Abstract

The invention discloses an isolation type composite cable and relates to the technical field of cables. The cable comprises a reinforcing core and three cable core wires, and a loose sleeve layer, aninner shielding layer, a water isolating layer, a copper strip shielding layer, an isolation layer, a polyvinyl chloride outer sheath layer and an outer wear-resistant layer are sequentially wrapped outside the reinforcing core and the three cable core wires, and gaps in the loose sleeve layer are filled with water-blocking paste, the thickness of the upper end of the outer wear-resistant layer is smaller than the thickness of the lower end, the isolation layer is made of inorganic mineral insulating layers. The device has the advantages of simple structure, multiple shielding, good shieldingeffect, and moisture prevention.

Description

technical field [0001] The invention relates to the field of cables, and more specifically relates to an isolated composite cable. Background technique [0002] Cables are indispensable basic equipment for energy transmission and information transmission. Today, with the rapid development of social informatization and electrification, wires and cables have become one of the most important basic products in economic construction. The wire and cable industry is also a supporting industry. The products must meet the requirements of the main industries of the national economy for the performance of wire and cable. The national economy believes that most industries are related to wire and cable, and its industrial status is very important. The communication cable for data transmission attaches great importance to the quality of communication, and the electromagnetic interference from the outside can easily cause data errors. The shielding layer of ordinary cables is mostly made o...
