The X-Ray 8700 NXT installed at the end of the CV line for final quality control

ZTT uses the X-Ray 8700 NXT for the final quality control in its submarine cable production line

Final quality assurance of submarine cables

the submarine cables, ensuring that only faultless cables are delivered. The X-Ray 8700 NXT can be used for cables with solid, stranded or Milliken conductors with single-, double- or triple-layer insulation. It is also suitable for quality control of insulation material based on polypropylene. By combining the X-Ray 8000 Advanced/ NXT at the beginning and the X-Ray 8700 NXT at the end of the line, the shrinkage values for all three insulation layers of the cable can be determined, ensuring an optimum process control.

Worldwide, more than 1,500 devices of the X-Ray 8000 series are in use. The systems precisely measure the concentricity, wall thickness, diameter and ovality of medium, high and extra-high voltage cables with up to three different layers. The X-Ray 8000 Advanced or NXT models are installed at the hot position and immediately provide information for fast centring of the crosshead and automatic control of the parameters. In order to provide customers with the highest possible quality of submarine cable, ZTT also uses the X-Ray 8700 NXT at the end of the CV line for a final quality assurance. The system precisely measures the wall thickness, diameter and eccentricity of

The immediate and loss-free transmission of data is a feature of the increasingly digital and globally networked world. In order to be able to transmit large amounts of data quickly across borders and even continents, high-quality submarine cables are required. Chinese manufacturer ZTT uses Sikora’s measuring and control devices of the X-Ray 8000 product range for quality control in its CV line. During production, manufacturers of submarine cables face the challenge of producing cables for long distances with as few joints as possible, as these increase the risk of potential breakdown. To ensure the quality and durability of the cables, manufacturers can use X-ray technology from Sikora for quality control in CV lines.
