<p>An electrical line has electrical strand including metal conductor (1), flame-resistant temperature-resistant insulating layer (2) and casing (3) of polyamide-containing polymer mixture. The insulating layer contains flame-retardant temperature-resistant halogen-free polymer mixture containing 95-80 phr polyolefin, 5-20 phr polymer adhesion promoter, 40-200 phr filler chosen from calcium carbonate, aluminum hydroxide and magnesium hydroxide, 0-15 phr silicon, 0-15 phr oxide or stearate of bivalent metal ion, and 0.1-20 phr stabilizer and processing aid. An electrical line has electrical strand including metal conductor, flame-resistant temperature-resistant insulating layer which surrounds the conductor, and casing of polyamide containing polymer mixture provided on insulating layer. The insulating layer contains flame-retardant temperature-resistant halogen-free polymer mixture containing 95-80 phr polyolefin, 5-20 phr polymer adhesion promoter, 40-200 phr filler chosen from calcium carbonate, aluminum hydroxide and magnesium hydroxide, 0-15 phr silicon, 0-15 phr oxide or stearate of bivalent metal ion chosen from calcium, magnesium, strontium, barium and zinc, and 0.1-20 phr stabilizer and processing aid. The electrical line has temperature resistance of 90[deg] C or more. An independent claim is included for usage of electrical line as an installation line for buildings.</p> |
