Electrical tape is a type of insulating tape used in electrical applications to insulate wires and protect them from moisture, abrasion, and short circuits. Made from vinyl, rubber, or cloth, it is designed to be flexible and stretchable, allowing it to conform to different shapes. Electrical tape is typically available in various colors, with black being the most common for general use. Its strong adhesive ensures a secure bond, making it essential for safe and effective electrical work.
