Safe and reliable operation of the electricity distribution system directly concerns the safety of us. Shaanxi XD Hi-Tech Medium and Low Voltage apparatus Co. Ltd. (hereinafter referred to as "XD Hi-T") by virtue of the distribution of its experience, high-performance products ranging and rich mature experience in distribution projects, the successful launch of a complete low-voltage distribution programs to meet the security requirements of power distribution. XD Hi-T program includes low-voltage distribution feeder, motor protection, reactive power compensation, lightning protection and grounding and other parts of a comprehensive settlement of the problem of distribution might encounter. At the same time, XD Hi-T provides ABB M series of low voltage power distribution systems to meet the needs of all levels of distribution to terminal distribution level. XD Hi-T overall optimized design of low voltage distribution program through the distribution system design tools DOC, not only rational integration outgoing circuits to reduce investment costs, but also can be calculated by simulating the temperature, on the lower level with the selection calculation to protect and improve the distribution system security, reliability, and fully guarantee personal and property safety of affordable housing.
