Title: Yasuhiro Hagiuda: Innovator in Insulating Polyolefin Laminated Paper
Introduction
Yasuhiro Hagiuda is a notable inventor based in Shizuoka, Japan. He has made significant contributions to the field of materials science, particularly in the development of insulating polyolefin laminated paper. With a total of 4 patents, Hagiuda's work has implications for various applications, including electric power supply cables.
Latest Patents
Hagiuda's latest patents focus on methods for producing insulating polyolefin laminated paper. One of his innovations involves a process where first and second fiber paper layers are laminated to a polyolefin film layer. The fiber paper layers exhibit an impermeability of 20 to 4000 Gurley-seconds. Notably, at least one of the fiber paper layers undergoes mechanical deformation to create irregularities with a depth of 2 to 50% of the thickness of the layer. This mechanical deformation occurs prior to lamination, and the water content of the fiber paper layers is controlled to be no more than 4%. The thickness of the fiber paper layers is preferably at least 30 microns. Additionally, an electric power supply cable incorporates this insulating polyolefin laminate paper as an insulating layer.
