Sewer Camera replacement cable also called pipeline robot cable, pipe inspection cable and sewer inspection cable, etc. which provide towing, lighting, control, TV camera, signal transmission, and power supply for sewer camera and pipeline crawling robot.
Design requirements:
● Flexibility: The cable retracts, unwinds, and drags forward with the action commands of the pipeline crawling robot. Therefore, the cable design of the pipeline CCTV inspection robot requires excellent soft performance to avoid the occurrence of broken cores.
● Wear resistance: The cable is dragged forward with the crawling robot and directly touches the ground and the inner wall of the pipe, so it needs to have excellent wear
resistance to prevent the cable from being worn.
● Tensile strength: The influence of external forces such as cable retracting, cable releasing, and dragging, as well as water scouring force, etc. should also be considered in the design of cables. Therefore, tensile strength is also the basic design requirement of this kind of cable.
● Environmental adaptability: It is used in different pipeline environments, such as urban drainage pipelines, chemical plant drainage pipelines, oil pipelines, etc., and has high requirements of waterproof, oil resistance, acid and alkali salt spray corrosion resistance. So and good environmental adaptability is also an important design requirement for pipeline robot cables.
