Three large UHV DC power transmission capacity to East China Power Grid exceeded 500 billion kWh
The three large UHV DCs of Fufeng, Jinsu and Binjin have accumulated more than 500 billion kWh of electricity to the East China Power Grid, effectively promoting the absorption of water and electricity in the southwest and alleviating the resource and environmental tension in the eastern region.
The UHV power grid is connected to the development of clean energy in the west and north, and the clean development of the eastern and central regions has become the strategic focus of the country's clean energy development. This is especially true for Sichuan Power Grid, which is rich in hydropower resources.
During the “Twelfth Five-Year Plan†period, it was a major opportunity for the development of Sichuan Power Grid to achieve a new leap. According to the State Grid Corporation's plan for UHV power grids, Sichuan is not only the most important delivery terminal of the State Grid, but also the main battlefield and main position for the construction of UHV power grids. During this period, Sichuan fully promoted the construction of three UHV DC transmission lines, opening up a fast track for hydropower delivery.
Since 2010, Fufeng, Jinsu and Binjin have been put into operation in succession. The new pattern of large-scale power transmission and large-scale power transmission has been formally formed. The transmission power of Fufu Line is 6.4 million kilowatts, the transmission power of Jinsu Line is 7.2 million kilowatts, and the transmission power of Binjin Line is 7.5 million kilowatts. Among them, the Binjin DC transmission project put into operation on July 3, 2014 is one of the largest DC transmission projects in the world with the largest transmission capacity, the highest voltage level and the highest rated current. It is also the world's first 8 million kilowatts and 8.4 million. UHV transmission project with kilowatts of overload transmission.
During the annual flood season, in order to fully absorb the clean water and electricity in Sichuan, the State Grid Sichuan Electric Power Company keeps the thermal power unit in a minimum mode of operation, giving priority to ensuring the full flow of water and electricity, and transporting clean water energy resources to the eastern load center. UHV has made Sichuan's clean water and electricity “out of the box†prosperous, and the hydropower generation capacity of Sichuan Power Grid has been well absorbed.
As of the end of July this year, Sichuan Power Grid has installed a total of 81.859 million kilowatts, of which hydropower installed capacity is 65.83 million kilowatts, hydropower generation is 13.799 million kilowatt hours, an increase of 5.05% over the same period of 2016. Calculated according to the calculation of 31,500 tons of standard coal per 100 million kWh of electricity, the accumulated amount of 508.8341 billion kWh of electricity delivered to East China is equivalent to saving 16 million tons of standard coal and reducing carbon dioxide emissions by 40 million tons.
The State Grid Corporation operating branch insists on paying close attention to safety production, firmly establishes the awareness of red lines, compacts and compacts safety production responsibilities, continuously strengthens safety production management, and ensures the safe and stable operation of the three UHV DCs. In the next step, the State Grid Operation Company will strictly implement standardization operations, deepen the lean management of equipment, continuously improve the intelligent management and control system for DC transportation inspections, and do a good job of keeping power on duty during the Spring Festival and annual maintenance after the holiday, and make every effort to ensure the safety of the stations under its jurisdiction. Stable operation, lay a good foundation for the continuous and stable delivery of Sichuan Electric.
Antenk battery holders are manufactured from UL rated 94V-O materials. Contacts made of high quality spring steel to assure reliable connections and allow contact resistance. Each contact is clearly marked with its polarity to assure proper battery insertion.
Lightweight and rugged, these PCB coin cell holders offer uniquely designed notched battery slot that assures quick and easy insertion and replacement of all major battery manufacturers' lithium coin cells.
Coin Cell Battery Holders
We have created a wide variety of coin cell battery holders for use in all types of devices, and from handheld medical devices to server motherboards we have solutions for any application. The ever increasing types, sizes, and sheer number of devices which use coin cell battery holders have been keeping us busy, and we have a similarly increasing selection of coin cell battery holder designs. After all, the perfect coin cell battery holder for a handheld medical device is going to be vastly different from the one for a server motherboard.
Lithium Coin/button Cell-Holders Battery Holders
Compact and vertical holders allow battery insertion and replacement from the top, making them ideal for high-density packaging
compact and vertical holders allow battery insertion and replacement from the top, making them ideal for high-density packaging, which maximizes board placement choices. The through-hole mount (THM) versions feature an "air-flow" support-leg design that facilitates soldering and quick battery insertion. The surface-mount (SMT) versions feature a "flow-hole" solder tail design for increased solder joint strength and are available on tape-and-reel.

Unique Coin Cell Battery Holders
Antenk has pioneered a large number of new styles of coin cell battery holders to suit the various needs of the electronics industry. Our Verticals are an excellent way to save space on a crowded board, while our Minis can save almost 3 mm in height above the PCB over traditional coin cell battery holders. Gliders are an excellent upgrade over coin cell retainers, offering more reliable connections while also having simple, tool-less battery replacements. Our newest technology is Snap Dragon, which adds a snapping cover to the traditional style of coin cell battery holders for increased reliability.
