Paraguay Low-Voltage Complete Equipment Specifications

A low-voltage complete set in Paraguay typically includes 0.69kV switchgear, transformers, control and protection devices, and auxiliary systems, designed for integration with high-voltage networks and compliant with GB/T17467-2020 standards.

Key Components and Configuration

A typical low-voltage complete set of equipment in Paraguay, such as those used in wind power or industrial substations, includes:

• Low-voltage switchgear room: Operates at 0.69kV, often in a cabinet structure, providing control, protection, and distribution for downstream loads. Includes lighting and control power for the substation equipment .
• Booster transformer: Steps up low-voltage energy (0.69kV) to medium voltage (e.g., 35kV) for transmission to high-voltage substations .
• High-voltage switchgear integration: Typically includes a 40.5kV or higher switchgear room with AC load switch-fuse combination devices for transformer protection .
• Auxiliary equipment: Includes busbars, cables, insulation materials, temperature regulation systems, and monitoring devices to ensure safe and reliable operation .

Environmental and Operational Parameters

• Altitude: Suitable for installations up to 1000 meters above sea level .
• Seismic resistance: Horizontal acceleration ≤0.4 m/s², vertical ≤0.2 m/s², with a safety factor of 1.67 .
• Wind speed tolerance: Up to 35 m/s .
• Installation conditions: Sites should have minimal vibration, slopes ≤3°, and be free from conductive dust, corrosive substances, or flammable/explosive materials .
• Material construction: Box bodies are made from high-quality steel, anodized aluminum alloy, or color steel composite panels with anti-corrosion treatment and insulation layers .

Standards and Compliance

• Equipment performance meets GB/T17467-2020 for high-voltage/low-voltage prefabricated substations .
• Components are designed for industrial, commercial, and renewable energy applications, ensuring integration with high-voltage networks and compliance with local and international safety standards .

Applications

• Wind power generation: Steps up turbine-generated 0.69kV to 35kV for transmission to booster stations .
• Industrial and mining operations: Complete low-voltage sets provide reliable power distribution and protection for large-scale facilities .
• Substation integration: Can be part of larger substations, such as the Valenzuela Substation, which integrates multiple voltage levels (66kV, 220kV, 500kV) with protection, measurement, and control systems .

Summary

A Paraguay low-voltage complete set is a prefabricated, integrated system combining low-voltage switchgear, transformers, protection devices, and auxiliary equipment. It is designed for robust operation in harsh environments, compliant with international standards, and suitable for renewable energy, industrial, and substation applications. Proper site selection and adherence to environmental limits are critical for safe and efficient operation .
