Introduction Recently, Haocheng Electric Chairman Zhong Quanxian led the overseas sales team on a market visit to Ethiopia to gain a deeper understanding of local industrial development and electrical infrastructure projects. During the visit, the team toured large-scale industrial parks and supporting power facilities, with particular attention given to an industrial substation project designed to […]

Introduction As utility-scale photovoltaic (PV) projects continue to expand worldwide, the design of reliable and efficient electrical infrastructure has become increasingly important. A utility-scale solar substation is responsible for voltage transformation, medium-voltage power collection, system protection, and grid interconnection within large solar power plants. In modern PV projects, inverter output voltage is typically limited to

Conservator Type vs Hermetically Sealed Transformer: Why This Comparison Matters When selecting an oil immersed transformer, one of the most critical design choices is conservator type vs hermetically sealed transformer. This decision becomes especially important for 2000kVA 35kV applications, where: Oil volume is large Thermal expansion is significant Internal pressure must be carefully controlled Understanding

24kV RMU for Vietnam Distribution Networks: Technical Selection Guide Vietnam’s medium-voltage distribution infrastructure continues to expand alongside rapid industrialization, renewable energy development, and urban grid upgrades. In many utility and industrial projects, 22kV systems are the dominant distribution voltage, while equipment insulation class is commonly rated at 24kV according to IEC standards. Because of their

Cable Branch Box vs RMU: Applications and Selection Guide In modern medium voltage distribution systems, choosing the right equipment is essential for balancing cost, reliability, and operational flexibility. Among the most commonly compared solutions are cable branch box vs RMU (Ring Main Unit). While both are used in cable-based distribution networks, their functions and application

Withdrawable vs Fixed Switchgear: A Practical Technical Comparison The comparison of withdrawable vs fixed switchgear is a key consideration in modern low voltage distribution projects. In low voltage distribution systems, choosing between different switchgear designs has a direct impact on reliability, safety, and long-term maintenance. Among the most common options, the comparison of withdrawable vs

E-House for AI Data Center Power Reliability Solutions The rapid expansion of artificial intelligence, cloud computing, and hyperscale infrastructure is reshaping the requirements of modern electrical systems. Compared with conventional facilities, AI data centers require significantly higher power density, stronger electrical reliability, and faster infrastructure deployment. As GPU clusters, high-performance computing systems, and advanced cooling

Why Solar Power Plants Need PV Step-Up Substations Solar power plants generate electricity through photovoltaic modules and inverters, but the electricity produced is typically at low voltage levels (400V–800V). This voltage is not suitable for direct transmission to medium-voltage distribution networks or utility grids. Without proper voltage conversion, power transmission losses increase, system stability decreases,

Pad Mounted Transformer Types: How to Choose Loop Feed vs Radial Feed Selecting the right pad mounted transformer is essential for ensuring a reliable and cost-effective power distribution system. Among different pad mounted transformer types, the two most widely used configurations are the loop feed transformer and the radial feed transformer. Each configuration is designed
