YB-12 Series Box-Type Substation Overview The YB-12 series box-type substation is a compact, integrated power distribution solution designed for efficient medium-voltage (MV) to low-voltage (LV) electricity transformation. It combines high-voltage switchgear, distribution transformers, and low-voltage switchgear within a single, weatherproof enclosure, making it suitable for diverse applications such as urban power grids, industrial parks, residential areas, and renewable energy projects. Key Features 1. Modular & Compact Design The YB-12 substation features a modular structure that optimizes space utilization while ensuring easy installation and maintenance. Its compact footprint reduces land requirements, making it ideal for space-constrained environments. 2. High-Voltage Components Equipped with 12kV-rated ring main units (RMUs) or load-break switches, the high-voltage compartment ensures reliable power switching and protection. Insulation materials such as SF6 gas or solid insulation enhance safety and durability. 3. Transformer Options The substation supports oil-immersed or dry-type transformers (e.g., SCB epoxy resin), catering to different load demands and environmental conditions. Transformers comply with IEC standards, offering high efficiency (up to 98%) and low losses. 4. Low-Voltage Distribution The LV compartment includes circuit breakers, meters, and protection devices (e.g., surge arresters, relays) for precise power distribution and fault management. Configurations can be customized for 400V/230V output. 5. Robust Enclosure Constructed from corrosion-resistant steel or aluminum, the enclosure provides IP34 or higher protection against dust, moisture, and vandalism. Optional features include ventilation fans, heating systems, and fire-resistant materials. 6. Safety & Compliance The YB-12 series adheres to international standards (IEC 62271, GB/T 17467) and incorporates grounding systems, mechanical interlocks, and arc-flash prevention mechanisms to ensure operator safety. Applications - Urban Infrastructure: Ideal for decentralized power supply in cities. - Industrial Sites: Supports heavy machinery and continuous operations. - Renewable Integration: Compatible with solar/wind farms for grid connection. - Temporary Power: Deployable for construction sites or emergency backup. Advantages - Energy Efficiency: Minimizes transmission losses through localized transformation. - Quick Deployment: Pre-assembled design reduces on-site installation time. - Low Maintenance: Sealed components and remote monitoring options lower lifecycle costs. In summary, the YB-12 series box-type substation delivers reliability, flexibility, and safety for modern power distribution networks, adapting to both conventional and smart grid requirements.
