Title: Eberhard Kertscher: Innovator in Electric Conductor Manufacturing
Introduction
Eberhard Kertscher is a notable inventor based in Romanel, Switzerland. He has made significant contributions to the field of electric conductor manufacturing, holding a total of six patents. His innovative approaches have advanced the technology used in insulated electric conductors and electric wire manufacturing.
Latest Patents
One of Kertscher's latest patents involves the manufacture of insulated electric conductors. In this process, a mixture of substances is fed to an extruder, where it is homogenized and liquefied before being extruded onto an electric conductor or as a pipe. The insulating material used is a polyolefin, such as polyethylene, which undergoes cross-linking through the addition of silane, a free-radical generator, and a silanol condensation catalyst. After extrusion, cross-linking occurs in the presence of moisture, facilitated by an agent that reduces the rate of crystallization of the polymer, such as vinyl acetate.
Another significant patent pertains to the method for manufacturing electric wire with wire-enamel-type insulation. This method involves forming an insulating sheath that adheres to the wire by extruding selected thermoplastics heated above their melting point. The extrusion apparatus includes a gauging die with a compressing cone, which has a specific aperture angle to ensure optimal performance.
