The reactive power compensation (filtering) module is generally composed of capacitors, reactors, contactors, fuses, connecting busbars, wires, terminals, etc., and can be easily assembled into various reactive power compensation (filtering) devices, and can also be used as Expansion module for installed compensating devices. The emergence of modules is a major change in reactive power compensation and filtering devices, and it will be the mainstream of the future market, and it is an improvement of the concept of service. Easy to expand, easy to install, compact structure, simple and beautiful layout, complete protection measures, such as overvoltage, undervoltage, overheating, harmonics and other protections, choose engineering and electrical module products, which is a unified comprehensive solution for design institutes, complete sets of manufacturers and users. type service platform.
