SDS Plus and SDS Max drill bits can be used for drilling operations in concrete, reinforced concrete, granite and similar materials. SDS-Plus has a drilling diameter of 4mm to 32mm and a drilling depth of 110mm to 1000mm; SDS-Max has a drilling diameter of 12mm to 52mm and a drilling depth of up to 1200mm.

SDS Drill Bits are available with two (properly shaped integral straight edges), three (star arrangement) or four (integral cross arrangement) inserts, made of cemented carbide. They are deeply embedded in the steel head with industrial solder and are characterized by a high degree of mechanical and heat resistance.
SDS Plus and SDS Max Bits should not only be selected based on the diameter of the drilled hole, but also their depth standard. Both of these measures are necessary to maximize productivity.
High-speed expansion of the power industry, low-voltage electrical equipment industry opportunities
In recent developments, the construction team from the Jiangsu Yangzhou Power Supply Company has been installing an intelligent regulated capacity distribution transformer within the Jiangsu Distribution Network Construction and Management Demonstration Zone in Yongqiao Village, Gongdao Town, Yangzhou. This initiative marks a significant step forward in modernizing the local power infrastructure.
The first batch of transformers deployed in the Yangzhou Power Grid is capable of automatically adjusting their working capacity between 400 kVA and 125 kVA based on fluctuating load demands. According to estimates, each transformer can save over 9,000 kilowatt-hours of electricity annually through this intelligent adjustment process. This not only improves energy efficiency but also reduces operational costs and environmental impact.
Traditionally, grid-configured transformers are set according to the highest power load in a given area. However, during peak electricity usage times, these transformers often operate at only one-third of their capacity, while spending two-thirds of the time handling lower loads. The larger the transformer's capacity, the higher the energy losses during operation. By using smart transformers that adapt their capacity to match real-time demand, power systems can achieve better energy conservation and reduced emissions.
This year, the global economy is expected to grow by less than 2.4 percentage points, with potential declines in 2014. Under such challenging market conditions, businesses worldwide face intense competition. For companies in the low-voltage electrical appliances sector, the key challenge is how to effectively develop and expand their markets. Despite these difficulties, the development momentum of China’s low-voltage electrical industry remains strong, and companies must remain prepared for future opportunities and challenges.
Low-voltage electrical appliances are widely used across industries, transportation, and residential sectors. With the ongoing transformation of the power and distribution industries, as well as the rapid expansion of the power sector, the low-voltage electrical appliance market is brimming with potential. During the "Twelfth Five-Year Plan" period, the State Grid invested a total of 1.5 trillion yuan in smart grid construction and digitalization, averaging about 300 billion yuan annually. This investment ensures steady growth for the low-voltage electrical appliance industry.
Additionally, the rapid increase in urban populations is driving higher demand for electricity generation and consumption, further boosting market growth. Looking ahead, the low-voltage electrical appliance market is expected to continue expanding.
Currently, China’s low-voltage electrical appliance industry is characterized by small-scale production, high volume, and a large number of companies producing mid-to-low-end products. Over 90% of enterprises are engaged in repetitive manufacturing, with three generations of products coexisting in the market. However, in the coming years, the industry structure is expected to evolve significantly, shifting toward high-performance, high-reliability, compact, digitalized, modular, and standardized products.
The growth of the low-voltage electrical appliance industry is closely tied to the national economic development, the needs of industrial automation, and the advancement of new technologies, processes, and materials. As the national economy continues to grow rapidly, the prospects for the low-voltage electrical appliance industry are promising.
With the continuous changes in the power and distribution sectors, and the accelerated expansion of the power industry, the low-voltage electrical appliance industry is facing numerous opportunities. The State Grid’s substantial investments in smart grids and digital infrastructure will further support the industry’s long-term development. Combined with the increasing demand driven by urbanization, the future outlook for low-voltage electrical appliances remains positive.
