[0002] Water recreation facilities include water parks, water theme parks, water resorts or other water recreation venues. Water recreation facilities are designed to provide tourists with various water entertainment activities and experiences. Cables for water recreation facilities mainly provide power, signal transmission, video transmission, etc. for water recreation equipment. Power supply includes power supply for equipment such as water pumps, lighting and sound systems. Cables are used to connect equipment and power supply to ensure the normal operation of facilities. Signal transmission includes remote equipment parameter adjustment and data monitoring, etc. Video transmission includes camera monitoring and video transmission.

[0003] At present, the cables used in water amusement facilities are mainly laid through underwater pipes. The power lines, signal lines and video lines are laid separately. Under the protection of the pipes, the cables are not easily damaged by external forces. They are reliable, waterproof, moisture-proof and aging-resistant. However, the separately laid cables are expensive, difficult to lay, and cumbersome to maintain during use. Whether it is the use cost, installation cost or maintenance cost, they are relatively high.

[0021] Specifically, the formation process of the composite cable for water amusement facilities is as follows: first, electrical copper rods are drawn and twisted to form a cable conductor 1, and then cross-linked ethylene propylene rubber is extruded on the outside of the cable conductor 1 to form an insulation layer 2, thereby forming a conductive core.

Then, foamed polyethylene is extruded on the outside of the water-blocking tape layer 6 to form a suspension layer 7. Finally, high-density polyethylene is extruded on the outside of the suspension layer 7 to form an outer sheath 8, thereby forming a composite cable for water amusement facilities.

[0022] Furthermore, the utility model adopts a three-wire composite structure, integrating three cables for power transmission, signal transmission and video transmission into one, which not only simplifies the production, transportation, installation and maintenance costs, but also the composite cable has a suspension layer 7, which is extruded from polyethylene foam material.
