Steel cross arms of different configurations are used on overhead lines, transmission towers, transmission lines, wood poles, utility poles, power poles, and light poles.
To make the steel cross arm more stable, there will be two cross arm braces to support the main cross arm by delta connection.
Chinese PLC market is expected to usher in the new blue ocean, national brands will gradually wake up
Programmable Logic Controllers (PLCs), often referred to as industrial computers, play a crucial role in the advancement of industrial automation. These devices are designed for reliable and safe operation, making them indispensable in various sectors such as metallurgy, power generation, and transportation. As technology evolves, PLCs continue to adapt, with large-scale models leading the way in performance and functionality.
Medium-sized PLCs are gradually bridging the gap between their smaller and larger counterparts, expanding into more complex applications. Meanwhile, small-sized PLCs, though compact, offer excellent performance and are expected to see significant growth in the coming years. Their affordability and efficiency make them ideal for a wide range of tasks, from simple control systems to more advanced automation setups.
In China, the PLC market is highly competitive, with both domestic and international brands vying for dominance. Despite challenges like the market downturn in 2015, which saw a drop of over $8 billion in sales, the industry began to recover by 2017. It is projected that global revenue will grow at a compound annual rate of 3.6% or higher through 2020. The Asia-Pacific and U.S. markets are expected to lead this recovery, while the Chinese market slowly emerges from its slump, entering a new phase of competition.
Currently, foreign brands still hold a strong position in the Chinese market, with European and American companies like Siemens, Schneider, and Rockwell maintaining high market shares. Domestic brands, although improving, are still in the early stages of development and lack the comprehensive strength of their international counterparts. For instance, Siemens has a dominant presence in China, with many local companies acting as its agents. Its PLCs are widely used across industries such as metallurgy, chemical processing, and printing.
However, some domestic brands like Delta, Helishi, and Ancon are gaining ground, showing promising growth and forming a more competitive landscape. As the Internet of Things (IoT) era approaches, PLCs are set to play an even more vital role. While traditionally known for their industrial control capabilities, PLCs also have great potential in networking and smart integration.
The rise of IoT has driven innovation in manufacturing, emphasizing the need for interconnected systems. PLCs, with their ability to collect data and perform logical operations, are key components in achieving intelligent control. As more devices become connected, PLCs will be essential in creating seamless communication between machines and systems.
To fully realize this potential, PLCs must enhance their communication capabilities. This includes supporting multiple fieldbuses, standard protocols, and integrating with factory management networks. Compliance with international standards like ISO/IEEE will also be critical for broader adoption.
Looking ahead, the application of PLCs is expected to expand beyond traditional areas like machine tools and packaging machinery. While the machine tool industry may see slower growth, the robotics sector is likely to provide new opportunities. As industries become smarter, the demand for efficient and flexible control systems will continue to rise.
Major companies are investing heavily in PLC development, aiming to meet the growing need for digitalization and automation. Large-scale PLCs are becoming more advanced, offering enhanced networking features and compatibility with industrial computers and Ethernet. At the same time, small PLCs are moving toward simpler, cost-effective designs, making them more accessible to a wider range of users.
As the market evolves, the focus on affordability, reliability, and flexibility will shape the future of PLCs. With continuous innovation and increasing investment, the PLC industry is poised for a bright and dynamic future.
The function of the steel cross arm is to support distribution transformers, fuses, isolating links, and other line equipment.
