● Features & Structure


1. Product features:

High power, fast heat dissipation, high shock resistance, high stability, long service life, can brake frequently and instantaneously, can work for a long time, resistance value will not change too much, product consistency is high.

2. Product structure:

1) The core parts of the resistance core are made of insulating and high temperature resistant materials as the resistance framework, evenly wound with high-quality alloy wires, and sealed with high-quality and high thermal conductivity organic quartz sand, so that the metal aluminum shell and the core parts of the resistance are closely combined into a solid entity, free from the influence of external air and dust, It has high stability and thermal conductivity.

2) The aluminum shell is made of high-quality industrial 6063 aluminum, and the surface is treated with high-temperature anodizing silver mist or bright silver to achieve better appearance and insulation heat dissipation effect.

3) According to the resistance to bear different current size, the leading end is connected with high-quality high-temperature braided wire (no fuzzing, no allergy) or copper guide, stainless steel guide, which is convenient for customers to connect at will.

4) We have 46 aluminum shell models of different styles to facilitate customer selection; Can accept a variety of non-standard customization, all-round to meet customer needs.

3. Application fields:

Inverter, servo motor, servo driver, power load, elevator, lifting, medium frequency furnace, electric furnace, induction heating equipment industry, new energy vehicle manufacturing, wind power pitch system, wind power electronic control system and converter, solar photovoltaic inverter industry, small and medium-sized wind turbine (including grid connected / off grid type), medical equipment Machinery industry (such as paper machine), communication industry, rail transit, railway locomotive, power system, fan load, mining equipment, transformer, CNC machine tool, reactive power compensation device, laser industry, aviation, shipbuilding, military industry, State Grid, engineering supporting, major universities and design and research institutes.
