In the tide of deepening the reform of power system, China International Power Group Co., Ltd. has become a super large enterprise with the whole business chain integrating power planning, survey, design, construction, general contracting, project management, equipment, investment and operation, and also a new force in the field of EPC Construction of power Engineering in China. Through professional management, China International Power Group aims to minimize the investment control and maximize the quality control of power construction, so as to maximize the cost performance of power construction project management and achieve the objectives of power construction project management.

Photovoltaic power generation uses photovoltaic effect of semiconductor interface to convert light energy into electricity directly It's a technology that can be used. It is mainly composed of solar panel (module), controller and inverter, and the main components are composed of electronic components. After the solar cells are packaged and protected in series, a large area of solar cell modules can be formed, and then with the power controller and other components, the photovoltaic power generation device is formed.

Wind power generation refers to the conversion of wind kinetic energy into electric energy. Wind is one of the energy sources without pollution. And it's inexhaustible, inexhaustible. For the coastal islands, grassland and pastoral areas, mountainous areas and plateau areas with water shortage, fuel shortage and inconvenient transportation, it is very suitable and promising to use wind power generation according to local conditions. As the most competitive renewable energy, the relatively high cost of wind power is still the key factor restricting its future development. To make wind power replace a lot of fossil fuels, it still needs to be cheaper.

Hydroelectric power system uses rivers, lakes and other water with potential energy at high places to reach low places, converts the potential energy contained in them into kinetic energy of water turbine, and then uses the water turbine as the driving force to drive the generator to generate electric energy. In a sense, hydropower is a process in which the potential energy of water is transformed into mechanical energy and then into electrical energy. Due to the low voltage of the power generated by the hydropower plant, the voltage must be increased through the transformer before it is transmitted to the substation in the user concentrated area by the empty transmission line, and finally reduced to the voltage suitable for the household users and factory electrical equipment, and then transmitted to the factories and families by the distribution line.

With the rapid development of economy and society, the scale of power grid is expanding day by day. At the same time, extreme weather and natural disasters occur frequently, which pose a great threat to the safe and stable operation of power grid. At this time, power grid construction enterprises play a major role in emergency rescue. Once damage or failure occurs at the rescue site, if it can not be repaired in time, it is bound to affect the emergency rescue action and reduce the rescue delay effect Rate. Emergency repair refers to the use of emergency diagnosis and repair technology to quickly repair the equipment failure or damage. It is of great significance to study the characteristics of emergency repair, strengthen the construction of emergency repair force, and master convenient emergency repair methods to improve equipment support capability.

Social urbanization has become a trend, and the continuous development of urbanization is bound to put forward higher requirements for the construction of public infrastructure on which the city depends for its existence and normal operation. As far as urban power grid is concerned, which is an important part of modern urban public infrastructure, the main problem we are facing is how to properly solve the contradiction between the rapid growth of power load and the increasing shortage of power supply point and power channel resources, the living space of people's green environmental protection and the requirements of urban environment. It is undoubtedly an effective solution to transmit power in the form of cable in the city There is no solution. At the same time, the tunneling and networking of urban power grid, which is accompanied by the power transmission cable, will become the characteristics and development direction of urban power grid in modern society, especially the super large international urban power grid.

China International Power Group has a number of core technologies (patents and construction methods) for urban pipe network construction, and has a lot of practical experience in the non excavation field of small and medium-sized professional pipe network and comprehensive pipe gallery construction.

Guangdong Hefa iron tower Co., Ltd., a subsidiary of China International Power Group, is a large-scale enterprise specializing in the production of all kinds of transmission line steel towers, telecommunication iron towers and steel structures. It has a team of experienced employees, which provides solid support for the development of the enterprise.
