High-flexibility tensile flame-retardant fireproof shielding towline cable

Abstract

The invention discloses a high-flexibility tensile flame-retardant fireproof shielding towline cable comprising a tensile element which is arranged at the center of the cable. The tensile element is externally provided with a first cable core layer and a second cable core layer in turn. The second cable core layer is externally wrapped by a first smooth polyester film isolation layer. The smooth polyester film isolation layer is externally extruded by a fireproof lining layer. The fireproof lining layer is externally provided with a copper foil wire braided shielding reinforced layer. The copper foil wire braided shielding reinforced layer is externally wrapped by a second smooth polyester film isolation layer. The second smooth polyester film isolation layer is externally extruded by a composite TPU elastomer sheath layer. The gap between the tensile element, the first cable core layer and the second cable core layer is filled with fibers. The high-flexibility tensile flame-retardantfireproof shielding towline cable has the characteristics of being high-flexibility, tensile, fireproof, long in service life and high in reliability so that the use requirements of the modern intelligent industrial electronic system can be met.

Description

technical field [0001] The invention relates to a highly flexible, tensile, flame-retardant and fireproof shielded towline cable, which is mainly used in industrial electronic systems, automatic production lines, storage equipment, robots, fire protection systems, cranes, numerical control machine tools and metallurgical industries.

With the in-depth development of industrial automation and intelligence, the actions that industrial devices need to complete in their work are becoming more and more complex, faster and faster, and more accurate. Therefore, it is required that the supporting drag chain cables must be improved. , to meet the needs of intelligent industrial devices. [0003] The conventional drag chain cables currently used in indust...

AI Technical Summary

Problems solved by technology

[0004] 1. The moving speed cannot meet the requirements of the equipment, and the failure rate of fast moving is high;

[0005] 2. The tensile strength of the cable is low, which cannot meet the requirements of high-load mechanical bending, and the cable is prone to failures such as disconnection;

[0006] 3. The overall flexibility of the cable is not enough to meet the requirements of excessive bending and multi-dimensional bending;

[0007] 4. Due to the increasingly complex application environment of cables and dense equipment, cables are required to have fire safety performance, which conventional cables do not have.

[0008] 5. The overall reliability of the cable is low and the service life is short, which cannot meet the long-term safe and reliable operation of industrial devices
