Trapezoidal aluminum shell resistor product features

Trapezoidal aluminum shell resistor product features

1. The resistance core is made of high temperature resistant ceramic flat tube, and the basic size of the ceramic is determined according to the size of the shell. 2. The resistance wire is uniformly wound with high-quality electric heating alloy wire, and the grade and model of the alloy wire are determined according to the resistance value. 3. Sealing material: Both ends are sealed with cement sand resin slurry (electronic insulating material), and when the cement material is semi-dry, an aluminum plate is used to seal the seal, so that the aluminum plate and the cement material are integrated to prevent sand leakage. 4. Shell: Made of high-quality industrial 6063 aluminum, the aluminum shell is anodized to fog silver, and it can also be sandblasted or brushed according to customer needs. 5. The lead wire adopts UL AWM3122 white textile silicone rubber high temperature wire (regular temperature resistance 200 degrees, maximum temperature resistance 250 degrees)
What is the use of gold aluminum shell resistors

What is the use of gold aluminum shell resistors

What is the use of gold aluminum shell resistors? Gold aluminum shell resistors have stable performance and low resistance value. The ambient temperature of gold aluminum shell resistors: -55℃~+170℃; Accuracy range: ±5%, ±2%, ±1%. The gold aluminum shell resistor changes its own resistance, thus playing the role of controlling the circuit. In the circuit analysis, the gold aluminum shell resistor can be used as a fixed value resistor and a variable value resistor. Gold aluminum shell resistors are made of nickel, chromium, alloy resistance wire wound iron and other resistance materials in alkaline heat-resistant ceramic parts, external heat, humidity, no corrosion and protective materials, again ceramic encapsulation, especially non-flame cement filler sealing , At present, the demand for gold aluminum shell resistors in the market is slowly expanding.
Features of high-power load resistance cabinets

Features of high-power load resistance cabinets

1. It is controlled by touch screen + PLC mode, with two modes of local control and PC control, and corresponding upper computer operation software is provided. 2. Inductive, capacitive and resistive load power can be combined arbitrarily, resistive 0.001KW to high power adjustable, inductive 0.001KW to high power adjustable, capacitive 0.001KW to high power adjustable. Accurately adjust the AC resonance point under the condition of three-phase voltage unbalance. 3. According to the testing requirements of performance parameters, the discharge power can be arbitrarily combined and set through the operation panel. 4. Simulate the resonance occurrence of AC power equipment, effectively and accurately detect the anti-islanding protection function of the grid-connected inverter. 5. Detect the working efficiency of various inverters, run at full load to large output power and load capacity. 6. Simulate various complex working environments and detect the comprehensive working performance of the inverter in various environments. 7. Resonance test: set inductive power consumption = capacitive power consumption, theoretically inductive capacitive reactive power cancels each other during resonance, reactive power = 0. 8. The minimum resolution of resistive load, inductive load and capacitive load is 1W, which can accurately simulate the occurrence of AC resonance and meet the needs of inverter debugging and testing. 9. Can measure a variety of data to meet the needs of inverter testing, including: resistive current, inductive current, capacitive current, voltage, current, frequency, power, apparent power, reactive power, voltage total harmonics, current Total harmonics, power factor, voltage waveform, the measurement data can be uploaded to the PC and the process record and storage function of the detection process data can be realized. 10. The measurement data can be uploaded to the computer and the process record storage function of the detection process data can be realized
