Abstract

The invention discloses a low-smoke halogen-free flame-retardant cable, and the cable comprises a cable core, a filling layer wrapping the cable core, a wrapping layer wrapping the filling layer, an inner sheath wrapping the wrapping layer in an extruding manner, an aluminum sheath wrapping the inner sheath in an extruding manner, and an outer sheath wrapping the aluminum sheath in an extruding manner The cable core consists of a conductor, a wrapping shielding layer wrapping the conductor, an insulating layer wrapping the wrapping shielding layer, and a shielding layer wrapping the insulating layer. The cable provided by the invention employs a special structure design, especially employs a novel rubber material, is low in smoke, is halogen-free, is excellent in resistance to oil and aging and mechanical performances, is good in resistance to ozone, flame and low temperature and insulation performances, is excellent in shielding effect, is good in integrated performance, and is suitable for the fields of petroleum, chemical and oceanographic engineering and rail traffic.

Description

technical field [0001] The invention relates to a cable, in particular to a low-smoke halogen-free flame-retardant cable. Background technique [0002] The wire and cable industry is the second largest industry in China after the automobile industry, and the product variety satisfaction rate and domestic market share both exceed 90%. Worldwide, China's wire and cable output has surpassed that of the United States, becoming the world's largest producer of wire and cable. With the rapid development of China's wire and cable industry, the number of new enterprises has been increasing, and the overall technical level of the industry has been greatly improved. The continuous and rapid growth of China's economy has provided a huge market space for cable products. The strong temptation of the Chinese market has made the world focus on the Chinese market. In just a few decades of reform and opening up, China's cable manufacturing industry The huge production capacity formed has im...
