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.

PU / ESS fuses are products that have been invented to protect the latest developments in the field of energy storage and transition and for that, we takes references from all leading international industry and quality management standards, IEC 60269,GB/T 13539,UL248 and IATF 16949.
Determine the following parameters,Rated Voltage,Rated Current,Dimensions and Wiring, overload capacity, shall help you in selecting the correct PU/ ESS fuse for your application 

In PV systems consisting of arrays with N>4 module strings fault current can easily exceed the operating current. The current can reach a level that can cause overheating and damage of wire insulation.

To ensure the best possible protection for the system and people working on the equipment, each string of solar panels MUST be protected with one fuse on each "+" and "- " terminal.

These fuses will only isolate the fault string. So the rest of the PV system can continuously generate electricity.

When a fault occurs in the DC circuit of the PV system the absence of natural zero crossing makes the interruption of DC fault more difficult than the inte interruption of AC faults as only the fuse are will force the current to decrease to zero.

Over-Current fuses, are innovative protective components designed for surface mounting on circuit boards. They offer several advantages over traditional through-hole fuses, including a smaller size and compatibility with automated manufacturing processes. This compact design allows for more efficient use of space in electronic devices, making them ideal for modern applications.
The primary function of OC fuses is to safeguard electronic equipment from damage caused by overcurrent conditions. They achieve this by utilizing a thermal cutoff mechanism that interrupts the circuit when excessive current flows through. This rapid response not only protects sensitive components but also minimizes the risk of fire hazards, ensuring the safety and reliability of the device.

Overtemperature fuses are critical safety devices used to protect electrical equipment from overheating. They are primarily categorized into two types: OT-F (one-time fusible temperature fuse) and OT-S (resettable thermal switch). 
The OT-F fuse is designed to permanently disconnect the circuit when the temperature exceeds a predetermined threshold. This one-time use characteristic makes it ideal for applications where a single failure point is acceptable. Once the OT-F fuse has blown, it must be replaced to restore functionality. This type of fuse is widely used in LED lighting,Transformers,Electronic Components,Large Household Appliances,Small Household Appliances,Electric Heating Appliances,and motors.
On the other hand, the OT-S fuse operates differently. It is a resettable thermal switch that interrupts the circuit when the temperature rises above a specified limit. However, once the temperature returns to a safe level, the OT-S automatically resets, allowing the circuit to reconnect without the need for replacement. This feature makes OT-S fuses particularly suitable for applications like LED Lighting, Transformer, Motor,Battery,Hair Dryer,Heater,Oven and charger. 

USB Type-C connector have been increasingly widely used in smart phones, Tablet PC, notebook, power bank, Smart wearable and other devices. Users benefit from its thin shape, up to 1OOW power transmission, support for forward and reverse plug and other advantages, but the overheat of connector often happened in the use easily leads to smoke or even burn. For example , once there is foreign body such as metal shavings, water stains ,hair and the others in the connector which have narrow needle design often cause Vbus and GND form a micro-short circuit .Therefore,the Type-C overheat protection becomes very necessary, Lucky Pioneer have launched both SBP and PPTC overheating protection solution.
