Huixing supplies Medium Voltage Surge Arresters designed for 10–35kV power distribution systems, helping protect transformers, switchgear, cable terminations, overhead lines, and substation equipment from damaging transient overvoltages. With a gapless zinc oxide design, these arresters provide rapid surge suppression, reliable outdoor performance, and reduced maintenance requirements for demanding utility and industrial applications.

A high voltage circuit breaker is a critical protection device used to control electrical circuits and interrupt dangerous fault currents in transmission and distribution systems. Huixing provides dead-tank SF₆ gas circuit breakers designed for outdoor substations, covering rated voltages from 40.5kV to 245kV, rated currents from 1600A to 4000A, and short-circuit breaking currents from 25kA to 63kA. This article explains its working principle, technical features, application scenarios, selection criteria, and key performance parameters.

Huixing provides professionally engineered Substation Connector Fittings for power infrastructure projects where secure mechanical connections, stable electrical performance, and long-term corrosion resistance are essential. Designed for equipment interconnection, busbar installation, conductor splicing, and structural assembly, these fittings help power engineers build dependable substation systems for demanding operating environments.

High Voltage Disconnector is a critical component for safe electrical isolation in transmission, distribution, substation, and industrial power systems. Huixing supplies the GW4 Series High Voltage Disconnector with voltage classes from 40.5kV to 252kV, combining visible isolation, robust insulation, corrosion resistance, and flexible installation for demanding outdoor power applications.

A transformer fuse is a compact but critical protection device designed to disconnect a transformer from a power system when abnormal current conditions occur. Properly selected fuses can limit short-circuit energy, reduce thermal and mechanical stress, prevent damage from severe faults, and help maintain the stability of the surrounding distribution network. This article explains how transformer fuses work, where they are used, how to select the right type, and what practical factors engineers should consider when designing a reliable transformer protection system.

Huixing Zhongdian's overseas project team is steadily advancing local power infrastructure development in the Dominican Republic, providing comprehensive product solutions including transformers, gas-insulated switchgear (GIS), and distribution systems, along with on-site technical guidance, leveraging Chinese power equipment technology to support power grid upgrades in Latin America.
