The calculation of short-circuit current mainly provides a basis for the equipment design, power grid planning and design, and operation control of the electrical distribution system. Its main purposes are as follows:   (1) The selection of electrical equipment parameters is usually related to the thermal effects of the electrical force and short-circuit current received […]

In this post, we will list all common questions about an OPGW fiber , which will make you have a better understanding of what an OPGW fiber is. 1. what is an OPGW Fiber there is an opitcal unit stranded together with a traditional grounding wire, and the optical unit used to house optical fiber

The incoming reactor is used for anti-interference to prevent mutual interference between the frequency converter and other equipment; The outlet reactor is used for filtering, and the carrier frequency of the frequency conversion is generally between 2 and 10 khz, which can make the output waveform smoother when used for filtering; The incoming reactor is
