Why Choose This Rectifier Transformer?
1. High Efficiency & Low Loss
The ZS series uses grain-oriented silicon steel and oxygen-free copper windings, minimizing no-load and load losses. This reduces operating costs and improves overall system efficiency.
2. Robust Short-Circuit Withstand Capability
Industrial rectifier applications often face fault currents and transient overloads. Our transformer’s reinforced coil structure and rigid core assembly ensure excellent mechanical strength and short-circuit resilience.
3. Low Noise & Low Partial Discharge
Advanced five‑step core lamination reduces magnetostriction noise. Partial discharge is kept below 100 pC, extending insulation life and ensuring safe, quiet operation.
4. No Leakage, Fully Sealed Construction
The corrugated tank is IP55 rated and fully sealed, guaranteeing zero oil leakage throughout the transformer’s service life. High‑quality rubber seals prevent aging and moisture ingress.
5. Strong Overload & Overvoltage Capacity
Capable of continuous operation at 110% overvoltage and full load at 40°C ambient temperature, this transformer is built for harsh industrial environments.
Typical Applications
- Electrolysis (aluminum, copper, zinc production)
- Chemical plants (chlor‑alkali, hydrogen electrolysis)
- Steel & metallurgy (DC arc furnaces, rolling mills)
- DC motor drives and heavy mining equipment
- Battery energy storage and railway traction systems
Quality Assurance
Every ZS-5900KVA/10/0.69KV transformer is factory tested per IEC60076, including no‑load loss, load loss, insulation resistance, temperature rise, and partial discharge measurements. We comply with ISO9001:2015 and offer comprehensive customization (tap changers, cooling options, connection groups, protective devices).
Conclusion
The ZS-5900KVA/10/0.69KV oil-immersed rectifier transformer delivers reliable, efficient, and durable AC‑to‑DC power conversion for heavy industry. Contact us today for a quote or technical consultation.
