Recently, the 14th China International Modern Railways Exhibition kicked off at the Shanghai Exhibition Center, marking the launch of "Asia's first railway exhibition." This event has become a key platform for showcasing cutting-edge technologies and innovations in the railway sector. Among the exhibitors was Levin M Electronics, a leading provider of high-quality power measurement solutions in the electricity sensor market. The company presented a range of advanced products tailored for the railway industry, drawing significant attention from visitors and potential clients.
Lyme Electronics, along with several other key players in the railway industry, made their debut at MODERNRAILWAYS2017. This exhibition has been held annually since 1992 and has grown into one of the most influential events in the railway sector across Asia. For over three decades, it has served as a crucial platform for technology exchange and business development.
Lyme China has long been a prominent player in the railway market. Since entering the Chinese market in the 1980s, the company has established itself as a trusted supplier of specialized products designed to meet the unique demands of rail environments. Their solutions have been widely adopted by major global manufacturers such as Siemens, Bombardier, Alstom, CSR, and CNR.
As China’s railway technology continues to advance, the integration of modern information and artificial intelligence technologies is becoming increasingly important. Power sensors and precise power measurement systems are playing a vital role in ensuring the safety, efficiency, and sustainability of railway operations. Lyme Electronics aims to support the future development of China’s railways by offering safer, more efficient, and environmentally friendly solutions.
At this year’s exhibition, Lyme Electronics showcased several innovative products developed through recent R&D efforts:
DVL Series Products
The DVL series is designed for small to medium voltage measurements in industrial and railway applications. It meets strict railway standards such as EN50155:2007 and EN50121-3-2:2006. With its innovative digital insulation technology, the DVL series offers energy savings of up to 30%, reduced weight by 30%, and superior immunity to electromagnetic interference. It is fully compatible with previous generations of sensors.
DVM Series Products
The DVM series is ideal for small to medium voltage measurements in both industrial and railway settings. It complies with international railway standards and weighs 54% less than traditional voltage sensors. Its exceptional resistance to electromagnetic interference makes it a reliable choice for critical applications.
LTC Series Products
The LTC series is a modular current sensor suitable for traction locomotives. It adheres to the railway standard EN50155 and features a compact, flexible design that allows for both lateral and longitudinal mounting. It provides electrical isolation and can measure DC, AC, and pulse currents with high accuracy.
LFxx10 Series Products
The LFxx10 series represents a breakthrough in performance, offering capabilities comparable to fluxgates while providing better cost efficiency and system performance. It eliminates issues like fluxgate noise and primary current starting delay, making it an excellent choice for high-performance applications.
GO Series Products
Lyme’s latest GO series features an integrated primary conductor in SO8 and SO16 packages. This small, isolated current sensor provides complete isolation and is resistant to external magnetic fields thanks to its unique gradient measurement design.
ART Series Rogowski Coil & ATO Series Open Current Transformer
The ART series is designed with IP67 protection and a flexible open structure, using high-precision Rogowski coil technology to measure AC current effectively. The ATO series is a low-phase-shift open current transformer known for its high precision. Both series meet CE certification and IEC61869 standards, ensuring reliability and compliance.
Power sensors play a critical role in the railway sector, with demand driven by three main areas: providing control and protection signals for locomotive traction systems, supporting railside equipment, and enabling energy management and maintenance. Lyme Electronics offers tailored solutions for each of these areas, with most rail vehicles currently using their power sensors.
In the future, Lyme Electronics plans to continue investing in R&D, focusing on improving sensor performance and reliability. As a leader in the global rail transit market, the company has maintained long-term partnerships with major railway manufacturers. With a 5-year quality assurance commitment, Lyme continues to build trust and deliver cost-effective, high-quality products to the market.
AD8 standard floating Solar Cable is a kind of equipment used for floating photovoltaic power generation. It consists of photovoltaic cells that convert solar energy into electricity. The device is designed to float on the water, while it can be fixed to the water by a buoy and anchorage device to prevent drifting.
AD8 standard floating solar cable has the following characteristics:
1. Efficient use of solar energy: photovoltaic cells can convert solar energy into electricity to achieve efficient power generation.
2. Environmentally friendly: photovoltaic power generation does not produce pollutants and greenhouse gases and is environmentally friendly.
3. Save land resources: Floating solar cable can use the space on the water surface, saving the use of land resources.
4. Strong wind and wave resistance: floating solar cable adopts stable design, has strong wind and wave resistance, and can operate normally in bad weather conditions.
5. Easy installation and maintenance: Floating optical cables are relatively simple to install and maintain, and can be quickly deployed and adjusted.
AD8 standard floating solar cable is suitable for a variety of water environment, such as lakes, reservoirs, rivers, etc. It can be used in power stations, farmland irrigation, drinking water treatment and other fields to provide local clean energy and power supply.
