YB25-12/0.4 Prefabricated Substation (American Style), suitable for 10KV ring network power supply, dual power supply or terminal power supply systems, serving as a transformer, metering, compensation control and protection device.

This product complies with the following standards:

GB/T17467-1998 "High Voltage and Low Voltage Prefabricated Substation"

DL/T537-93 "Ordering Technical Conditions for 6-35kV Box-type Substation"

Operating environmental conditions

• Altitude: no more than 1000m;

• Environmental temperature: -35℃ to +40℃; Relative humidity: daily average not exceeding 95%, monthly average not exceeding 90%;

• Installation site: free from fire, explosion hazards, chemical corrosive gases and well-ventilated areas, ground inclination not exceeding 3°

Functions and Features

• Fully insulated, fully sealed, low maintenance, ensuring personal safety:

• Compact structure, with a volume only 1/3 - 1/5 of that of an equivalent European transformer, low height;

• Can adopt a split-box structure to avoid contamination of transformer oil in the tank;

• High-voltage side uses double-fuse full-range protection, significantly reducing costs;

• Can be used in a ring network or as a terminal, with cable heads that can be quickly unplugged at 200A load current; The box body uses honeycomb-type double-layer composite board, with functions of heat insulation and heat dissipation;

• Low-voltage side is equipped with an electronic phase-loss protector, which can quickly disconnect the main incoming switch when abnormal voltage occurs in the system;

• High-voltage side uses oil-immersed load switch or SF6 load switch, which can be electrically upgraded, laying the foundation for distribution network automation;

• Uses oil-cooled S9 or more superior S11 series transformers
