The Layout Form and External Dimensions
Product Functions
◆Integrates high-voltage switchgear, transformer, and low-voltage distribution equipment.
◆Supports multiple high-voltage supply systems: ring-main, terminal, or dual power supply.
◆Accommodates various transformers (e.g., low-loss oil-immersed or dry-type).
◆Provides comprehensive low-voltage solutions: power/lighting distribution, reactive power compensation, metering.
◆Features complete anti-misoperation interlocking for safety.
Applicable Environment
◇Ambient temperature: -10℃ to +40℃.
◇Altitude: ≤1000m.
◇Humidity: Daily average relative humidity ≤95%.
◇Locations free from severe pollution, explosive hazards, chemical corrosion, and intense vibration.
◇Wind speed ≤35m/s; ice covering ≤20mm.
◇Special conditions require consultation with the manufacturer.
Product Highlights
◆Compact & Space-Saving: Occupies only 1/10~1/5 the area of conventional substations.
◆Complete & Reliable: Fully functional compartments with high-performance components.
◆Safe & Interlocked: Comprehensive anti-misoperation features in the high-voltage section.
◆Flexible Configuration: Adaptable to various power supply schemes and transformer types.
◆Durable Enclosure: Corrosion-resistant, insulated color steel plate, offering waterproof and dustproof protection.
◆Smart Ventilation: Natural and forced ventilation with temperature-controlled fans.
◆Easy Maintenance: Equipped with lighting, transformer rails, and accessible design.
Installation Instructions
◇Foundation: Soil bearing capacity >1000Pa. Construct with 200# cement mortar and waterproofing agent. Ensure good drainage and a slight slope toward the oil sump (omit for dry-type transformers).
◇Location: Choose higher, well-drained ground.
◇Grounding: Install main grounding line and electrode per standard methods; grounding resistance must be ≤4 ohms.
◇Compliance: Follow building electrical design codes (e.g., GJ1683). Reference provided dimensional drawings.
