10kV preloaded European box changes


Product Overview: 

      YB-box-type substation, also known as the European box changes, by a combination of high voltage switchgear, low voltage power distribution panel, distribution transformers and enclosure of four parts, as a new power supply and distribution unit, than the traditional civilThe substation has many advantages. Because of its small size, small footprint, compact, easy to move, thus greatly shortening the cycle and covers an area of infrastructure, but also reduce the costs of infrastructure. Meanwhile, the box-type substation site installation is simple, no special duty, in particular, it can be in-depth load centers, improve the quality of supply to reduce power loss, enhance the reliability of the power supply as well as the transformation of the distribution network are important. Box changes to complete the transformation of electrical energy, distribution, transmission, metering, compensation, system control, protection and communication functions. The product conforms to GB17467-1998 high and low voltage prefabricated substation and lEC1330 standard. Applicable voltage 35KV andbelow,themajorcapacity2000KVA and small unmanned substation, widely used in urban industrial substation, 10KV switching station, ring network system, the rural network 35KV substation occasions.
