Core Product Advantages

1.Premium Baosteel Silicon Steel Sheet, Low Loss & Silent Operation

The transformer core adopts high-quality Baosteel silicon steel sheets as the core raw material. With excellent magnetic conductivity and low magnetostriction characteristics, the material effectively reduces no-load loss and electromagnetic loss during equipment operation. It greatly lowers operational vibration and running noise, realizing energy-saving, low-consumption and silent stable operation, and effectively reduces long-term operational energy costs for users.

2.99% High Automatic Production, Efficient & Stable Capacity

The core production process of the transformer realizes 99% high-level automated intelligent manufacturing. The highly standardized and automated production line eliminates errors caused by manual operation, ensuring consistent product quality and precise structural parameters. With a daily production capacity of 50 units, we can efficiently respond to bulk order demands, greatly shorten product delivery cycles and provide stable and sufficient supply support for engineering projects.

3.PCB-Free New Mineral Insulating Oil, Safe & Eco-Friendly

The equipment is filled with brand-new pure mineral insulating oil that contains no PCB (polychlorinated biphenyl) substances. This high-purity insulating oil features excellent insulation performance, arc extinction performance and thermal stability. It is non-toxic, environmentally friendly and pollution-free, meeting global environmental protection standards. While ensuring the safe and stable heat dissipation and insulation of the transformer, it avoids environmental pollution risks and supports green power system operation.

4.CNAS Certified Laboratory, Strict Multi-Item Testing

We own a professional CNAS accredited laboratory with authoritative testing qualifications. Every finished transformer will pass more than ten rigorous professional performance tests before leaving the factory, including insulation performance test, load operation test, pressure resistance test and environmental adaptation test. Layer-by-layer strict quality inspection eliminates defective products, fully guarantees the operational stability, safety and durability of each piece of equipment.

5.Grooved Porcelain Bushing, Solve Traditional Oil Leakage Pain Points

Aiming at the common oil leakage problem of traditional transformers, this product adopts upgraded grooved porcelain bottle (porcelain bushing) structure. The optimized grooved sealing design effectively enhances the fitting tightness and sealing performance of the connecting parts, thoroughly solves the long-standing oil leakage defect of traditional transformers, reduces later maintenance troubles, and improves the overall sealing stability and service life of the equipment.

6.High-Strength Steel Plate Cabinet, 30-Year Rust-Proof Performance

The transformer box body is made of high-quality thickened steel plates and profiled materials, with solid structural strength and strong impact resistance. After professional anti-rust, anti-corrosion and spray treatment, the shell has excellent weather resistance, adapting to outdoor high temperature, low temperature, rain and humidity and other harsh environments. It achieves 30-year long-term rust-free and anti-corrosion performance, greatly reducing equipment aging damage and later maintenance costs.

HV Power Transformer Substation Application

In an HV power transformer substation, the transformer plays a central role in voltage conversion and power distribution. It connects the transmission network with industrial or regional distribution systems, ensuring that electricity is delivered at the correct voltage level for safe and efficient use.

A 35kv oil immersed power transformer is commonly installed in outdoor substations, industrial substations, renewable energy substations, and utility distribution stations. It can be used to step down high-voltage electricity for factory operation, or step up generated power for grid connection.

In industrial substations, HV power transformers help supply stable power to motors, compressors, pumps, furnaces, production lines, and large electrical equipment. Stable transformer performance directly affects production safety, energy efficiency, and system reliability.

For substation applications, transformer design must consider load capacity, short-circuit strength, cooling performance, oil protection system, environmental temperature, altitude, and protection devices. A reliable supplier can provide suitable transformer solutions according to the substation layout and operating requirements.

Large Custom Power Transformers & Small Custom Power Transformers

Different projects require different transformer designs. Large custom power transformers are usually used in power plants, transmission networks, heavy industrial facilities, and high-capacity substations. They require advanced engineering design, strong insulation coordination, efficient cooling systems, and reliable mechanical strength.

For large-capacity applications, the transformer can be customized with on-load tap changers, advanced monitoring devices, special cooling systems, reinforced tank structures, and low-loss core designs. These features help improve operation stability and power system efficiency.

Small custom power transformers are often used for industrial distribution, factory power supply, equipment matching, compact substations, and special electrical systems. They are usually easier to install and can be designed for limited space, specific voltage output, or special environmental requirements.

Whether the project needs large or small custom power transformers, proper design should consider load characteristics, installation site, voltage level, ambient temperature, cooling method, impedance, safety standards, and maintenance requirements. A qualified supplier can provide technical support to match the transformer with the actual power system.

Oil Immersed Power Transformer Market

The oil immersed power transformer market continues to grow with the expansion of power infrastructure, renewable energy projects, industrial modernization, and grid upgrading. Many countries are increasing investment in stable power distribution systems, creating strong demand for reliable medium-voltage and high-voltage transformers.

Industrial users also require more customized transformer solutions to support automation, high-efficiency equipment, and continuous production. As a result, the demand for custom electrical power transformer products is increasing in factories, substations, energy projects, and infrastructure applications.

In the global market, buyers often focus on product efficiency, technical standards, customization ability, delivery capacity, and after-sales support. Choosing professional 35kv oil immersed power transformer suppliers can help reduce project risk and ensure long-term operating reliability.
