3results about How to "Reduce insulation thickness" patented technology

The present disclosure provides "Asymmetric wire insulation for traction motor stators." A stator assembly is presented. The stator assembly includes a stator core defining slots and magnetic wires positioned within the slots. Each magnetic wire includes a conductive core and an insulation layer surrounding the core. The insulation layer can have a varying thickness, with thinner portions spanning certain sides of the wire and thicker portions spanning other sides.

This invention relates to a wide-width high-temperature carbonization furnace, belonging to the technical field of carbon fiber production equipment. The furnace chamber of this invention has an arched top plate, and the connection between the arched top plate and the side plates is a sliding groove engagement. The furnace body contains an ash accumulation chamber, a graphite scraper capable of completely covering the ash accumulation chamber, and a graphite scraper driving mechanism. The ash accumulation chamber is connected to injection and suction ports located on both sides of the furnace body. The arched top plate of this invention, which is slidably supported by the side plates, provides strong structural stability. Furthermore, the movable graphite scraper and ash accumulation chamber within the furnace allow for automatic cleaning of the furnace without shutting down the production line.

The invention belongs to the technical field of superconducting, and relates to an insulation enhanced superconducting cable and a preparation method thereof. The method comprises the following steps: firstly, reinforcing a superconducting wire rod through a NiCoCr / Cu composite matrix, and carrying out multi-channel coating and on-line monitoring by adopting BN modified polyimide paint to form a uniform insulating layer; and then wrapping and hot pressing are carried out by using a B-stage epoxy-impregnated aromatic polyamide tape to construct an insulation enhanced structure. Stranded cable forming is carried out through tension control and a numerical control positioning die, and the composite cable is formed by combining the core wire and the multiple layers of insulation reinforced wires. Finally, through secondary wrapping and pretension braiding protection, the superconducting cable with the coverage area larger than or equal to 99.9% and the void ratio smaller than 1% is obtained, the withstand voltage between strands is larger than 5000V, the withstand voltage between cables is larger than 7000V, the mechanical stability and the thermal management performance are remarkably improved, and the superconducting cable is suitable for being applied to high-field magnets and fast pulses.
