哪个app可以买北单 www.lazyf.tw RGS series are used on roofs to provide a continuous drain path for melted ice and snow to flow through the gutter and to the downspout. The self-regulating characteristic adjusts cable's heat output in accordance with the ambient condition. In snow and icy water, the heating cable operates at full power. As the snow melts and the water drains away, RGS self-regulates to half power. As it gets warmer, the power output will decrease to reduce energy consumption.
Designed for installing on inclined roofs with noncombustible tab shingles (such as asphalt shingles), metal or plastic gutters, downspouts, and/or valleys to melt ice and snow, provide a clear path for melted water to drain, and ultimately avoid the formation of ice dams and icicles.
