Introduction
The ProTHERMIC PH Series are a comprehensive range of High Frequency induction Preheaters featuring the latest advanced High Frequency solid state technology. Wire preheating is an essential operation to achieve elimination of wire moisture, improve stripping characteristics, and avoid pin hole and bare patch faults.
The Proton InteliTHERMTM Spectral Radiation non contact wire Temperature Gauge is now available for use with new or existing preheaters. Proton Preheaters have a high degree of accuracy during preheating, however for some applications when temperature stability and precision are critical the use of the InteliTHERMTM SRTG device can further enhance temperature stability. The InteliTHERMTM SRTG series connects directly to the preheater control module providing fast and precise temperature feedback and control. This makes operating the preheater as simple as just setting the temperature and pressing go.
Technology
The shorting pulley rim is manufactured from a special copper alloy that has high electrical conductivity and good wear resistance.
The insulating pulley is manufactured from resin bonded fabric which has good wear resistance and low thermal conductivity to minimise wire-to-pulley heat loss.
The pulleys are mounted on low friction, double row ball bearings to minimise the drag force (tension increase) on the wire as it passes through the preheater. Both pulleys are precision machined to ensure that uniform tension is applied to the wire, thus reducing SRL problems in data and telecommunications cable applications.
The preheater is powered from a 3-phase mains input, which is converted to a high-frequency supply by a specially designed inverter, the output of which is automatically adjusted to deliver the necessary power to maintain the required “Preset Temperature” regardless of wire size or production speed.
The preheater is fully protected against mains supply phase loss or brownouts.
