An extension cord reel, also known as a cord reel or electric drum, is a convenient device that allows you to extend the power supply via an extension cord.
The extension cord reel has an extension cord, a drum around which the cord is wound, and an outlet plug in the center of the side of the drum. With this, you can extend the electricity obtained from the wall outlet by inserting the cable of the power reel into the outlet on the wall and extending the extension cord as far as the length of the cord allows.
Extension cord reels are a must-have item on construction sites.
Construction sites use electric drills, saws, and welders to cut, drill, and weld metal materials and wood. A wide variety of battery-powered power tools are available, so while battery-powered tools are convenient to carry, they cannot be used if the battery runs out. Tools that are powered by an electrical outlet are preferred for sites where work is performed throughout the day.
However, the length of the tool's cord limits the range of use, so extension cord reels are used when flexibility in tool use is desired.
Although there are various specifications of extension cord reels and it is ideal to use them according to the basic uses of the tools, in practice, a small number of extension cord reels, say one or two, are used at each job site, instead of purchasing several. This is because it is difficult to store and move several reels, and one reel is sufficient in most cases.
Extension cord reels specifications include cord length, which generally ranges from 10 meters to 50 meters. While longer cords are more convenient and easier to use, they are also heavier due to the weight of the cord. Also, since the cord heats up when current flows through it, if the cord is used while it is still wound, the heat builds up in the drum, causing an accident where it catches fire. The longer the cord, the more heat is generated, so you have to use it with the cord out, but if it is long, it will take effort.
On the other hand, a short cord is easier to use but limits the range of use.
