Imported High-speed Railway Cable Testing Equipment Made in China

Imports of high-speed rail and cable testing equipment domestically developed <br> <br> facing our country is long, high-speed rail to run grim security situation, in order not to let the Chinese high-speed rail power outage occurs frequently, in order to let the Chinese high-speed rail from thunder and lightning and other inclement weather . Shenzhen Longren Reverse Research Division is specialized in double-sided, multi-layer circuit board copy board (clone board), change board, BOM list production, reverse push schematic, PCB mass production, chip decryption, prototype production, SMT processing, etc. Work, professional high-tech enterprise that provides complete solutions for electronic products for domestic and foreign customers. In order to narrow the gap between domestic products and foreign high-end technologies, we have long used the reverse research methods of PCB copy board to develop imported equipment locally. In view of the current status of high-speed railway cable testing equipment, Longren has introduced the German series of advanced high-speed cable testing equipment, such as cable outer sheath fault tester, wire and cable high resistance fault locator, cable dielectric loss tester, and other equipment for PCB copy board And the Second Development and Innovative Research The Chinese people will never forget the “6.30” Beijing-Shanghai high-speed rail was launched in the world. But it also failed to forget the “7.23” Wenzhou train car accident. This successive incident has not only shown Beijing. The weak issues of the Shanghai High Speed ​​Rail in the contact network and the power supply system also exposed the deficiency of China's high-speed rail power supply testing equipment technology. The ridicule of other countries is still in the ears. Researchers in our country should strengthen the protection measures for high-speed rail power supply cables. Not only do they have to learn advanced techniques from high-end PCB copy boards in foreign countries, but also have to put forward a series of high-tech technologies that have been verified by domestic practice. Measures and constructive improvement programs.

The failure of China's high-speed rail power supply cable <br> <br> analysis of 27.5kV and 10kV AC power cable is the introduction of high-speed rail part of the European and Japanese high-speed rail technology. In the digestion and absorption of this technology, some high-speed PCB PCB copying board design and construction have taken a lot of detours in combination, leading to single-core high-speed rail power supply cable running technology does not meet the requirements, but also failed to catch up with international standards. According to investigations, 44 out of the sudden power outage accidents in a high-speed railway in China have been caused by the breakdown of the intermediate joints since 2010, and the insulation resistance of the outer sheath of the single-core cable has not reached the national standard and has caused extensive damage. Point detection difficulties and water branches are also important causes of failure.

PDC Drill Bits

A unique combination of tungsten carbide and diamond cutters makes PDC bits highly wear resistant, providing reliable performance in challenging drilling conditions. Whether used for surface drilling, directional drilling or deep hole drilling, Langsun Carbide's PDC drill bits deliver superior results, reduce downtime and increase productivity.

PDC bits are widely used in industries such as mining, oil and gas exploration and construction, where they must drill through a variety of formations. These bits feature a solid tungsten carbide body with diamond inserts for fast and efficient drilling in tough rock formations. Our PDC bits offer excellent stability, higher penetration and longer life.

From exploration drilling to well completions, our comprehensive line of PDC bits covers a wide range of applications. We offer a variety of designs, sizes and configurations to meet different drilling requirements. Langsun Carbide's team of experienced engineers works closely with you to understand your specific drilling needs and provide tailor-made solutions to optimize efficiency and cost-effectiveness.
