What Is an Extension Cord Reel?
An extension cord reel, also referred to as a cord reel or electric drum, serves as a practical tool that allows for the extension of electrical power via an extension cord.
The extension cord reel includes an extension cord, a drum for winding the cord, and an outlet plug on the drum’s side. This device allows for the extension of electrical power from a wall outlet by plugging the reel’s cable into the wall and extending the cord as needed.
Uses of Extension Cord Reels
Extension cord reels are indispensable on construction sites.
These sites often use electric drills, saws, and welders for cutting, drilling, and welding metal and wood. Although battery-powered tools are convenient, their use is limited by battery life. Tools powered from an electrical outlet are preferred for all-day use.
However, the limited length of a tool’s cord restricts its use, making extension cord reels essential for added flexibility.
Principle of Extension Cord Reels
While various specifications of extension cord reels exist, typically only a few are used at each job site due to storage and mobility constraints. One reel is often sufficient for most needs.
Specifications include cord length, generally ranging from 10 to 50 meters. Longer cords offer more convenience but are heavier and can pose a fire hazard if used while wound up due to heat accumulation in the drum. Conversely, shorter cords are lighter and safer to use but limit the range of operation.
