Standard

Construction

Electricity Floor Heating

N –Heating Conductor

18、19—Heating Power per meter (W/m)

R— Core Numbers (R or 1R means Single Core, 2R means two cores)

For Example:SNN-220V—19/R 

Means: 220V Single Core Heating Cable with 19 watts per meter

For example: SNN-220V—18/2R

Means: 220V Two Cores Heating Cable with 18 watts per meter
