Kansai Tsushin Densen Co., Ltd., based in Takarazuka-shi, Hyogo, Japan, is a specialist in the manufacture of electric wires and cables as well as in providing technical support for communication cables. Since its foundation in 1965, the company has developed a wide range of cables for communication, broadcasting and network applications. These include coaxial cables, twisted pair cables, high-frequency cables, outdoor cables with small diameters, surveillance camera cables or custom-designed cables. In order to monitor its production processes, Kansai Tsushin Densen uses Sikora’s “Capacitance 2000” and “Centerview 8000” measuring devices.

The company uses several Sikora measuring and control systems, such as the “Centerview 8000”, which provides continuous online measurement of the insulation thickness, outer diameter, eccentricity and ovality with the highest level of accuracy. By combining the “Centerview 8000” with the processor system “Ecocontrol 6000”, product parameters can be visualised and monitored in real time.

In addition, Kansai Tsushin Densen uses the accumulated trend data of the “Centerview 8000” for data analysis. Thanks to this technology, the company has been able to significantly shorten the start-up process. “Previously, we used to take samples at the take-up section for structural inspection. If no issues were found, we continued production from that point. However, if any problems were detected, the process had to be repeated, resulting in significant start-up losses. By using Sikora’s “Centerview 8000”, this process was eliminated, leading to a reduction of start-up losses and, as a result, savings on resin and conductor materials,” says Nobukuni Nakayama.

Besides, the company relies on Sikora’s “Capacitance 2000” device together with the “Ecocontrol 6000” for real-time capacitance measurement, as well as SRL (Structural Return Loss) and VSWR (Voltage Standing Wave Ratio) analysis. This combination allows for easy visual confirmation of the product conditions during manufacturing. “We also manufacture insulation for 12 G-compatible products on our production lines. The SRL and VSWR analysis functions help to stabilise impedance characteristics, detect fine periodic fluctuations in insulation or inner conductors, and identify causes such as equipment vibrations,” Nobukuni Nakayama emphasises the importance of SRL analysis during manufacturing. Real-time checks of capacitance, SRL, and VSWR enable immediate judgements of the process stability and reduce start-up losses.

“For our company, the main benefit of using Sikora devices is that we can guarantee our customers stable product quality. For our customers, the ‘Centerview 8000’ provides transparency in quality assurance based on measured data, and the ‘Capacitance 2000’ ensures a reliable cable supply by providing uniform electrical characteristics. As a result, they benefit from high-quality cables with excellent high-frequency performance,” states Nobukuni Nakayama.
