摘要： A gas-insulated bushing including an insulating tube filled with an insulating gas, a central conductor centrally arranged within the insulating tube, and a capacitor unit connected to the central conductor and partitioning the interior of the insulating tube. The central conductor has an intermediate constriction to which the capacitor unit is connected and is formed of two connected conductor parts, at least one of which is terminally restricted to form the constriction. A pair of flanges is secured to the ends of respective of the conductor parts and connects the conductor parts at the constriction. A shield member is supported on one of the flanges and spaced apart from the conductor parts at the constriction in order to relieve the electric field at the constriction.

摘要： A grain oriented electrical steel sheet comprises metal part containing Si: about 2.5 to about 5.0 mass % and Cr: about 0.05 to about 1.0 mass %, and an insulation coating formed on a surface of the metal part. A tension imparted to the metal part in the rolling direction by the insulation coating is not smaller than about 3.0 MPa. Magnetic flux density B8 satisfies a specific relation formula. A plurality of linear strains or grooves are formed in a surface of the steel sheet and linearly extended at an angle of not larger than about 45° (in each direction) relative to a direction perpendicular to a rolling direction such that an interval D of the linear strains or grooves satisfies a specific relation formula depending on the Cr content. A grain oriented electrical steel sheet is thereby obtained which has lower iron loss after domain refining treatment than conventional values. In the production process for the steel sheet of the invention, parameters such as annealing temperature in annealing before final cold rolling are controlled.

摘要： In a grain-oriented electrical steel sheet having phosphate-based coatings, which contain no chromium and which impart a tension, on the surfaces of a steel sheet with ceramic underlying films therebetween, the coating amount of oxygen in the underlying film is 2.0 g/m2 or more and 3.5 g/m2 or less relative to both surfaces of the steel sheet. Consequently, a grain-oriented electrical steel sheet with a chromium-less coating is provided. The resulting steel sheet has coating properties at the same level as those of a steel sheet with chromium-containing coatings and realizes high hygroscopicity resistance and a low iron loss without variations.
