Abstract
The invention discloses an ultraviolet-proof insulated cable which comprises main wire cores, control wire cores, a wrapping tape layer, an inner shielding layer, an insulation layer, an outer shielding layer, an ultraviolet-proof layer, a protective sheath and a drainage wire. The number of the main wire cores and the number of the control wire cores are both three. An insulation reinforcing plate is arranged in the middle of the inside of the wrapping tape layer. The insulation reinforcing plate divides the main wire cores and the control wire cores on the two sides of the inside of the wrapping tape layer equally. The wrapping tape layer wraps a grounding wire core and the drainage wire inside. The ultraviolet-proof insulated cable is good in electrical conductivity, long in service life, capable of achieving low smoke zero halogen, environmentally friendly, firm in cable core, resistant to dragging, widely applicable to the fields of computers, communication, power generation, metallurgy, petroleum, chemical industry and the like, and high in shielding property. Meanwhile, the shielding rate to ultraviolet rays reaches 98.6%.
Description
technical field [0001] The invention belongs to the field of cables, in particular to an ultraviolet-proof insulated cable. Background technique [0002] At present, with the rapid development of my country's economy and the increasing level of science and technology, the amount of cables is increasing, and higher requirements are placed on the quality of cables. For example, in the environment of long-term sunlight exposure, strong external extrusion and strong environmental electromagnetic interference, higher requirements are put forward for the cable's anti-ultraviolet performance, core firmness, electrical conductivity and shielding performance. [0003] However, the current general cables have a series of problems such as low shielding performance, weak resistance to dragging, insufficient core strength, and low UV resistance. Only by meeting the requirements can the production and use of cables be better guaranteed. Contents of the invention [0004] In order ...
