How to choose the right extension cord? Onninen expert advice
When choosing an extension cord, there are a few key factors to consider. The length of the cord is the first thing to consider. An extension cord that is too short can restrict mobility. An extension cord that is too long can be impractical and a tripping hazard.
Another important parameter is the cross-section of the wires. Extension cords 3x1.5 mm² are suitable for most home applications. For devices with higher current consumption, we recommend extension cords 3x2.5 mm². They provide better power transfer parameters.
Our experience shows that it is worth investing in high-quality extension cords. Cheap substitutes often do not meet safety standards. They can pose a threat to users and connected devices. Products from renowned brands such as F-Elektro or Qoltec guarantee safety and reliability.
Practical applications of extension cords in various industries
In our daily practice, we observe various uses of extension cords. In construction, durable drum extension cords are essential. They allow for the free use of power tools on the construction site. Power strips with surge protection are popular in offices. They protect valuable electronic devices from voltage spikes.
Recently, we used specialist industrial extension cords for a large shopping centre project. They provided safe power for many points of sale. Extension cords with a thicker 3x2.5 mm² wire work well in car workshops. They enable the connection of energy-intensive diagnostic devices.
Many customers ask us about extension cords for outdoor use. In such cases, we recommend models with H07RN-F insulation. They are resistant to weather conditions and mechanical damage. They work perfectly in gardens, on terraces or during renovation work outside buildings.
In the case of office reorganization, we most often recommend extension cords. They allow for flexible arrangement of workstations. They also provide easy access to sockets for many devices at the same time. Models with a switch allow for convenient disconnection of the power supply after work.
We often come across questions about extension cords for specialist applications. In laboratories and medical facilities, we use extension cords with additional grounding. They provide the highest level of safety for sensitive equipment. In the food industry, we use models with a splash guard. They protect electrical connections from moisture and contamination.
