Self-regulating heating tapes consist of two parallel buswires, embedded semi-conductive self-limiting matrix. This means that the heating cable automatically responds to changes in ambinent conditions. With increase in temperature, the synthetic material expands by molecular force, and the connections between the carbon particles diminish, reducing the load. Conversley, as the temperture decreases, so the load increases as the connections between the carbon particles increases accordingly.
Thus, the heating power varies according to the temperature of the surface the heating tape is applied to. Self-regulating heating tapes will not overheat or burnout - even when overlapped.
