摘要： An insulating tape, for coating a connection portion of a power cable, includes a resin material which includes polyethylene at least partially modified by a molecule imparting hydrophilicity, an antioxidant, and a crosslinking agent. The antioxidant has a molecular weight in a range of 190 or more and less than 1050. The antioxidant has a content in a range of 0.05 parts by mass or more and 0.8 parts by mass or less, with respect to 100 parts by mass of the polyethylene. The insulating tape has a thickness in a range of 50 μm or more and 250 μm or less.

摘要： A copper-aluminum composite electric energy transmission system and a processing method therefor are disclosed. The system includes a copper terminal (1) and an aluminum cable (6). The aluminum cable (6) includes an aluminum conductor (2) and an insulation layer (3) cladding a periphery of the aluminum conductor (2). The system further includes an electric energy transmission aluminum piece (4), in which a section of the aluminum conductor (2) with the insulation layer (3) stripped from the aluminum cable is pressed to form a connecting piece. The electric energy transmission aluminum piece (4) and a front end of the aluminum conductor (2) form a molten layer (5). An end of the copper terminal (1) for being welded to the electric energy transmission aluminum piece (4) is provided with a welding platform (11). The molten layer (5) dads the welding platform (11) to form a transition layer (12) with metal atoms penetrating into or combined with each other. By reducing an internal stress between copper and aluminum, the mechanical property of a copper-aluminum welding joint is improved. Copper-aluminum compounds in the transition layer (12) are reduced, and the electrical property of the copper-aluminum welding joint is improved. Meanwhile, a path of the transition layer (12) to resist an erosion from an external environment is extended, thereby solving the metal corrosion problem of the copper-aluminum welding joint, and prolonging the service life.

摘要： Disclosed is a cable assembly including at least one conductor and a metal sheath disposed over the at least one conductor, the metal sheath including a continuous strip of metal having a plurality of revolutions. A first revolution of the plurality of revolutions may include a first section having a curved profile extending into an interior cavity of the metal sheath, and a second section extending from the first section, the second section extending along a lengthwise axis, wherein a length of the second section, along the lengthwise axis, is at least two times as large as a diameter of the first section when the metal sheath is in a linear configuration. The first revolution may further include a third section extending from the second section, the third section including a free end terminating within a recess defined by a curved profile of a first section of an adjacent revolution.

摘要： A cable with a signal detection function includes an insulating core, a second insulating layer, and a signal detection layer. The signal detection layer is for transmitting signal data. The cable further includes a second insulating layer, and plural signal detection layers provided for transmitting signal data. The signal detection layer and the insulating cores are disposed inside the second insulating layer, and the signal detection layer is cladded with plural insulating cores. If the first insulating layer in the signal detection layer is damaged, the signal detection layer will be electrically connected to the conductor assembly. The cable with the signal detection function can detect the abnormality of the insulating core through the signal detection layer to facilitate maintaining and repair the cable.
