Power Cables
29 products
Power cables are essential components that safely transmit electrical energy from a source to a device or between systems. From hobby electronics to industrial setups, these cables cover a wide range: AC mains connections, DC power distribution, battery links, and extension cords. Our category includes standard IEC C13/C14 power cords, 5.5mm DC barrel jack cables, high-current silicone test leads, surge-protected versions, and multi-outlet power strips.
Where to Use Each Type of Power Cable?
- AC Power Cords (IEC/NEMA): Common for connecting computers, monitors, printers, and industrial machinery to the mains. C13 (female) to C14 (male) connectors are standard, while NEMA 5-15P plugs vary regionally.
- DC Barrel Jack Cables: Used with Arduino, Raspberry Pi, security cameras, LED strip drivers, and low-voltage devices carrying 5V, 9V, or 12V. The tip diameter (2.1mm, 2.5mm) and inner/outer dimensions must match the socket precisely.
- Extension Cords: Multi-outlet, grounded, or fused models for labs, workshops, or field use. The conductor cross-section should be chosen based on total load current.
- Silicone Test Leads: Withstand high temperatures and constant flexing, making them ideal for soldering stations, heated beds on 3D printers, and other moving systems.
Key Considerations When Selecting a Power Cable
First, determine the operating voltage (AC/DC) and maximum current draw. The wire gauge (AWG or mm²) directly affects ampacity; undersized cables may overheat and pose a fire hazard. Verify that the connectors mate correctly with both the device and the power source. In noisy industrial environments, shielded cables reduce interference; for harsh conditions, silicone or TPE insulation outperforms standard PVC. For long cable runs, compute voltage drop and increase the cross-section if necessary. Look through the technical specifications on each product page for instant access to these parameters.
