Three Phase Customizable 35KV Level Dry Type Distribution Transformer

Three Phase Customizable 35KV Level Dry-type Distribution Transformer

Product Overview

The Three Phase Customizable 35KV Level Dry-type Distribution Transformer is an advanced epoxy resin cast dry-type power transformer engineered for medium-voltage distribution networks. Utilizing state-of-the-art vacuum casting technology with high-grade epoxy resin, this transformer delivers exceptional electrical performance, operational reliability, and environmental safety. The dry-type design eliminates the need for oil or other hazardous liquids, making it an environmentally friendly and fire-safe solution for modern power distribution systems.

Designed for three-phase, 50/60Hz power systems, this transformer is available in capacities ranging from 30 kVA up to 25,000 kVA, with primary voltages up to 35kV. It serves as an ideal solution for stepping down 35kV grid power to lower distribution voltages (0.4kV, 10kV, or custom voltages) for industrial, commercial, and infrastructure applications.

Whether you require standard configurations or fully customized solutions—including multi-tap designs, dual-voltage outputs, or multi-winding arrangements—our engineering team can tailor the transformer to meet your specific grid requirements and application needs.

Application Fields

The Three Phase Customizable 35KV Level Dry-type Distribution Transformer is widely deployed across diverse industries and infrastructure projects where safety, reliability, and environmental compatibility are paramount.

🏢 Commercial & High-rise Buildings

Ideal for high-rise buildings, commercial centers, shopping malls, office towers, and communication buildings where fire safety regulations prohibit oil-filled equipment. The compact design allows installation directly in building basements or electrical rooms close to load centers.

🏥 Public & Critical Facilities

Widely used in hospitals, schools, theaters, hotels, museums, and other public facilities requiring uninterrupted, safe power supply with minimal fire risk.

🚇 Transportation Infrastructure

Extensively deployed in subway systems, light rail, tunnels, bridges, airports, stations, terminals, and ports. The transformer's moisture resistance and maintenance-free operation make it particularly suitable for underground and tunnel environments.

🏭 Industrial & Petrochemical

Serves heavy industries including metallurgy, chemical plants, pulp and paper mills, mining operations, and petrochemical facilities (oil exploration, refining, natural gas extraction). The corrosion-resistant epoxy encapsulation protects against harsh industrial atmospheres.

⚡ Power Generation & Energy

Applied in thermal power, hydropower, nuclear power, gas power generation, and wind power facilities. Also suitable for photovoltaic solar farms and energy storage systems. The transformer can be installed inside wind turbine nacelles or towers for step-up applications.

🏗️ Urban Infrastructure & Grid

Essential component in urban power distribution networks, substations, and switchgear assemblies. Can be combined with switchgear to form compact substations for urban and rural grid applications.

🏖️ Special Environments

Excellent performance in high-humidity coastal areas, offshore platforms, and other challenging environments where moisture and salt corrosion are concerns.

FAQ

Q1: What is the difference between dry-type and oil-immersed transformers?

A: Dry-type transformers use epoxy resin as the insulation medium instead of oil. This provides several key advantages: fire safety (no flammable oil), environmental friendliness (no risk of oil leaks), maintenance-free operation, and suitability for indoor installation. Oil-immersed transformers typically offer higher capacity ratings but require regular oil maintenance and have higher fire risks.

Q2: What capacity and voltage ranges are available?

A: Our 35kV dry-type distribution transformers are available in capacities from 30 kVA up to 25,000 kVA. Primary voltage is 35kV (with 38.5kV and 36.75kV options), and secondary voltage can be customized to 0.4kV, 10kV, 0.69kV, or other voltages based on your requirements. Custom multi-tap and multi-winding designs are also available.

Q3: What standards do these transformers comply with?

A: Our transformers comply with GB/T 10228-2023, GB/T 1094.11-2022, GB 20052-2024, IEC 60076, and DIN 42523. International certifications such as UL, CE, and ASTA are also available.
