Flame-retardant aluminum conductor cable

Abstract

The invention discloses a flame-retardant aluminum conductor cable. The flame-retardant aluminum conductor cable comprises conductors and insulating wire cores, and is characterized in that a PE insulating layer is wrapped on each conductor in an extruding mode to form one insulating wire core; a low-smoke zero-halogen glass fiber belt is wrapped on every two corresponding insulating wire cores in a lapping mode after the two insulating wire cores are combined together, and PE belts are wrapped on the low-smoke zero-halogen glass fiber belts in a lapping mode to form main wire cores; the three wire cores are combined with three insulating wire cores II to form a cable core; a low-smoke zero-halogen glass fiber belt II is wrapped on the cable core in a lapping mode, a PE belt II is wrapped on the low-smoke zero-halogen glass fiber belt II in a lapping mode, an armor layer formed by winding two layers of aluminum tapes is wrapped on the PE belt II in a lapping mode, a double-layer mica tape fireproof layer is wrapped on the armor layer in a lapping mode, and an outer sheath made of PE insulating materials is arranged outside the fireproof layer; each insulating wire core II is formed by wrapping a PE insulating layer on an aluminum conductor in a lapping mode; a middle wire core is arranged in the center of the cable. The flame-retardant aluminum conductor cable is simple in structure and has good flame retardance, high temperature and low temperature resistance, acid-base resistance, oily water resistance, tearing resistance, flexibility and environment friendliness.

Description

technical field [0001] The invention relates to a flame-retardant aluminum conductor cable, which belongs to the field of electric wires and cables. Background technique [0002] In recent years, especially since 2005, the price of copper metal in the international market has risen greatly. Since 2005, copper has risen from $2,000 / ton to $9,000 / ton. The economic crisis in 2008 has caused copper prices to fall back to However, in 2009, the copper price rose from US$3,000 / ton to US$8,000 / ton. By the end of December 2011, the international copper price hit a record high again, and the copper price per ton exceeded US$9,500. As the pressure of national inflation has increased sharply this year, copper prices still have a strong upward trend, and copper materials account for more than 70% of the cost of copper cables, so that the price of copper cables is also rising, which leads to users Input costs have increased significantly. Faced with rising copper prices and unforeseen p...
