Abstract
The invention discloses a rare earth power cable, which comprises a cable core and a filling layer, wherein the cable core and the filling layer are wrapped with a wrapping tape layer, a shielding layer, an inner sheath, a metal armor layer, an outer sheath, a rare earth refractory layer and a rare earth water-blocking layer; shielding tapes are coated and lap-jointed with one another by means ofwave-shaped overlapping sections on two sides; armoring steel tapes are in lap joint with one another by means of steel tapes on two sides; rare earth aluminum alloy material of rare earth aluminum alloy conductors comprises the components of Fe, Cu, B, Mg, Si, Zr, Ni, Ag, Cr, Mn, Ti, V, Zn, RE, and the balance is AL; a rare earth refractory layer material comprises the components of fluororubber,aluminium hydroxide, rare earth oxide, glycerin, silicon carbide, lanthanum phosphate, gadolinium zirconate, and the balance is epoxy resin; and a rare earth water-blocking layer material comprises the components of epoxy resin, tung oil, rare earth oxide, magnesium oxide, zinc oxide, and the balance is nitrile butadiene rubber. The rare earth power cable has good electrical conductivity and mechanical strength, and has high temperature resistance and water blocking performance.
Description
technical field [0001] The invention relates to a power cable for transmitting electric energy, in particular to an aluminum alloy power cable with high water resistance, moisture resistance and high temperature resistance. Background technique [0002] Power cable is a cable product used to transmit and distribute high-power electric energy in the main line of the power system. It is often used in urban power grids, power station lead lines, internal power supply of industrial and mining enterprises, and underwater transmission lines. The proportion of cables in power lines is increasing. Gradually increases and determines the transmission performance of the transmission line. The basic structure of a power cable mainly includes a conductor core, an insulating layer, a shielding layer and a protective layer. The conductor core is the conductive part of the power cable, which is used to transmit electric energy and is the main part of the power cable. [0003] At present, m...
