Zhejiang Jiangshan Hengli Electrical Co., Ltd. is one of the leading manufacturers and suppliers of three phase power transformer in China. If you're going to wholesale durable three phase power transformer made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
Zhejiang Hengli Electrical delivered 10 pieces of 4000kVA three phase power transformer to Xinjiang China in 2026. The rated power of the transformer is 4000kVA. It is a Step-down transformer 10KV to 400V, high-voltage input 10kV with ±5% tap adjustment, low-voltage output 0.4 kV, commonly used for industrial plant power distribution.
This 4000kVA three phase power transformer is custom-engineered to meet the demanding power needs of textile factories in Xinjiang, China. Its reinforced sealed tank adapts to Xinjiang's extreme climate: big temperature swings, dry air and heavy dust. The 8% impedance design restricts short-circuit current, protecting textile machinery against sudden power surges. Premium copper windings offer outstanding heat dissipation, minimizing downtime for your textile production. Anti-corrosion outer coating guards against sand and wind erosion, extending equipment service life.It delivers stable, consistent power for spinning, weaving and finishing production lines, supporting long-hour continuous operation.

Key Features
Xinjiang features a typical inland continental desert climate: huge annual & day-night temperature swings, freezing cold winters down to-35℃, hot summers, frequent sandstorms, dry air and partial high-altitude zones. These natural conditions set special requirements for local three-phase power transformers used in textile plants, solar farms and industrial parks.
First, -45# low-pour-point transformer oil is mandatory. Standard 25# oil thickens or freezes under extreme cold, losing cooling and insulation capacity. Grade-45 oil keeps good fluidity at-45 °C, guaranteeing reliable cold startup in frigid winter months.
Second, anti-sand, dust-sealed tank structures prevent sand from clogging radiators or polluting insulators. Reinforced anti-corrosion paint resists wind-sand abrasion.
Third, wide-range tap-changer (such as 10±5%) handles unstable local grid voltage caused by large temperature shifts. Enhanced insulation also offsets low-pressure influence at high altitudes.
These customized transformers are also well-suited for neighboring Central-Asian countries including Kazakhstan, Uzbekistan, Kyrgyzstan and Tajikistan, which share comparable arid steppe, large temperature variation and cold winter conditions. They face identical risks: winter deep freeze, seasonal dust storms and grid fluctuation. When exporting, only minor adjustments on local grid voltage standards are needed, while core climate-resistant designs (-45# oil, dust-proof housing, anti-corrosion coating) can be directly reused for industrial, mining and renewable-energy projects.
Application Scenarios
This three phase power transformer is tailor-made for textile manufacturing plants in Xinjiang. Textile production runs nonstop with many high-power motors and looms, requiring steady power output. It handles harsh outdoor and semi-outdoor plant conditions, resisting sandstorms, wide temperature differences and dust accumulation. Besides textile mills, it also works for mining sites, chemical factories and rural power grids with tough natural environments.
