Embodiment Construction

[0009] The structure of the present invention is as figure 1 As shown, the conductor structure adopts the fifth soft copper conductor 1 stipulated in the national standard GB / T3956-2008 "Cable Conductor", and the soft copper conductor 1 is wrapped with isolation tape 2; Layer 3. The insulating material of the insulating layer 3 is IE4 type insulating material; the gap between the cable cores is made of water-blocking filling layer 4, and the water-blocking filling is made of intumescent water-blocking material; the water-blocking reinforcement layer 5 and the waterproof outer sheath 6 are made of SE3 rubber Material extrusion package. The waterproof outer sheath, water-blocking reinforcing layer and water-blocking filling improve the waterproof performance of the cable, and the structure also plays the role of anti-biting, corrosion resistance, and wear resistance.

[0010] The invention replaces the single sheath structure of the traditional cable, that is, after the rubber...

Abstract

The invention discloses a special waterproof rubber-sheathed flexible cable for waterscape fountains, which includes a cable core formed by twisting several wire cores, and a water-blocking filling layer is filled between each wire core and outside the cable core, and outside the cable core in turn Extruded waterproof reinforcement and waterproof outer sheath. The wire core is composed of an annealed copper conductor in the middle, an isolation strip wrapped around the annealed copper conductor and an insulating layer extruded outside the isolation strip. The invention is mainly suitable for transmitting electric energy under 750V underwater, has good waterproof performance and bending performance, is suitable for use in complex underwater environments, can resist acid and alkali corrosion, prevents biting, and has strong tensile strength. Withstand mechanical impact.

Description

[0001] technical field [0002] The invention relates to a cable, in particular to a special waterproof rubber-sheathed flexible cable for waterscape fountains. Background technique [0003] The existing special cables for waterscape fountains generally use ordinary JHS type waterproof cables, which have waterproof function and are suitable for underwater power transmission. Its structure is: a layer of insulation is extruded outside the conductor to form a core, several cores are wound to form a cable core, the cable core is wrapped with a water-blocking tape, and then an outer sheath is extruded. Although this type of JHS waterproof cable has a waterproof function, considering that the cable is immersed in water for a long time under high water pressure, and often encounters uncertain environmental factors such as animal bites, acid and alkali corrosion, and mechanical collisions, it will affect normal operation. Use, so that the cable can not maintain good electrical in...
