Why Industrial Facilities Need Power Factor Correction Panels Industrial facilities rely on a stable and efficient power supply to keep production running smoothly. However, equipment such as motors, pumps, compressors, transformers, and HVAC systems consume reactive power, which can lower the overall power factor of the electrical system. A Power Factor Correction Panel is designed […]

Compact substations play a critical role in modern power distribution networks, and compact substation safety is a key concern in system design and operation. They are widely used in industrial facilities, solar power plants, commercial developments, utility projects, and infrastructure construction because of their compact footprint and fast installation. However, compact substations often operate in

As part of its ongoing international expansion strategy, Haocheng Electric recently conducted a business visit to Angola to gain deeper insights into the Angola electrical distribution market, industrial development trends, and infrastructure investment opportunities. The visit provided valuable information about local power distribution requirements and future demand for electrical equipment across multiple industries. Angola Electrical

How to Prevent Condensation in Outdoor Ring Main Units (RMUs) Outdoor Ring Main Units (RMUs) are widely used in medium-voltage distribution networks, renewable energy projects, industrial facilities, and utility substations. However, prolonged exposure to changing weather conditions can create a common but often overlooked challenge: condensation inside the equipment enclosure. High humidity, rainfall, temperature fluctuations,

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
