250V 14AWG White C19 to C20 Power Cord 1m 2m 3m Power Extension Cord for Computer
1. Basic Definition
The C19 to C20 power cable is a high-power power cable that complies with the IEC 60320 standard and is used to transmit power in a 16A~20A high current environment. Its two ends are:
C19 (female): plugged into the power input interface of the device (such as server, UPS).
C20 (male): connected to the output of the power distribution unit (PDU) or industrial power supply.
This cable is designed for high-power devices and is commonly found in data centers, industrial machinery, and high-end network equipment.

Compared with other common interfaces:
C13/C14: Smaller size, suitable for devices below 10A (such as ordinary PCs, monitors).
C15/C16: High temperature resistant (120°C), used for electric kettles and industrial heating equipment.
C19/C20: Designed for high-power equipment (such as servers, data center PDUs).
3. Cable structure and materials
Conductor: High-purity oxygen-free copper (OFC), which reduces resistance and heat generation.
Insulation layer: flame-retardant PVC or rubber (temperature resistance above 105°C).
Sheath: wear-resistant and anti-pulling design, suitable for computer rooms or industrial environments.
Grounding protection: 3-core design (live wire L, neutral wire N, ground wire PE) to ensure safety.

4. Main advantages
High current support: 16A~20A, meeting the needs of 3000W~5000W high-power equipment.
High temperature resistance: materials above 105°C, suitable for long-term high-load operation.
Safety certification: UL, CE, IEC 60320 certified, in line with international electrical safety standards.
Anti-interference: Some models are equipped with a shielding layer (STP) to reduce electromagnetic interference (EMI).
5. Typical application scenarios
Data center: Connect rack-mounted servers and storage devices to PDU.
Industrial equipment: Medical imaging equipment (MRI), large machinery, power control systems.
Network communication: High-end switches (such as Cisco Nexus series), routers.
Broadcasting and stage equipment: High-power audio, lighting control systems.
6. Purchase considerations
Current matching: Confirm the power of the equipment (such as 20A equipment needs to use 20A cable).
Cable length: Standard wire can be selected for short distance (1~2m), and thick wire diameter (such as 4mm²) is required for long distance.
Temperature resistance requirements: Silicone sheath (resistant to 120°C or above) is selected for high temperature environment.
Certification standards: UL/CE certified products are preferred to ensure safety.
7. Frequently Asked Questions (FAQ)
Q1: Can C19 and C20 be mixed with other interfaces?
No! C19/C20 is a dedicated high-power interface and is not compatible with C13/C14.
Q2: How to distinguish between C19 and C15 interfaces?
C15/C16 has grooves (high temperature resistance), C19/C20 is square and larger (high current).
Q3: Does it support customized length and color?
Yes, it can be customized from 1m to 10m in length, and common colors are black, gray, and blue (for room identification).
Summary
C19 to C20 power cables are key components for high-power power transmission and are suitable for data centers, industrial and network equipment. When choosing, you need to pay attention to current, wire diameter, temperature resistance and certification to ensure safe and stable power supply.



Using thickened oxygen free copper wire core effectively reduces resistance and makes the circuit less prone to overheating. Simultaneously coated with a fireproof layer, it remains safe and durable even in high-temperature and dry environments. Bold thread body, sturdy and resistant to bending, will not break after long-term use.
