The first public announcement of environmental impact assessment for the renovation, expansion, and relocation project of 8000 high and low voltage switches per year


The environmental impact assessment of the reconstruction, expansion and relocation project with an annual output of 8000 sets of high and low voltage switches of Jiyuan Xinke Mining Electric Co., Ltd. has been started. According to the provisions of the Interim Measures for Public Participation in Environmental Impact Assessment, the environmental impact assessment of the project is publicized as follows, and we hope you will actively participate and put forward valuable suggestions.

Increasing enthusiasm for purchasing domestic thermal coal


Port steam coal: Qinhuangdao Port coal price stability: Qinhuangdao Port coal price: 6000 kcal=639 yuan/ton, 5800 kcal=625 yuan/ton, 5500 kcal=595 yuan/ton. The price of steam coal in Port of Guangzhou is temporarily stable. The price of domestic trade coal in Port Q5500 is increased by 715 yuan/ton, the price of domestic trade coal in Port Q5000 is 610 yuan/ton, and the price of Indonesian coal in Port Q3800 is 445 yuan/ton. The market turnover is average.

Introduction to basic knowledge of explosion-proof motors


1.1 Explosion proof electrical equipment: Electrical equipment that, under specified conditions, will not cause ignition in the surrounding explosive environment.1.2 Explosive mixture: A mixture of combustible gases, vapors, mist, dust, or fibers with air between the upper and lower limits of explosion.1.3 Maximum surface temperature: The maximum temperature reached by any component or surface of electrical equipment that may ignite an explosive environment when operating under adverse operating conditions within the specified range.
