And its structure leads to the increase of the heating element’s length in each circuit. On site, it reduces the possibility of circuit damage by bending the cable. In this structure, the glass yarn supports the heating elements. It has the advantages of constant wattage heating cable and strengthens the disadvantages. 1 meter forms one zone, and parallel electric circuits are made. But instead of winding the bare Nichrome heating element itself, glass yarn is winded by Nichrome heating cable first, and they together winds the conductor. Its structure is similar to the constant wattage heating cable.
