JDC established in 1996, we are the leader manufacturer for resistors in China .As the 16 years' development , not only for sales amount but also for the scale of enterprise.we are getting into the biggest manufacturer in South China .Now we own 2 branch factories : Shenzhen & Sichuan province .We have advanced production , inspection equipment , facilities and a perfect quality management system. All our products meet RoHS environmental protection standard and pass the quality system certification ISO9001
Due to the particularity of the use of the DC load box and its importance to the generator set toilet, we need to understand the following precautions when using the load box.
Current load case is the core of generator test system has been widely recognized in the market, the rapid growth in demand. Overall, mainly because the industry demand for generating set and the increasing demand for detecting unit for scientific maintenance.
The neutral point grounding methods commonly used in my country's power system are: the neutral point is directly grounded, the neutral point is not grounded, the neutral point is grounded through the arc suppression coil (resonance grounding), and the neutral point is grounded through the resistance.
Wire wound resistor series is one of the more commonly used resistors. The resistor body of wire wound resistor is resistance wire. The resistance wire is wound around the ceramic skeleton, the leads are connected, and the surface is coated with a layer of glass glaze or insulating paint.
Aluminum shell resistor, the shell is made of aluminum alloy (gold aluminum case), the surface has heat dissipation grooves, small volume, high power, high temperature resistance, strong overload capacity, weather resistance, high precision, standard low induction resistance, high stability, strong structure It has multiple adaptability and good flexibility, which is good for mechanical protection and convenient for installation and use.
