Abstract: PROBLEM TO BE SOLVED: To provide insulative material of unchanging electric particle discharge adaptable to the environment and suitable for use at a relatively high temperature and under a high voltage. SOLUTION: Electric insulative material includes an insulation layer 10 and a polymer, particularly thermoplastic resin. The insulation layer 10 has mineral which has particle size particularly not more than 20 μm and is formed in a thin plate shape, particularly a micro mica thin plate 2. The micro mica thin plates 2 are laminated so that hollow parts are formed between the micro mica thin plates 2 and are substantially in parallel to the insulation layer 10. The polymer is permanently linked with the insulation layer 10 and the hollow parts 3 of the insulation layer 10 are filled with the polymer, and thus more uniform insulative material 1 can be obtained.

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.

Abstract: The hose has a glass fibre bundle (1), a tightly woven, inner glass fibre hose (2) enveloping the bundle, a flexible polymer coating (3) with rubber-elastic properties on the hose and a tightly woven outer glass fibre hose (4) enclosing the polymer coating. An Independent claim is also included for a method of manufacturing a strengthened, pressure-tight hose.

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.
