for IPI. Lucile Bianco runs the front office today, making IPI a truly family business.

In 1986 IPI outgrew its shared location and made the move into the Sunnyvale address of today. IPI has grown into a custom manufacturing shop, with a complete High Voltage Bushing and Cable Connector Catalog.
