    Abstract: A mold (1) for epoxy castings comprising a mold body (2), and a coating (3) covering the mold body (2). The coating (3) is made of multilayered thermoformable foil comprising at least an inner layer (4) and at least an outer layer (5) for being exposed to the epoxy resin during casting. The inner layer (4) is located between the mold body (2) and the outer layer (5), wherein the inner layer (4) fills the rough and porous surface of the mold body (2). Furthermore, the layers of the multilayered thermoformable foil being made of different kinds of polymers.

    Abstract: The present invention relates to a cooling apparatus for a medium voltage or high voltage switchgear, the cooling apparatus comprising:
    - an evaporator section;
    - a fluid conduit; and
    - a condenser section.
    The evaporator section is configured to surround at least part of a current carrying contact. The fluid conduit fluidly connects the evaporator section to the condenser section. A section of the fluid conduit is formed within the evaporator section and is electrically insulating and is configured such that fluid can contact an outer surface of the current carrying contact. The cooling apparatus is configured such that in use a working fluid in the evaporator section is heated to a vapour state, and the vapour is transferred by the fluid conduit to the condenser section. The vapour in the condenser section is condensed to the working fluid. The condensed working fluid is passively returned via the fluid conduit to the evaporator section.

    Abstract: The present invention relates to a switching self-sanitizing device which can be used in the environment where the users touch the device in order to change the status for open to close or vice versa. A switching self-sanitizing device comprising switching element (2) with an antibacterial coating (3) having an antibacterial agent in the structure of the coating (3), where the agent is activated by illumination of the coating (3) with an UV light source. The switching self-sanitizing device comprises a control box (8) mounted on the base plate (1) in which a microprocessor (13) and a converter (12) electrically connected with themselves are placed. The converter (12) is electrically connected with a proximity sensor (7) placed outside the box (8) on the front side of the plate (1). The proximity sensor (7) is electrically connected with the microprocessor (8) to which a switch element (14) is connected for closing or opening an illumination circuit which is powered through an internal plug (11) placed in a connection box (9) mounted on the plate (1). In the connection box (9) an external plug (10) is inserted for powering the microprocessor (8), the proximity sensor (7) and a the UV light source through the converter (12).
