Overseas 35kV to 400V Oil-immersed & Dry-type Transformer Delivery Project

This cross-border overseas project covers power distribution construction for overseas industrial and residential zones. We supplied full series transformers including oil-immersed and dry-type models, covering voltage conversion from 35kV down to 400V. Tailored to local power grid standards and harsh on-site operating conditions, we delivered qualified equipment with reliable performance and complete certification. The case fully reflects our strong manufacturing capacity, diversified product lineup and mature overseas project delivery experience.

Project Background

The overseas client launched regional power infrastructure construction, requiring large quantities of step-down transformers to convert 35kV high voltage into 400V usable low voltage power. The construction site features variable climate, heavy humidity and frequent load changes. Local power management department set strict requirements on equipment safety, heat resistance, anti-corrosion and operation stability. Meanwhile, the project needed mixed use of oil-immersed and dry-type transformers to fit indoor and outdoor installation demands. The client sought a qualified manufacturer capable of supplying full-range transformer products and meeting international inspection standards.

Project Introduction

We undertook mass production and export delivery of supporting transformers for this overseas project. The supplied products include conventional oil-immersed transformers and fire-resistant dry-type transformers, all designed for 35kV to 400V voltage conversion. Products adopt silicon steel and amorphous alloy magnetic cores, applicable to outdoor substation, factory workshop, residential area and commercial power distribution occasions. All items comply with IEC international norms and local power access standards. We finished customized adjustment, strict performance testing, export packaging and scheduled shipment, ensuring smooth installation and stable power supply after equipment arrival.

Corresponding Solution

We matched different transformer types according to actual installation environment. Cost-effective oil-immersed transformers are arranged for outdoor open space installation, featuring strong heat dissipation and long continuous working life. Flame retardant dry-type transformers are applied in indoor dense facilities, with no oil leakage risk and high safety level.

High quality magnetic core materials are adopted to cut no-load loss and lower running noise, adapting to unstable local power load. Anti-rust and moisture-proof structure design enhances environmental adaptability. Full range tests on voltage conversion, insulation resistance and temperature rise are carried out before delivery. We also provided complete export documents, installation manuals and remote technical guidance, guaranteeing the project runs smoothly.

Customer Feedback

"All delivered 35kV to 400V transformers work steadily on site. Both oil-immersed and dry-type products satisfy our diverse installation needs. The quality meets international standards, and the team offers thoughtful overseas technical support. We are pleased with this cooperation and will place repeated orders for follow-up expansion projects."
