The aluminum shell resistor adopts high heat dissipation aluminum alloy shell and high temperature resistant material as the resistor matrix, which is filled with high insulation and incombustible filler. The resistor matrix is closely combined with the resistance wire and metal shell, and has high stability and thermal conductivity. It has the advantages of fast heat dissipation, vibration resistance, high power, strong overload resistance, small size, convenient installation and beautiful appearance. It is suitable for harsh industrial control environment and is an ideal supporting product for electronic power. Widely used in inverter braking, elevators, rolling mills, cranes, wire drawing machines and load aging tests. (Please indicate the guide type or harness type when ordering)
