High-insulation cable with high flexibility and easy to bend and fabrication method thereof

Abstract

The invention is applicable for the technical field of a cable, and discloses a high-insulation cable with high flexibility and easy to bend. The high-insulation cable with high flexibility and easy to bend comprises a conductor, a high-insulation layer and a sheath, wherein the sheath comprises a low smoke zero halogen flame-retardant inner layer and a low smoke zero halogen flame-retardant outer layer, second protruding thorns are densely arranged on an external circumferential surface of the low smoke zero halogen flame-retardant inner layer and are internally embedded onto an internal circumferential surface of the low smoke zero halogen flame-retardant outer layer, the conductor is formed by twisting a single conductor line or a plurality of conductor lines and is coated in the high-insulation layer, and first protruding thorns are densely arranged on an external circumferential surface of the high-insulation layer and are internally embedded onto an internal circumferential surface of the low smoke zero halogen flame-retardant inner layer coated at the periphery of the high-insulation layer. The high-insulation cable with high flexibility and easy to bend is reasonable in structure, adjacent layers are highly engaged, the high-insulation cable with high flexibility and easy to bend still has relatively high bending and flexible performance in a low-temperature environment, is long in service life, and has a high insulation effect, and the risk of electric leakage is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of wires and cables, in particular to a high-insulation wire and cable with strong stretchability and easy bending and a preparation method thereof. 【Background technique】 [0002] There are many types of wires and cables, and the scope of application is very wide. It involves industries such as electric power, construction, communication, and manufacturing, and is closely related to the national economy. Wires and cables are also known as the "arteries" and "nerves" of the national economy. They are indispensable basic equipment for transmitting electric energy, transmitting information, manufacturing various motors, instruments, and meters, and realizing electromagnetic energy conversion. necessary basic products in society. Therefore, the quality of wire and cable plays a vital role in the national economic system. [0003] At present, inorganic flame retardants such as magnesium hydroxide and aluminu...
