YB-£12/0.4 type High-Voltage/Low-Voltage Prefabricated Substation

Description:

YB-£12/0.4 type High-Voltage/Low-Voltage Prefabricated Substation can realize ring main type and terminal type power supply mode. It’s applicable to urban public power distribution, street lamp electricity, industrial and mining enterprises, etc.. In addition, it meets the Standards GB/T17467 and IEC601330.

Structure features:

u Small size, light weight, beautiful appearance and environmental coordination.

u Composed of a high pressure chamber, a transformer chamber and a low pressure chamber.

u Terminal, ring or dual power supply.

u Single or dual transformer power supply solution.

u Oil-immersed power and Dry power transformer.

u Sufficient natural vents and insulation measures (forced cooling if need).

u Multiple materials or a combination of both help long-term use outdoor.

u Small size when using SF6 load switch cabinet, and suitable for community construction, street lighting engineering renovation.

u Reliable detection of short-circuit and single-phase ground faults because of RTU in the high-voltage ring main cabinet.

u Complete and reliable Five-protection system. Easy to operate and maintain.

Using environment:

u Temperature: Min -45℃~Max+40℃;

u Relative humidity: Daily average ≦95%; Monthly average≦90%;

u Altitude: ≦1000m;

u Shock level: Horizontal acceleration 0.4m/s2,Vertical acceleration 0.15m/s2;

u Installation location: The place with no severe impact, serious pollution and chemical corrosion, no conductive dust and explosion risk.

When the conditions of use exceed the above range, the user shall negotiate with us to determine the allowable range or take corresponding supplementary technical measures.
