Grading cables
WebGrading Of Cables. Grading of cable is the process of achieving uniform distribution of dielectric stress or voltage gradient in a dielectric of cable. Voltage gradient or dielectric stress is maximum at the surface of the … WebFor cables of less than 50 feet of length, expect to pay $2 to $4 per foot. Beyond 50 feet in length, high-end heat cables range from $1.50 to $3 per foot. If your heat cable doesn’t ship with the clips needed to secure it to the roof, you’ll need to spend a few extra dollars for this hardware. Caution.
