More Information
Summary:The low-resistance heating wire comprises a plurality of bundles of glass fiber yarns and at least one strand of first resistance wire which are arranged in the same direction to form a core body; at least one strand of second resistance wire is wound on the periphery of the core body and is wound into a spiral coil shape; the heat-conducting outer wire skin is used for absorbing heat of the first resistance wire and the second resistance wire and uniformly transferring the heat outwards; the total resistance value of the first resistance wires is adjusted by means of parallel connection of the first resistance wires with the same resistance value or different resistance values. When a plurality of strands of resistance wires with the same or different resistance values of the first resistance wire are connected in parallel for use, a lower and more accurate resistance value can be obtained through adjustment. The precision of the second resistance wire is adjusted through the width of the wire winding pitch
