Latest Patents

Wakamatsu’s listed patents address ways to integrate current-limiting components into insulator structures.

- **Suspension-type line arrester.** This invention describes an arresting insulator with an insulating body and a nonlinear resistor. The body has a head for linking the insulator to an adjacent insulator and a shed formed integrally with the head. The resistor is secured within the body and has a nonlinear relationship between residual voltage and current.

- **Lightning-conducting insulators.** This patent describes an insulator body with a shed, internal ribs, and a cup-like cylindrical head, together with a metal cap and pin. A cylindrical fitting section in the shed contains a current-limiting element with a nonlinear voltage-current characteristic. Glass- and ceramics-bonding metal solder seals the fitting section and the element’s end faces.
