China Power Cords for New Energy & Server Fields | Top Suppliers & Factory Solutions
In the new energy and server fields, plugs and power cords play crucial roles in ensuring the stable operation of equipment.
1 New Energy Field
A. Electric Vehicle Charging
1) Home Charging
AC charging cables with specific plugs are used for home charging stations. For instance, in many countries, a Type 2 plug is commonly used for AC charging at home. These power cords connect the household electrical outlet to the electric vehicle (EV) charging port. They typically operate at lower power levels, around 7kW for single-phase charging, which is suitable for overnight charging, allowing EV owners to conveniently charge their vehicles while at home.
2) Public Charging Stations
Slow Charging: Similar to home charging, slow-charging public stations also use AC power cords with corresponding plugs. They are often installed in parking lots of shopping malls, offices, and residential areas, providing a convenient charging option during daily activities.
Fast Charging: DC fast-charging stations require high-power DC charging cables. These cables are designed to handle large amounts of current to charge EVs quickly. The plugs used in DC fast-charging, such as the CCS (Combined Charging System) plug, can transfer power at much higher rates, sometimes up to 350kW, significantly reducing the charging time compared to AC charging.
B. Renewable Energy Generation
1) Solar Power Systems
In solar power plants or rooftop solar installations, power cords connect solar panels to inverters. These cords need to be resistant to environmental factors like UV radiation, high temperatures, and humidity. The plugs ensure a secure connection, allowing the direct-current (DC) electricity generated by the solar panels to be safely transmitted to the inverter, which then converts it into alternating-current (AC) electricity for use in the grid or in-house electrical systems.
2) Wind Turbines
Power cords and plugs are used to connect various components within a wind turbine, such as the generator, control system, and the power grid connection point. The plugs must be able to withstand vibrations, harsh weather conditions (including strong winds, rain, and cold temperatures), and ensure reliable power transmission from the generator, which produces electricity as the turbine blades rotate.
2 Server Field
A. Data Centers
1) Power Distribution
Server power cords are used to connect servers to power distribution units (PDUs). In data centers, where there are numerous servers operating continuously, different types of power cords are employed based on power requirements. For example, C13/C14 power cords with a 10A rating are commonly used for standard-power servers. These cords connect the server's power inlet to the PDU outlet, ensuring a stable power supply.
2) High-Power Servers
For high-power servers, such as those used for large-scale data processing or cloud computing, C19/C20 power cords are used. These can handle up to 16A of current, providing the necessary power for the high-performance operation of these servers. They are crucial for maintaining the continuous operation of data-intensive applications and services that rely on these servers.
B. Office and Enterprise Servers
In office environments, servers are often connected to standard electrical outlets using appropriate power cords and plugs. These cords ensure that the servers can run smoothly, providing services like file storage, email management, and internal network services for the enterprise. The plugs and power cords need to be reliable to prevent any disruptions to these essential business-related services.
