4results 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 utility model discloses a miniaturized 10kV separable connector comprising a connector main body which is composed of an inner shielding layer, an insulating layer and an outer shielding layer. Through the optimized design of the shielding layer in the separable connector and the stress cone inner shielding layer, the electric field is uniform, the insulation thickness of the separable connector is reduced, the inner shielding layer, the insulation layer and the outer shielding layer adopt a three-layer injection molding process, the outer shielding layer and the insulation layer are tightly attached and are not easy to fall off, the resistance value is low, the shielding effect is good, and the service life of the separable connector is prolonged. And the structure is optimized and miniaturized, the overall weight of the product can be reduced, the withstand voltage level can reach 50kv, and the connector main body is made of ethylene propylene diene monomer rubber, so that the cost is greatly reduced.

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.
