  • Thermal Power
    Thermal power is a power station in which heat energy is converted into electrical energy. In most cases, steam-driven turbines convert heat into mechanical energy, which is used as the middle of electrical energy. Water is heated, turned into steam, and drives steam turbines, which drive generators. After the steam passes through the turbine, it condenses in the condenser and then circulates to the heated place.

  • Wind Power
    Wind energy is a promising clean energy source. Wind turbine is the main power mainly equipment of wind farm, which converts wind energy into mechanical energy, and converts mechanical energy into electrical energy. The large and high-altitude operation of the fan is destined to be difficult to operate in the infrastructure and maintenance, and the main power supply, process control, network a communication of the fan equipment, the field equipment needs high-level anti-surge shock and safety protection, and improve the reliability and availability of the system and equipment.
