Medium Voltage Prefabricated Substation

• The Medium Voltage Prefabricated Substation serves 10kV/0.4kV distribution projects with rated capacity up to 630kVA.
• It combines medium-voltage control, transformation, and low-voltage distribution in one prefabricated enclosure.
• Typical projects include urban grid construction, overhead-to-underground line conversion, high-rise residential developments, hotels, shopping centers, stations, ports, airports, and parks.
• Confirmed operating conditions are -30°C to +40°C, altitude up to 1000m, and wind speed up to 34m/s, which should be checked against the installation site before selection.

• The high-voltage side may include a three-position load switch, high-voltage current-limiting backup fuse, live-line indicator, cable fault indicator, and 10kV zinc-oxide surge arrester.
• The enclosure uses aluzinc-coated steel sheet and has an IP54 protection level.
• The fully insulated arrangement avoids exposed live parts, which is relevant for residential, commercial, and other densely occupied locations.

• Ring-network, terminal, and dual-power supply modes are available for different distribution architectures.
• Custom work may be based on buyer drawings, capacity, supply mode, high- and low-voltage configuration, and project parameters.
• OEM/ODM cooperation is available after the required authorization arrangements are completed.

• Incoming materials are checked before production, followed by inspections through multiple manufacturing stages and finished-product testing.
• Technical personnel complete 100% electrical performance testing before packing.
• Buyers may arrange third-party on-site inspection, and photos or videos can be provided at key production stages to follow order progress.

• Equipment receives rust-prevention treatment as appropriate and is protected in reinforced export solid-wood cases for long-distance and ocean transportation.
• Standard substation products generally require 10–20 working days; customized orders generally require 20–35 working days according to drawings and technical requirements.
• Complete substation sets start from 1 unit. Before ordering, buyers should confirm capacity, 10kV/0.4kV system conditions, power-supply mode, low-voltage outgoing circuits, reactive compensation requirements, installation environment, quantity, and delivery method.
• EXW and FOB terms are available.
