Product Details
This product consists of outdoor complete switchgear assemblies for both the 40.5kV and 12kV sides. It is widely applicable in urban areas, towns, factories, oilfields, and large construction sites for the reception, transformation, and distribution of electric power. Key features include a highly integrated design, compact footprint, ease of installation, low cost, a high level of comprehensive automation, and safe, reliable operation.
The product complies with the GB/17467 national standard.
Product Features:
The integrated substation structure comprises two high-voltage switchgear compartments (for the 40.5kV and 12kV sides), a relay protection compartment, and a transformer. The enclosures for the high-voltage switchgear and relay protection compartments can be constructed from stainless steel, carbon steel, or composite panels. Stainless steel structures offer exceptional corrosion resistance and mechanical strength; carbon steel components undergo specialized anti-corrosion treatment; and composite panels provide aesthetic appeal with vibrant colors, as well as thermal insulation and flame-retardant properties.
The 40.5kV high-voltage compartment accommodates switchgear such as the KYN61-40.5 or KYN10-40.5 models, with users free to choose between overhead line or cable connections for the 40.5kV incoming and outgoing circuits.
The 12kV high-voltage compartment accommodates switchgear cabinets such as the XGN2-12, XGN66-12, or KYN28A-12, or ring main units (RMUs) such as the HXGNL5-(FR) or X6N15-12(FR).
The relay protection compartment houses AC panels, DC panels, signal panels, remote control panels (RTU), and carrier communication or fiber-optic terminal panels.
