Combined Substation (American-style)
){kind=small}
Working Conditions
●Altitude not exceeding 1000 meters;
●Ambient temperature: -35℃ to +40℃;
●Relative humidity: daily average not exceeding 95%, monthly average not exceeding 90%;
●Installation place: free from fire, explosion hazard, and chemical corrosive gas, with good ventilation; the floor inclination shall not exceed 3°.
Functional Features
●Fully insulated, fully enclosed, with minimal maintenance and reliable personal safety protection.
●Compact structure, with volume only 1/3 to 1/5 of similar European-style products, and low height.
●Can adopt a separate compartment structure to prevent oil pollution inside the transformer tank.
●Dual-fuse protection on the high-voltage side covering the entire voltage range, significantly reducing costs.
●Can be used in both ring networks and terminal applications, and the cable connector allows emergency plugging and unplugging under 200A load current.
●The shell is made of honeycomb double-layer composite board, with both heat insulation and heat dissipation capabilities.
●An electronic phase-loss protector is installed on the low-voltage side, which can quickly trip the main incoming switch when system voltage is abnormal.
●High-voltage oil-immersed load switch or SF6 load switch can be electronically upgraded for distribution network automation.
●Uses oil-immersed S9 or higher-grade S11 series transformers.
