10kV Box-Type Substation Overview A 10kV box-type substation is a compact, prefabricated electrical distribution unit designed to step down medium-voltage power (10kV) to low-voltage levels (typically 400V or 230V) for industrial, commercial, or residential applications. It integrates high-voltage switchgear, transformers, low-voltage distribution panels, and control systems into a single, enclosed structure, offering space-saving, cost-effective, and efficient power distribution solutions. Key Components 1. High-Voltage (HV) Compartment: - Equipped with 10kV switchgear, including load-break switches, fuse-switch combinations, or vacuum circuit breakers for protection and isolation. - Features insulated busbars, surge arresters, and metering devices for voltage monitoring and surge protection. 2. Transformer Compartment: - Houses a dry-type or oil-immersed transformer (typically 10kV/400V) with capacities ranging from 100kVA to 2500kVA. - Designed for low noise, high efficiency, and minimal maintenance. 3. Low-Voltage (LV) Compartment: - Includes circuit breakers, contactors, and distribution boards to supply power to end-users. - Equipped with protection relays, energy meters, and automation interfaces for remote monitoring. 4. Enclosure & Safety Features: - Constructed from corrosion-resistant steel or aluminum, with IP54 or higher ingress protection. - Ventilation systems, fire-resistant materials, and emergency exits ensure safety. Advantages - Compact Design: Ideal for urban areas with space constraints. - Quick Installation: Pre-assembled modules reduce on-site work and commissioning time. - Reliability: Robust protection systems minimize downtime. - Scalability: Modular design allows for future expansion. Applications - Industrial parks, commercial buildings, renewable energy projects, and infrastructure developments. This substation type ensures safe, efficient, and flexible power distribution while meeting modern grid requirements.
