Industry Application and Product Selection

The environment and function of an electrical device profoundly influence the type of AC power cord it requires. A simple two-prong cord for a lamp cannot be used for a high-demand server, nor can a standard cord withstand the extreme conditions of a solar installation. Choosing the wrong power connection is a technical failure waiting to happen. Dongguan Toongyean Power Connection Co., Ltd. (Toongyean-Tech) provides this expert power cord selection guide to help manufacturers match the right cord to the right application, ensuring compliance, safety, and optimal performance across major industries.

Home Appliance Power Cords must prioritize durability, safety compliance, and aesthetic appeal, as they are used in high-traffic residential settings.

Safety Focus (CCC/VDE): All domestic Chinese appliances require CCC certification, while exports to Europe require VDE certification. We ensure compliance with flame retardancy standards (e.g., VW-1) for indoor safety.
Insulation and Flexibility: Appliances like vacuum cleaners or blenders require highly flexible cables (often utilizing rubber or TPE jackets) that resist twisting and repeated bending without cracking.
Grounding Necessity: Devices with metal casings, such as refrigerators and washing machines, strictly require three-prong power cords for proper grounding, which is critical for preventing shock hazards. Lower-power, double-insulated devices often use two-prong configurations.
Key Products: CEE 7/7 (European Schuko) and NEMA 5-15P (US Standard) plugs are common, paired with IEC 60320 C13 or C5 connectors.

For servers, computers, monitors, and networking devices, the IT Equipment Power Cord needs to focus on electrical stability, noise reduction, and high reliability.

Noise and Interference: In sensitive IT environments, proper shielding within the cable is vital to prevent electromagnetic interference (EMI) from disrupting data transmission.
Current Capacity (Amperage): Server racks often require heavy-duty cables (e.g., 14AWG or $2.5\text{mm}^2$) to safely manage high current draws. Power cord current capacity calculation must be precise to avoid overheating and voltage drops across long runs.
High-Temperature Operation: Internal power supply units (PSUs) often run hot. Cables must be specified with high-temperature ratings (e.g., $90^\circ\text{C}$ or $105^\circ\text{C}$ jacket ratings) to maintain integrity in confined enclosures.
Key Products: IEC 60320 C13 and C19 connectors are industry standards for IT hardware due to their secure fit and rating capability.

New Energy Power Cables (e.g., for EV charging stations, solar inverters, battery storage) face the toughest operating environments, demanding extreme durability and specialized material science.

Environmental Resistance: These cables must withstand UV radiation, extreme temperature fluctuations, exposure to oil, and constant abrasion. Materials like specialized rubber or TPE are preferred over standard PVC.
High Voltage/High Current: EV charging and industrial systems operate at significantly higher power levels. The cables must handle high DC or AC voltages, necessitating superior insulation thickness and material quality.
Flexibility and Fatigue: Charging cables, in particular, are frequently coiled and uncoiled. They require exceptional flex life to prevent internal conductor breakage over time.
Key Products: Custom terminal connections, specialty heavy-duty plugs, and cables with IP-rated ingress protection.
