Wire wound resistor
Wire-wound braking resistors can be suitable for rugged applications. Two terminal extensions are fixed on both ends of a ceramic tube on whose surface winds wave-shaped alloy resistance wire and a high temperature resistant and fireproof coating are applied. The ceramic tube can function as resistance wire skeleton and heat radiator as well. Key Features: 1.Long term high stability 2.non-inductive or inductive type options 3.high operating voltage(up to 1.2KV) and high power ratings(up to 15KW) 4.terminals suitable for soldering or bolt connection Characteristics: 1.Rated power: 50W-15KW, based on 25℃ free air rating 2.Resistance values: from 1Ω to as high as 10 KΩ( to 100 KΩ on request) 3.Temperature Coefficients:25,50 and 100ppm/℃ or as required 4.Operating Temperature:-55℃ to +225℃ 5.Insulation Resistance: >1000MΩ (500V 25℃ 75% relative humidity) 6.Dielectric strength: >3.0KV 50Hz 1min(25℃ 75% relative humidity) 7.IP protection: IP00, IP20 or as required 8.Element material: OCR25AL5/CrAlFe/CrNi/CuNi 9.Lead material: Brass Caps(lug terminations available) 10.Encapsulation: Silicone conformal coating Application: 1.simulation load testing, capacitor charging & discharging, 2.automation control , inverter's energy loss brake, 3.crane systems, various steel mill applications and transit applications, neutral grounding. 4.filter,electrical machinery general use, available through distribution
