A 2.5mm 100-meter extension cable is a heavy-duty solution for extending power over long distances. The "2.5mm" refers to the cross-sectional area of the conductor, indicating its ability to carry a significant current. Typically, a 2.5mm cable can handle around 18-24 amps, depending on installation and insulation type.
These cables are often found on reels, making them easy to deploy and store. They usually feature durable PVC sheathing for protection against wear, tear, and weather, making them suitable for both indoor and outdoor use. Many come with multiple sockets and often include a built-in circuit breaker for overload protection, essential for safety when powering tools, machinery, or multiple devices simultaneously on construction sites, workshops, or at events.
