An electric reel is an extension cord equipped with a drum that allows it to be easily unrolled. The available models are distinguished by their type of cable and their options to meet everyone's needs.
Electric reels have different characteristics to know:
- they are equipped with a drum allowing the user to unroll the length of cable they need;
- they are equipped with multiple sockets allowing to connect various devices at the same time;
- models with galvanized steel or reinforced flanges are shock-resistant and are therefore suitable for use on a construction site;
- versions with flap sockets are classified IP 44 certifying their resistance to dust and water projection;
- the supported power decreases when the cable is rolled up due to overheating.
The available extensions differ by their type of cable:
- the length of the electrical cable varies from 5 m to 50 m;
- devices equipped with a H05VV-F cable with PVC sheaths are appreciated for their affordable price and are suitable for domestic use;
- H07RN-F cables with neoprene sheaths are suitable for humid environments and professional use;
- a cable consisting of 2 wires (2G) or 3 wires (3G) with a section of 1.5 mm² can support an electric current of 16 A and 3,500 W;
- a cable consisting of 2 or 3 conductors with a minimum section of 2.5 mm² is recommended for powering powerful devices.
Some options may be useful for added safety and comfort:
- a light indicator allows the user to know whether the sockets are live or not to avoid accidents;
- a thermal fuse protects connected devices from potential overvoltage;
- fixed hub versions unroll and roll up without having to unplug devices;
- automatic models unroll and roll up without any user intervention;
- the presence of a multi-socket block at the end of the cable optimizes comfort when working in confined spaces.
The choice of an electric reel mainly depends on the user's needs, particularly the power of the devices to be connected to the sockets and the use (professional or domestic).
