If your pcb lead time affected by recently energy curtailment? Guangdong has made all-out efforts to cope with the recent power supply shortage caused by high temperatures and growing electricity consumption of secondary and tertiary industries. In Guangdong, when the temperature is between 31 to 37 degrees Celsius, the electrical load grows by two to three million kilowatts for each increasing degree Celsius of temperature. Since early September, under the influence of a subtropical high and two typhoons, the province has been seized by hot and dry weather that brought a surge in power consumption. As of Thursday, the highest electric load of Guangdong reached 141 million kilowatts, rising 11 percent more than last year. Meanwhile, the electricity demand has also increased rapidly this year, especially from secondary and tertiary industries that are currently in a peak season of orders. From January to August, the electricity consumption in Guangdong was 525.273 billion kilowatt-hours, up by 17.33 percent year-on-year, while that of secondary and tertiary industries has risen respectively by 18.30 percent and 23.13 percent. However, tight primary energy supplies, rising fuel prices, possible intermittent failures in peak-hour power generation facilities and other factors have affected the power suppliers’ generation capacities that resulted in power supply shortages. Thus far, many cities in Guangdong have initiated emergency plans to cope with the tight power supply. Industrial enterprises are required to operate only during off-peak hours for four or five days a week, which has impacted their normal operation. To solve the problem, Guangdong has made effort to guarantee sufficient thermal coal and natural gas supplies to meet power generation needs and urged power plants to store sufficient fuels and other materials needed for power generation and to ensure the stable operation of peak-hour generating sets. It has also advanced the construction of key power supply projects to ensure that the projects are put into operation as scheduled. Also, it has organized power generation and power grid enterprises to carry out tighter checks and maintenance on key devices and circuits to ensure safe and stable operation of the facilities. Also, it will coordinate the transmission of electricity from western China to Guangdong. Power grid enterprises are also required to improve electrical load prediction in accordance with weather reports. Government departments are required to work with enterprises to implement power-using plans and guide the enterprises to adjust production plans so as to guarantee power supplies for residents, the agricultural sector, key public institutions and public services. Industrial enterprises are required to follow local plans in response to electricity supply shortages. Local governments should establish special work teams with power supplying enterprises to inspect the industrial enterprises and coordinate services. The...

Classification characteristics 1000 series Representing 1050, 1060, the 1000 series aluminum plate is also called pure aluminum plate. Among all the series, the 1000 series contains the most aluminum, and the purity can reach more than 99.00%. Because it does not contain other technical elements, the production process is relatively simple and the price is relatively cheap. It is currently the most commonly used series in conventional industries. Most of the products circulating on the market are 1050 and 1060 series. 5000 series Represents the 5052, 5005, 5083, and 5A05 series. The 5000 series aluminum plate belongs to the more commonly used alloy aluminum plate series, the main element is magnesium, and the magnesium content is between 3-5%, which is also called aluminum-magnesium alloy. The main features are low density, high tensile strength, and high elongation. In the same area, the weight of aluminum-magnesium alloy is lower than other series, so it is often used in aviation, such as aircraft fuel tanks. In addition, it is widely used in conventional industries. Its processing technology is continuous casting and rolling, which belongs to the hot-rolled aluminum plate series, so it can be used for deep oxidation processing. In my country, the 5000 series aluminum plate is one of the more mature aluminum plate series. 3000 series Represents the 3003 etc. The strength is about 10% higher than 1060, and the formability, weldability, and corrosion resistance are all good. Used for processing parts that require good formability, high corrosion resistance and good weldability, or work that requires these properties and requires higher strength than 1XXX series alloys, such as kitchenware, food and chemical product processing and Storage devices, tanks and tanks for transporting liquid products, various pressure vessels and pipes processed with thin plates, general utensils, heat sinks, makeup boards, photocopier drums, and ship materials

According to the latest China Electricity Council data, electricity consumption during the first seven months of this year soared by 15.6 percent year-on-year to 4.7 trillion kilowatt-hours. [Photo/IC] The ongoing controls on the use of electricity in some regions of China are set to ease off, as government efforts to contain the coal price surge and improve coal supplies for power plants are expected to improve the electricity supply and demand situation, experts said on Monday. They also said a better balance will be ultimately achieved among electricity supply, carbon dioxide emission controls and economic growth targets, as China moves toward a greener electricity mix to fulfill its commitment to carbon dioxide emissions goals. Measures to reduce electricity use in factories are currently being enforced in 10 provincial-level regions, including the economic powerhouses of Jiangsu, Guangdong and Zhejiang provinces. Electricity supply problems have also resulted in blackouts for some household users in Northeast China. "There is a nationwide electricity shortage to some extent, and the main cause is greater-than-expected electricity demand growth driven up by earlier economic recovery and higher prices for energy-intensive products," said Lin Boqiang, director of the China Center for Energy Economics Research at Xiamen University. "As more measures are expected from the authorities to secure power coal supplies and frustrate the coal price surge, the situation will be reversed." According to the latest China Electricity Council data, electricity consumption during the first seven months of this year soared by 15.6 percent year-on-year to 4.7 trillion kilowatt-hours. The National Energy Administration has held conferences on ensuring sufficient supplies of coal and gas in the coming winter and spring, especially for power generation and household heating. Lin said that the surging prices of energy-intensive products, such as steel and nonferrous metals, have contributed to the rapid growth in electricity demand. Zeng Ming, head of the Internet of Energy Research Center at North China Electricity Power University, said the central authorities have already started taking measures to secure coal supplies and stabilize coal prices. As clean and new energy is expected to play a bigger and long-term role in China's energy mix than coal, coal-fired power will then be used to balance the grid rather than to meet baseload need, Zeng said.
