China Mobile Substation of American Type Outdoor Combined Substation Compact Pad Mounted Transformer Substation

ZGS Series

Product Overview
This product is specifically designed for 7.2/12kV ring network, dual power supply, and terminal power supply systems, integrating high-voltage power distribution, metering, compensation, and protection functions. The high-voltage side is equipped with multi-position load switches and fuses, while the low-voltage side can be equipped with customized power distribution modules such as control devices, reactive power compensation, and energy metering as needed. The equipment supports indoor and outdoor installation and is widely used in industrial parks, commercial centers, high-rise buildings, and other similar settings.

Model Definition

Features

● Compact Design: Volume is only ~1/3 of domestic European-style substations with the same capacity.

● Fully Sealed & Insulated: Eliminates the need for insulation clearances, ensuring personal safety.

● Flexible Application: Suitable for both ring main and terminal systems with easy conversion, enhancing power supply reliability.

● Load-bearing cable joint: Rated load current can reach 200A. It can not only operate under normal load, but also act as a load switch in emergency conditions, and has a reliable isolating switch function.

● It adopts a delta/star connection + column structure, which features excellent voltage quality, no neutral point offset, low cabinet temperature rise, low noise, and reliable lightning protection performance.

Operating conditions

● Altitude: ≤1000m (special design required for higher altitudes)

● Wind Pressure: ≤10Pa (equivalent to 35m/s)

● Humidity: Daily avg. ≤95%, monthly avg. ≤90%

● Temperature: -25°C to +40°C

● Vibration Resistance: Horizontal acceleration 0.4m/s²; vertical acceleration 0.15m/s²

● Seismic Intensity: 8 degrees

● Installation Inclination: ≤3°

● Environmental Requirements: Free from corrosive/flammable gases, water vapor pollution; no severe vibration at installation site.
