Xi'an Senbao Electric Engineering Co., Ltd.

Based in China, Xi'an Senbao Electric Engineering Co., Ltd. lists five active products in its catalogue. The company focuses on power regulation and correction equipment, including voltage regulators, static VAR compensators and thyristor‑controlled devices. The listed items are the SVR Automatic Feeder Voltage Regulator, a Static var compensator, a Thyristor‑controlled automatic voltage regulator, the DWK Outdoor High‑voltage Var Compensator and a Step voltage regulating var compensator. These products address voltage stability and reactive power management for medium‑ to high‑voltage distribution networks. No additional product lines are indicated in the supplied data.

The five items fall under the electrical apparatus classification of HS chapter 85, heading 8504, which is commonly used for voltage regulators and reactive power compensators. In the global market, such equipment is subject to IEC standards such as IEC 61850 for communication and IEC 61000 for electromagnetic compatibility. Buyers typically require conformity assessment reports and type‑test certificates for grid‑connection approval. Export of these devices from China often follows the standard INCOTERMS CIF or FOB to destinations in Southeast Asia, the Middle East and Europe. The catalogue does not specify certifications held by the supplier.

The catalogue comprises an SVR Automatic Feeder Voltage Regulator designed for feeder stations, a generic Static VAR compensator, a Thyristor‑controlled automatic voltage regulator, the DWK Outdoor High‑voltage VAR compensator intended for outdoor substations, and a Step voltage regulating VAR compensator. In the power‑electronics industry, voltage regulators are commonly rated from 1 kV to 35 kV and provide regulation accuracy of ±0.5 % to ±1 %. Static VAR compensators typically offer reactive power ratings from 0.5 MVar up to several hundred MVar, with response times measured in milliseconds. Thyristor‑controlled regulators use phase‑angle control to adjust output voltage and are evaluated against IEC 61850‑7‑4 for functional performance. Outdoor units are built to IP65 or higher protection levels to withstand harsh environments.

Standard material specifications include copper windings, silicon‑controlled rectifiers and insulated steel enclosures. Typical testing includes harmonic distortion measurement, voltage regulation curve, and overload capability per IEC 60034. Buyers often request data sheets showing voltage range, power rating, efficiency and thermal characteristics. The product family aligns with the broader market of grid‑support equipment used by utilities and large industrial facilities.
