1000W 10 Ohm J High Power Ceramic Tube Wirewound Resistors
Structure:
1. High Power,small size & fast heat dissipation,multi-tap and non-inductive winding are available.
2. Resistors feature nickel-copper, nickel-chrome or stainless steel wire wound in a double helix around the center core, depending on size and model. All have ceramic cores with a spiral groove to grip thecoiled wire. The 90° flat bus style terminals are corrosion resistant stainless steel.Other mounting options are available.
Features:
1. The product has the characteristic with solid structure,small volume and high power.
2. It is an ideal product in high impact and long-term load environment & also be applied to the solution of load banks.
3. The resistance wire of high power resistors select iron chromium aluminum,nickel chromium wire or constantan wire with high temperature resistance, stable electrical performance and small temperature drift coefficient.
