Yunnan cable manufacturers: wire and cable products are mainly divided into five categories

Yunnan cable manufacturers: wire and cable products are mainly divided into five categories 1. bare wire and bare conductor products The main features of these products are: pure conductor metal, no insulation and sheath, such as steel core aluminum stranded wire, copper aluminum bus, electric locomotive wires, etc. The processing technology is mainly pressure processing, such as melting, rolling, stretching, twisting/compression twisting, etc. Products are mainly used in the suburbs, rural areas, users of the main line, switch cabinets and so on. 2. The main features of such products as power cables are: squeezing (winding) a layer of insulating layer around the conductor, such as overhead insulated cables, or stranding several cores (corresponding to the phase line, zero line and ground line of the power system), such as overhead insulated cables with more than two cores, or adding a layer of sheath, such as plastic/rubber sheathed wires and cables. The main process technologies include drawing, stranding, insulation extrusion (winding), cable forming, armor, sheath extrusion, etc. There are some differences in the different process combinations of various products. The products are mainly used for the transmission of high-voltage electric energy in power generation, distribution, transmission, transformation and power supply lines, with large current (tens of amperes to thousands of amperes) and high voltage (220V to 500kV and above). 3. Yunnan cable manufacturers share the main features of wires and cables used in electrical equipment. The main features of such products are: many varieties and specifications, wide application range, 1kV

Maximum outgoing power of Northwest Power Grid reaches 8.11 million kW

The reporter learned from Northwest Power Grid Co., Ltd. on the 19th that since early March, the power transmission channel from Northwest China to Central China, North China, and East China has realized full-load cross-regional transmission for the first time, with a maximum transmission power of 8.11 million kilowatts, which can greatly alleviate the power shortage in Central China, North China, and East China power grids. According to the introduction of Northwest Power Grid Co., Ltd., starting from early March, the three 8.11 million-kilowatt power transmission channels of the Northwest Power Grid from Baoji in Shaanxi to Deyang in Sichuan, from Shaanxi to Lingbao in Henan, and from Ningdong to Shandong have begun to transmit power at full load across regions. These power will be used to ease the power shortage in Central China, North China, and East China power grids. According to statistics, cut

China Southern Power Grid has a power gap of 13 million kilowatts.

The National Development and Reform Commission stated on March 20 that in February this year, the country's maximum power limit load was 5.66 million kilowatts, a decrease of 870000 kilowatts month-on-month; the cumulative power limit was 1.29 billion kilowatt-hours, an increase of 0.64 billion kilowatt-hours. The power rationing provinces in that month were mainly concentrated in the five provinces (regions) of Guangdong, Guangxi, Guizhou, Yunnan, and Hainan under the jurisdiction of China Southern Power Grid. The maximum power rationing loads were 286, 169, 161, 92, and 180000 kilowatts respectively. Among them, Guangdong, Guangxi, Guizhou, and Yunnan are mainly affected by the drying up of incoming water, and the reduction of hydropower generation affects the implementation of the west-to-east power transmission plan; Hainan suffered a short-term and small amount of power rationing in late February due to unit failure.

Development of Photovoltaic Equipment in China in 2012

China's photovoltaic equipment manufacturing industry has a long history of development, the first crystal growth equipment was born in 1961. At the beginning of the 21st century, the rapid development of the photovoltaic industry in Europe, the United States and Japan under the support of policies triggered the market demand for silicon, silicon wafers and component production equipment, which greatly promoted the development of equipment manufacturing enterprises. China's photovoltaic equipment enterprises through the introduction, digestion and absorption of international advanced technology, continue to increase research and development efforts, and gradually have independent intellectual property rights of photovoltaic equipment. With the intensification of market competition and technological progress, the processing capacity, production efficiency and automation of photovoltaic equipment continue to improve.
