A reinforced waterproof floating cable

Abstract

The invention discloses a reinforced waterproof floating cable, which comprises a cable core located at the center of the cable, a foam inner liner is filled outside the cable core, and a braided reinforcement layer and a waterproof outer sheath are sequentially arranged outside the foam inner liner. The invention adopts a waterproof outer sheath and a braided reinforcing layer to form double-layer protection, which can prevent water from penetrating into the cable, enhance its waterproof function, improve the tensile performance of the cable, prolong the service life of the cable, and improve economic benefits. And the position of the original foam layer is moved from the outer sheath to the inner lining layer, which will not affect the ability of the cable to float on the water surface, but also enhance the waterproof function of the cable.

Description

[0001] technical field [0002] The invention relates to a high-end cable, in particular to a reinforced waterproof floating swimming pool cleaning cable. Background technique [0003] The structure of the existing floating cables is usually composed of the conductor of the insulating sheath, the inner sheath and the foamed outer sheath, that is, the inner sheath is extruded outside the conductor insulation layer, and the material of the inner sheath is thermoplastic elastomer; the inner sheath The outer layer is extruded to cover the outer sheath, and the material of the outer sheath is a mixture of thermoplastic elastomer, foaming agent and lubricating oil. The three are mixed according to a certain weight ratio and then extruded outside the inner sheath. The agent is directly mixed into the outer sheath material, and it is preheated and expanded during the extrusion process, so that foaming micropores are formed in the outer sheath to form a foam layer, so that the overal...

AI Technical Summary

Problems solved by technology

Although the cable can float on the water surface and work normally, but considering the frequent work of the cable on the water for a long time, coupled with some artificial pulling effects and bad use, once the cable is damaged, the waterproof performance of the cable will be greatly reduced. The service life of the cable cannot guarantee the long-term normal use of the cable
