  • Patent number: 9991027
    Abstract: An electric wire includes a conductor having a cross-sectional area of not less than 225 mm2 and not more than 275 mm2, an insulation provided so as to cover the outer periphery of the conductor, and a wire sheath provided so as to cover the outer periphery of the insulation. The amount of deflection is not less than 130 mm when, at 23° C., one end of the electric wire is fixed to a fixture table so that another end horizontally protrudes 400 mm from the fixture table and a weight of 2 kg is attached to the other end, and cracks and breaks do not occur when wound with a bending diameter of three times the diameter at ?40° C.

  • Patent number: 8816209
    Abstract: A submersible motor electric wire includes a conductor including a copper wire and an enamel coating formed on the periphery of the copper wire, and an insulating sheath layer formed outside the conductor. The insulating sheath layer includes a silane graft polymer as a main constituent. The silane graft polymer is formed by a graft-polymerization that an unsaturated silane compound and an organic peroxide are added to polyethylene, and is cross-linked contacting with water in the presence of a siloxane condensation catalyst. Alternatively, the insulating sheath layer includes a composition including polyethylene as a main constituent, and the composition is cross-linked by being irradiated with an ionizing radiation.
