ABB's business in China's electric power sector encountered Waterloo. According to the results recently released by ABB, its investment in China's power industry maintained rapid growth, and its 2010 performance in China's power sector declined by 19%.
In this regard, ABB North Asia and ABB (China) Co., Ltd. President Fang Qin said: "ABB's challenge comes from a number of growing competitors, more and more competitors continue to emerge, the current market prospects in some areas It is not very clear, especially in the transmission industry."
He pointed out that the main part of the power business affecting ABB is the transmission business, and the development of the power distribution business is still good.
According to ABB's performance report, ABB (China) sales in 2010 were US$4.4 billion, a year-on-year increase of 3%. Among them, the automation business grew fastest, reaching 42%, but the power business became a “delayed†business segment, which fell close to 20%.
In particular in the transmission market, domestic competitors are besieged. In recent years, the market share of domestic companies has increased dramatically, and the market share of high-end transmission has exceeded the market share of foreign companies.
Data from XJ Electric shows that at present, in the UHV DC transmission project, the market share of Xuji's converter valve has reached 50%, and the market share of control and protection equipment has reached 75%.
A group of data from the National Grid and GF Securities is just an indication of the decline in ABB's transmission market: In the 500kV transformer market, ABB’s share fell from 26% in 2006 to 14% in 2009, and TBEA From 16% to 36%; the same time period, ABB accounted for 24% of the 200kV transformer market fell to 6%, while TBEA increased from 22% to 24%.
The data released by the State Grid also shows that among the three successful companies that were announced by the State in 2010 for smart grids, except that the circuit breakers were all obtained by Siemens, the rest were almost entirely absorbed by domestic companies. Among them, in the field of transformers, TBEA and China West have obvious advantages, with share of 40% and 33.3% respectively.
People in the industry believe that with the continuous breakthrough of core technologies in the field of power transmission and distribution, domestic transmission and distribution equipment manufacturing technologies have reached internationally advanced levels in some areas. At the same time, the State Grid Corporation of China will consider localization requirements when bidding, which will undoubtedly give Foreign and domestic electric equipment companies, including ABB, pose new challenges.
Faced with the strong siege of leading enterprises in the domestic and international electrical equipment industry, ABB has made strategic adjustments from product development, market development, and service business.
Fang Qin said that ABB will have several new factory construction projects this year, including the mine hoisting system and the Azipod green ship propulsion system factory. At the same time, it will expand more business in China, such as integrating analysis systems, opening up mid-markets, and formulating mid-market strategies.
Liu Xingang, head of ABB's power system department in North Asia and China, said that in the course of recovery of the power market in 2011, with the intensification of market competition, ABB will accelerate the process of localization, realize cost optimization and open up new channels. Increase the development and research and development of mid-market and develop products suitable for mid-market. At the same time, it strengthened its service and launched a comprehensive service business.
On February 23, 2011, Liu Xingang returned to ABB as the person in charge of power systems in North Asia and China. Liu Xingang worked in ABB China's power business for 9 years before returning to ABB to work at Westinghouse Electric.
Strengthening cooperation with the government and the domestic power grid will be a major focus of ABB's 2011 strategy. It is understood that on February 17, 2011, ABB Group cooperated with China Southern Power Grid to design, manufacture, install and debug 800 kV UHV DC for a converter station for Yunnan Uzada-Guangdong UHVDC power transmission project. Transformer equipment.
In fact, at the end of 2010, heads of multinational corporations such as ABB and Siemens paid frequent visits to the China Southern Power Grid and the State Grid, and the smart grid meals invested by trillions of yuan in China’s power grid upgrades.
2.0mm Female Pin Header
2.0mm (0.079") Pitch Female Headers
Overview
2.00 mm pitch female sockets/headers are low-profile connectors designed for signal and low power PC board connections when space is at a premium. Options include through-hole, surface mount and can be customized for mixed technology, press-fit and pass-through terminations. The pins and blades are available in various sizes, counts, amperages, and plating.
The 2.0mm can accommodate a maximum current of 3A, with a 30 to 22 AWG wire size, and up to 40-positions. Antenk offers 2.0mm pitch female headers in either vertical or right-angle orientation at high quality and affordable China-quoted price that snuggly fits with the pins of a male header and acts as a receptacle.
The 2.0mm pitch female headers are commonly found in PC`s and are also made to work in Arduino boards, Arduino Pro and Arduino Mega with either single or double-row female headers, facilitating connections for programming and incorporation into other circuits. They have the perfect height for clearing the USB-B connector and great for stacking multiple shields.
Female header always called as [Header connector", Antenk provide widely range of header connector, from 2.54mm (.100″ inch) pitch to 1.0mm (.039″ inch) pitch. The number of pins (contacts) is from 2 to 40 pins per orw. There are three type: Straight (Dip Vertical), Right angle, SMT (surface mount).

Mount Type: Through-hole vs Surface Mount
At one side of this female header is a series of pins which can either be mounted and soldered directly onto the surface of the PCB (SMT) or placed into drilled holes on the PCB (THM).
Through-Hole (Poke-In)
Best used for high-reliability products that require stronger connections between layers.
Aerospace and military products are most likely to require this type of mounting as these products experience extreme accelerations, collisions, or high temperatures.
Useful in test and prototyping applications that sometimes require manual adjustments and replacements.
2.0mm vertical single row female header, 2.0mm vertical dual row female header, 2.0mm right-angle single row female header and 2.0mm right-angle dual row female header are some examples of Antenk products with through-hole mount type.
Surface-Mount
The most common electronic hardware requirements are SMT.
Essential in PCB design and manufacturing, having improved the quality and performance of PCBs overall.
Cost of processing and handling is reduced.
SMT components can be mounted on both side of the board.
Ability to fit a high number of small components on a PCB has allowed for much denser, higher performing, and smaller PCBs.
2.0mm Right-angle Dual Row female header, 2.0mm SMT Single row female header and 2.0mm SMT Dual row female header are Antenk`s SMT female headers.
Soldering Temperature for 2.0mm Pitch Female Headers
Soldering SMT female connectors can be done at a maximum peak temperature of 260°C for maximum 60 seconds.
Orientation/Pin-Type: Vertical (Straight) and Right-Angle
2.0mm pitch female headers may be further classified into pin orientation as well, such as vertical or straight male header or right-angle female header.
Vertical or Straight Female Header Orientation
One side of the series of pins is connected to PCB board in which the pins can be at a right-angle to the PCB surface (usually called "straight" or [vertical") or.
Right-Angle Female Header Orientation
Parallel to the board's surface (referred to as "right-angle" pins).
Each of these pin-types have different applications that fit with their specific configuration.
PCB Connector Stacking
For 2.0mm pitch female headers, the orientation is either offered as vertical or right-angle, which are options. Elevated sockets/female headers can be available upon request.
Profile Above PCB
This type of configuration is the most common way of connecting board-to-board by a connector. First, the stacking height is calculated from one board to another and measured from the printed circuit board face to its highest insulator point above the PCB.
Elevated Sockets/Female Headers
Elevated Sockets aka Stacked sockets/receptacles or Mezzanine are simply stacked female headers providing an exact distance requirement between PCBs that optimizes electrical reliability and performance between PCB boards.
Choosing this type of stacking configuration promotes the following benefits:
Connector Isolation - the contacts are shrouded preventing cable connection mishaps and good guidance for the mating header connectors.
For off-the-shelf wireless PCB module, stacking height is optimized with elevated sockets.
Offers superior strength and rigidity.
Polarisation prevents users from inverted insertion.
Single, Dual or Multiple Number of Rows
For a 2.0mm straight or vertical female header, the standard number of rows that Antenk offers ranges from 1 to 2 rows. However, customization can be available if 3, 4 or n number of rows is needed by the customer. Also, the number of contacts for the single row is about 2-40 pins while for dual row, the number contacts may vary from 2-80 pins.
Pin Material
The pins of the connector attached to the board have been designed with copper alloy. With customer`s demand the pins can be made gold plated.
Custom 2.0mm Pitch Female Headers
Customizable 2.0 mm pitch female headers are also available, making your manufacturing process way faster as the pins are already inserted in the headers, insulator height is made at the right size and the accurate pin length you require is followed.
Parts are made using semi-automated manufacturing processes that ensure both precision and delicacy in handling the headers before packaging on tape and reel.
Tape and Reel Packaging for SMT Components
Antenk's SMT headers are offered with customizable mating pin lengths, in which each series has multiple number of of circuits, summing up to a thousand individual part number combinations per connector series.
The tape and reel carrier strip ensures that the headers are packaged within accurately sized cavities for its height, width and depth, securing the headers from the environment and maintaining consistent position during transportation.
Antenk also offer a range of custom Tape and reel carrier strip packaging cavities.
