YB Series cubicle-type Substation
Summary
The product consists of HV distribution unit, and LV distribution unit and is divided into HV chamber, transformer chamber and LV. The HV chamber has complete functions, it with HXGN-10 ring main unit forms the primary supply system , may be arranged into several supply modes( ring main supply, terminal supply and dual-source supply) and also may be provided with HV metering elements to meet requirements on HV metering . Model S9, S11 and other low loss oil-immersed transformers or dry transformers else may be selected . The transformer chamber is designed to have automatic forced air cooling system and lighting system . The LV chamber can constitute user-required power supply schemes in a panel type or cabinet type structure , provide several functions (Power distribution , lighting distribution reactive power compensation , and metering of electrical power) to meet users' different requirements . And facilitate supply management and improve power supply quality.
