    Abstract: The elastic isolation element (10) has a strip-shaped metal spring core (11) that is enclosed on all sides by a casing (12) of insulating material. The core consists of a nonmagnetic, sprung metal, pref. a stainless steel. Its thickness is a few mm., pref. 2 or 3 mm. The core has an arrangement for limiting induced eddy currents. An Independent claim is also included for an application of an isolation element for wedging a coil in the groove of a plate packet.

    Abstract: In order to limit overload currents in electric lines, caused by a short circuit for instance, the invention calls for a current limiter to be inserted in the electric line to limit the overload current to a given multiple of the nominal current. The simple, compactly designed current limiter has, disposed on each side of a disc-shaped insulator (1), a composite conductor made up of a high-temperature superconductor (3, 3') and a normal conductor (4, 4') connected flat against each other to give good electrical contact. Between the composite conductors and the insulator (1) is a chemically insulating buffer layer (2) made of 2-.mu.m-thick silver. Either the superconductor side or the normal-conductor side of the superconductor makes flat contact with the insulator (1). The electrical resistance of the shunt (4, 4) should not be greater than that of the superconductor (3, 3') connected to it. Each composite conductor is meander-shaped in design and electrically connected so that the current in adjacent strips of the composite conductor flows in opposite directions.

    Abstract: PCT No. PCT/CH95/00215 Sec. 371 Date Jul. 30, 1996 Sec. 102(e) Date Jul. 30, 1996 PCT Filed Sep. 25, 1995 PCT Pub. No. WO96/10269 PCT Pub. Date Apr. 4, 1996A current limiting device including at least one superconductor and at least one nonsuperconducting shunt resistor in parallel with each superconductor. Each superconductor has a first main superconductor face in contact with a main shunt resistor face of a shunt resistor so as to form a compound conductor generally in the form of a meandering band having a band width greater than approximately 3.5 times the superconductor thickness. At least one insulator has opposing faces each in contact with a compound conductor. Multiple compound conductors are arranged such that current flows in opposite directions through adjacent compound conductors.

    Abstract: A coil rod (10) for a high-tension coil such as a stator coil in an electrical machine includes many conductors (13) fitted over or alongside each other forming a rectangular cross-section of conductors enclosed by insulation (14). Without changing the insulation thickness, electrical consistency on the edges is improved if the insulation thickness (d2) on the edges (15) of the coil rod is greater than the insulation thickness (d1) on the coil rod's flat sides.

    Abstract: The stator winding insulation uses a mica band (11) with a carrier layer (4) provided with longitudinal and transverse threads (7a,7b), to which a layer (5) containing mica and a binder material is applied on at least one side. The volume ratio between the longitudinal threads and the transverse threads in the carrier layer is at least 2.5 : 1, the applied layer containing fine mica particles with a high packing density. The weight ratio of the mica particles to the carrier layer within the mica band is 6 or above.
