High-flame-retardant and high-temperature-resistant cable and processing method thereof

Abstract

The invention relates to cable processing, in particular to a high-flame-retardant and high-temperature-resistant cable and a processing method thereof.The processing method of the high-flame-retardant and high-temperature-resistant cable comprises the following steps: 1, a cable core penetrates through two injection molding mechanisms in a high-flame-retardant and high-temperature-resistant cable processing device; 2, the two injection molding mechanisms respectively perform injection molding on different injection molding objects on the cable core; and 3, the two injection molding mechanisms carry out segmented injection molding on the cable core to form the high-flame-retardant and high-temperature-resistant cable. The high-flame-retardant and high-temperature-resistant cable comprises the cable core, coating rubber I and coating rubber II, the coating rubber I and the coating rubber II coat the cable core, and raw materials of the coating rubber I and the coating rubber II are different. One section of the coating rubber I and one section of the coating rubber II are flame-retardant rubber, so that separation is formed on the cable, and the cable has the flame-retardant characteristic.
