Precalentador PH450 Series

Product DetailsThe ProTHERMIC PH series is a complete range of high-frequency induction preheaters that incorporate the most advanced high-frequency solid-state technology. Wire preheating is an essential operation to achieve moisture removal from the wire, improve stripping characteristics, and prevent pinhole and bare patch failures.FeaturesFor induction preheating of solid and stranded copper, copper-clad, and aluminum wires up to 200°C (300°C for high-temperature models (-HT)) before insulation extrusion.Improves insulation adhesion to the cable and stripping characteristics, especially at high line speeds.Maximum power transfer rate to the cable EEE 96% (Electrical Energy Efficiency) ensures minimal losses and maximum utilization of available power.Uses a parabolic control algorithm to ensure a high degree of heating accuracy for all line speeds and wire sizes.Integrated InteliTHERM "spectral radiation" temperature measurement (optional) available for greater accuracy in wire temperature measurement and control.Preheats solid wires up to 4.5 mm in diameter and stranded wires up to 5.64 mm in diameter.Housed in robust enclosures to withstand harsh industrial environments.Controlled via an easy-to-use menu-based LCD interface display unit.Available with standard or optional communication interfaces.Available in different power models suitable for all budgets and line speeds.Available in three-phase supply voltage models of 400 and 480 VAC.IntroductionThe ProTHERMIC PH series is a complete range of high-frequency induction preheaters that incorporate the most advanced high-frequency solid-state technology. Wire preheating is an essential operation to achieve moisture removal from the wire, improve stripping characteristics, and prevent pinhole and bare patch failures.The Proton InteliTHERM™ non-contact spectral radiation temperature gauge is now available for use with new or existing preheaters. Proton preheaters have a high degree of accuracy during preheating, but for some applications where temperature stability and accuracy are critical, the use of the InteliTHERM™ SRTG device can further improve temperature stability. The InteliTHERM™ SRTG series connects directly to the preheater control module, providing rapid and precise feedback and temperature control. This makes operating the preheater as simple as setting the temperature and pressing "go".TechnologyThe short-circuit pulley rim is made of a special copper alloy with high electrical conductivity and good wear resistance.The insulating pulley is made of resin-bonded fabric, which has good wear resistance and low thermal conductivity to minimize heat loss between the cable and the pulley.The pulleys are mounted on double-row, low-friction ball bearings to minimize drag force (tension increase) on the wire as it passes through the preheater. Both pulleys are precisely machined to ensure uniform tension is applied to the wire, thus reducing SRL problems in data and telecommunications cable applications.The preheater is powered by a three-phase mains input, which is converted into a high-frequency supply by a specially designed inverter, whose output is automatically adjusted to supply the power required to maintain the required "preset temperature," regardless of wire size or production speed.The preheater is fully protected against phase loss or voltage drops in the power supply.SpecificationsModelPH450-20-400PH450-20-480PH450-25-400Maximum output power / kW202025Three-phase supply voltage / VAC (line-to-line RMS)400480400SpecificationMinimumTypicalMaximumUnitsPulley root diameter450mmSolid wire diameter14.5mmStranded cable diameter5.64mmStranded cable cross-section25mm²Wire preheating temperature200°CContinuous wire tension2005NWire tension increase (at 1500m/min line speed)1NSupply frequency4765HzCable height98010001020mmWeight500kgOperating temperature545°CIngress protection (only cable entry/exit and pulley compartment)IP53Cable directionLeft to right or right to left (see diagram below)Cable materialCopper / Copper-clad / Aluminum / SpecialStandard Interfaces*An optional RS-232 to USB converter cable is available for connection to USB-equipped computers.Options(Must be specified for installation at the time of manufacture; cannot be installed later)Cable loop current output0 to +10 V output proportional to cable loop current from 0 to 2000 A(rms)Communication interfacesPROFIBUSSolenoid door lockLocks access door(s) until pulley movement has completely stopped.Socket heightRaises nominal line height to 43" (1092 mm).Twin doorsFor use in tight factory spaces where the standard single door is too large (not applicable to PH160, PH450, or PH600)Technical Specifications / FeaturesMaximum output power: 20-25 kWThree-phase supply voltage: 400/480 VACSolid wire diameter: 1-4.5 mmStranded wire diameter: up to 5.64 mmWire preheating temperature: up to 200°C (300°C for -HT models)Weight: up to 500 kgOperating temperature: 5-45°CIngress protection: IP53 (cable entry/exit and pulley compartment)Communication: PROFIBUS, RS-232/USB (optional)
