Precalentador PH300-TW

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.The Proton InteliTHERMTM non-contact spectral radiation wire temperature gauge is now available for use with new or existing preheaters.For 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.The dual-wire model supports two wires in parallel for simultaneous heating (each wire's pulleys rotate independently).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 (optional) InteliTHERM 'spectral radiation' temperature measurement available for greater accuracy in wire temperature measurement and control.Improves insulation adhesion to the cable and stripping characteristics, especially at high line speeds.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 200, 400, and 480 VAC.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, offering 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 issues in data and telecom 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 needed to maintain the required 'preset temperature,' regardless of wire size or production speed.The preheater is fully protected against phase loss or mains voltage drops.SpecificationsModelPH300-20-400-TWMaximum output power / kW20Three-phase supply voltage / VAC (line-to-line RMS)400SpecificationMinimumTypicalMaximumUnitsPulley root diameter294mmSolid wire diameter0.53mmStranded cable diameter3.2mmStranded cable cross-section8mm²Wire preheating temperature200°CContinuous wire tension (total for both wires)530NWire tension increase (at 1500m/min line speed)1NSupply frequency4765HzCable height98010001020mmWeight360kgOperating temperature545°CIngress protection (only cable entry/exit and pulley compartment)IP53Cable directionBidirectionalCable materialCopper / Aluminum / Copper-clad / SpecialStandard Interfaces4x Logic inputsFunctionElectromagnetic door lock (if installed)Emergency stopStart preheatingStop preheatingMax input voltage+24V4x Isolated relay outputsFunctionFaultStatusAuxiliaryEmergency stopMax contact capacity50VDC / 30VAC / 0.5ATemperature setpoint input0 to +10V user-scalable temperature control inputCommunication interfacesRS-232*An optional RS-232 to USB converter cable is available for connection to USB-equipped computers.OptionsCable loop current output: 0 to +10V output proportional to 0 to 2000A(rms) cable loop currentCommunication interfaces: PROFIBUSSolenoid door lock: Locks access door(s) until pulley movement has completely stoppedSocket height: Raises nominal line height to 43" (1092 mm)Twin doors: For use in tight factory spaces where the standard single door is too large (not applicable to PH160, PH450, or PH600)Technical Specifications / FeaturesModel: PH300-20-400-TWMaximum output power: 20 kWThree-phase supply voltage: 400 VACPulley root diameter: 294 mmSolid wire diameter: 0.5–3 mmStranded cable diameter: up to 3.2 mmStranded cable cross-section: up to 8 mm²Wire preheating temperature: up to 200°CContinuous wire tension: up to 530 NWire tension increase at 1500 m/min: up to 1 NSupply frequency: 47–65 HzCable height: 980–1020 mmWeight: up to 360 kgOperating temperature: 5–45°CIngress protection: IP53 (cable entry/exit and pulley compartment)Cable direction: BidirectionalCable material: Copper / Aluminum / Copper-clad / SpecialStandard interfaces: 4x logic inputs, 4x isolated relay outputs, RS-232Options: PROFIBUS, solenoid door lock, socket height, twin doors
