Product Introduction

621-9938RC is a high-performance industrial automation communication module that uses high-speed CMOS devices, supports MODBUS protocol, and supports
hardware flow control. It is an ideal choice in the field of industrial automation.

ABB press-fit and mechanical connectors embody multi-dimensional process standardization and reliability assurance

In order to meet the basic requirements for connecting electromagnetic wires, ABB provides insulation-piercing Dragon Tooth® crimp-type terminals, which require no welding, no
need to remove the insulation layer, and no special operating skills. Just use the terminals and supporting tools to install them.
Installs in seconds – these tips are made of copper alloy, tin plated and have many tines on the interior surface, the sharp, hard tines penetrate the insulation when the tip is crimped
to the insulated magnet wire and oxide and bite into the wire, creating a reliable, low-resistance connection through intense pressure at the tips and edges of the tines and sliding between the tines and the wire.

“In ABB”s view, the reliability of products also needs to be reflected in the integrated system, because the connector and the cable become a system after they are crimped. The
connection point should not become the weak point on the cable, but should be the weak point in the entire system. The reliability of the connection.” Dong Gang further explained:
“Even if cables of varying quality are used, after crimping with ABB products and tools, the mechanical strength of the connection point should be at least no worse than the cable
itself, and the conductivity should be better than Cables are better, and the temperature rise should not be greater than any point on the cable.”

Link global resources and deepen local innovation and product portfolio advantages

China is still recognized in the world as one of the markets with fast growth, many opportunities, and complex diversity. As one of the important business units of ABB Electric
, installation products not only need to introduce high-quality products into the Chinese market, but also make Chinese customers aware of Installation accessories are important to
the entire electrical system and industrial chain.
Dong Gang said that ABB”s installation products, as a new entrant in the Chinese market, are rooted in localized innovation and are also ABB”s consistent product development
strategies. Through these years of efforts, ABB has launched similar anti-seismic brackets, lightning protection grounding system materials, etc. for the Chinese market. The very ”
down-to-earth” products have been recognized by customers.

The rapid economic development has promoted the continuous acceleration of China”s urbanization process, and the height and scale of modern building groups are
constantly setting new records. These magnificent buildings have put forward higher requirements for the seismic performance of engineering non-structural components. ABB is
based on load mechanics and seismic action calculation as the core. Through ABB Superstrut® bracket products equipped with efficient connectors, as well as tailor-made, stable and
economical disaster protection solutions, ABB provides mechanical and electrical facilities such as pipes, air ducts, and cable trays. A safe and convenient
earthquake-resistant “fortress” can maintain its original working condition no matter how it shakes when the building does not collapse. This is also a mandatory requirement in the
new national standards.

ABB Superstrut bracket products are widely used to build safe and convenient earthquake-resistant “fortresses”
ABB Superstrut bracket products are widely used to build safe and convenient earthquake-resistant “fortresses”

Since third-party test reports are an important basis for measuring the performance of bracket products, ABB bracket products focus on the on-site reducibility of parameter
performance in the test report. Therefore, in the design and manufacturing process, we insist on using high-quality steel from large steel mills and eliminate negative tolerance
materials. The use ensures that the laboratory performance can be restored to the construction site. It is worth mentioning that ABB”s quick-lock products can greatly increase the
installation speed when assembling anti-seismic brackets, reduce installation difficulty and construction intensity, significantly save
installation time and significantly reduce installation costs compared with traditional solutions.

There are more than 8 million lightning strikes every day in the world. The lack of or improper protection of electrical protective equipment will cause casualties and
significant economic losses. ABB complies with the IEC62305 standard and launched the Furse copper-plated round steel solution specifically for the Chinese
market, providing safety for Chinese customers. Reliable, cost-effective lightning protection solution. Furse lightning protection solution can achieve long service life,
lower annual use cost, less maintenance workload and
more convenient construction methods, thereby reducing the risk of personal injury and death loss to less than 10^-5, and the risk of public service loss to less than
10^-3, the risk of cultural genetic loss is less than 10^-4, and it is one of the safer and more reliable lightning protection systems in the world.

In fact, every time a circuit breaker or switch cabinet is sold, there will be sales opportunities for installation accessories or connectors
. Installation products even have a larger market share and capacity than electrical products. Dong Gang predicted that in the future, installation
products will have huge growth potential in both the global and Chinese markets. In particular, ABB Electric has deployed a very stable and efficient
distribution network in China. Installation products can not only enjoy the dividends brought by the sales network, but also enjoy the benefits of the sales network. ABB will
continue to rely on its more than 100 years of global R&D experience and resources in installation products to empower local innovation and provide a more complete
product portfolio and services for the Chinese market.
