A removable weighted vehicle safety guard system having a safety attachment that removably attaches to the back end of a vehicle to add weight, thereby helping to keep the back end of the vehicle stabilized while driving in inclement weather or on slippery road surfaces, and additionally forms a brush guard to prevent damage to the vehicle should another vehicle rear-end the user's vehicle. The removable weighted vehicle safety guard system attaches to the back end of the vehicle via the hitch and is secured using bolts or trailer pins. The removable weighted vehicle safety guard system provides static weight to the back end of the vehicle but may optionally also receive additional if needed. The additional weight may take a number of forms, including weight blocks, and can be added to the removable weighted vehicle safety guard system via bolts or trailer pins.

The present invention relates to a transformer having a noise reduction structure. A tank (12) forms the exterior of the transformer (10). An inner space (14) filled with insulating oil is formed inside the tank (12). An iron core (20) is provided inside the tank (12) by a lower frame (16) and an upper frame (18), and coils (22) are wound around parts of the iron core (20) extending in the direction of gravity. An insulating sheet (24) is provided to encompass the surface of each of the coils (22), and has ridge portions (26) and groove portions (28), which are formed to extend in the height direction of the iron core (20). It is preferable that the side surfaces of the groove portions (28) are formed in parallel so as to face each other. The present invention as above minimizes the transfer of vibrations, generated from the coils (22), to the insulating sheets (24) provided on the surfaces of the coils (22) and removes a part of the vibrations since the vibrations coming out after having passed through the insulating sheets (24) are transferred to the insulating oil so as to cancel each other out. Therefore, the present invention can relatively reduce vibration and noise, which are generated from the transformer.

The mounting kit includes a first half shell and a second half shell for accommodating the toroidal core, a baseplate, and a latching means and/or guide means to connect the first half shell, the second half shell, the insulating element and the baseplate to one another.

In some embodiments, the instant invention can provide an electrical system that includes: a three-phase inductor with a core, including: a first segment having a first coil arrangement; a second segment having a second coil arrangement; a third segment having a third coil arrangement; where each of the first coil arrangement, the second coil arrangement, and the third coil arrangement has at least one air duct; at least one air baffle; and where the at least one air baffle is configured to be operationally attached to at least one selected coil arrangement in a position which allows the at least one air baffle to extend from at least one surface of the at least one selected coil arrangement into a flow of a supplied air.

The present invention provides an inductance coil comprising a magnetic core and a coil, wherein the coil is formed by winding a flat wire, and the flat surface of the wire is perpendicular to the axis around which the coil is wound. The coil is wrapped with an insulating adhesive tape and the tape is wound on the wire around an axis which is substantially in line with the direction along which the wire forming the coil extends, so as to form an isolation layer on the surface of the coil. Additionally, the present invention provides an electromagnetic device including the above inductance coil.
