Voltron produces marine and offshore platform transformers with low voltage (1kV) and medium voltage (10kV). Our transformer products have obtained Product Type Approval from CCS (China Classification Society) and Factory Approval from BV (Bureau Veritas). Voltron can provide product certificates from major classification societies, including CCS, ABS, DNV-GL, BV, LR, RINA, and NK.

In 2001, Voltron signed a strategic cooperation agreement with DuPont, leveraging DuPont’s advanced and mature RAY-LITE transformer core technology. The open-type transformers produced by Voltron have consistently held a leading position in the industry.

In 2010, on the occasion of Voltron ‘s 20th anniversary, the company once again collaborated with DuPont, signing a trademark licensing agreement for the DuPont NOMEX brand. In the future, the DuPont NOMEX insulation system will be applied across the entire product range at Voltron , marking a new beginning in the brand alliance between Voltron and DuPont.

In 2020, Voltron and DuPont signed another strategic cooperation agreement, commemorated with a signing ceremony in Yangzhong Linjiang Industrial Park.

1. Reliability of Insulation Technology

Our research spans from initial two-dimensional electric field simulations, three-dimensional electric field measurements, and impact characteristic measurements to later-stage theoretical analysis and simulated experiments on the main insulation, longitudinal insulation, end insulation, insulation of leads, and coil withstand voltage characteristics of transformers. Through years of verification using various methods, we ensure the reliability of transformer insulation.

2. Calculation of leakage magnetic field and reduction of stray loss

Dedicate specialized efforts to calculating and measuring transformer leakage magnetic fields. The research includes shielding structures for leakage magnetic fields, calculations for transformer dynamics and thermal stability, and improvements in transformer dynamic and thermal stability to guarantee accurate calculations and reduce stray losses, enhancing transformer dynamic stability.

3. Precise Analysis of Coil Temperature Fields

Collaborating with numerous domestic universities, we jointly developed programs for calculating coil temperature fields. These programs calculate loss distribution in coils, including resistive losses, eddy current losses in different directions, circulating losses between parallel conductors, and flow field cooling conditions. This enables the accurate calculation of coil temperature distribution and hotspot temperature rises, allowing us to take measures to control hotspot temperature effectively rises that impact transformer lifespan.

4. Reducing Local Discharge in Transformers

Electric field strengths at various locations have undergone numerical analysis during the design phase and have been strictly controlled. Additionally, compliance with manufacturing quality, the reliability of processing methods, and the reasonableness of operating techniques effectively control local discharges in transformers.
