    摘要: An electrical apparatus is provided that has an electrical device encapsulated in a plastic encasement. The encasement includes an inner shell and an outer shell. The inner shell has a thickness greater than the outer shell and the inner shell is more flexible than the outer shell. The inner shell is formed from a first resin composition that, when cured, has a tensile elongation at break of greater than 5% and the outer shell is formed from a second resin composition that, when cured, has a tensile elongation at break of less than 5%.

    摘要: A power switching device for use in a power distribution network has a conductive element that is shaped in a non-cylindrical form. The non-cylindrical shape of the conductive element allows the non-conductive material such as epoxy that is used to form the body of the device to securely fasten the conductive element in place to thereby keep the conductive element from rotating when excessive rotational force is applied to the conductor. The conductive element can be shaped with a protrusion or in a C-shape. The protrusion and C-shape help prevent rotation of the conductive element when a threaded bolt is applied to secure a power cable to one end of the conductive element.
