Description

Description of 110kv Oil Immersed Power Transformer​

In modern power grids—whether for industrial parks, municipal infrastructure, or large-scale energy transmission—110kv Oil Immersed Power Transformers stand as the backbone of stable electricity supply.
 
Engineered to meet the strictest industry standards, our transformers combine robust performance, cost-effectiveness, and flexibility, making them the top choice for utilities, engineering firms, and project developers worldwide.
 

1. Uncompromised Operational Safety & Reliability

 

Safety is non-negotiable in power systems, and our 110kv Oil Immersed Power Transformer is built to eliminate risks while ensuring long-term dependability. We use high-purity insulating oil with excellent thermal conductivity and dielectric properties, which not only cools the transformer efficiently but also prevents electrical breakdowns.
 
Additionally, the transformer is equipped with advanced protection devices (e.g., pressure relief valves, temperature monitors, and gas relays) that detect anomalies in real time—minimizing downtime and avoiding costly failures. With a design life of over 20 years, this transformer delivers consistent performance even in harsh environments (extreme temperatures, high humidity, or dusty conditions).
 

2. Energy Efficiency That Cuts Network Loss & Lowers Operating Costs

 

For power operators, reducing energy waste and operational expenses is critical—and our 110kv Oil Immersed Power Transformer excels in both. It features a low-loss silicon steel core and optimized copper windings, which minimize no-load and load losses by up to 15% compared to standard transformers.
 
This translates to significant savings on electricity bills: over a 10-year lifespan, a single unit can reduce network loss costs by tens of thousands of dollars. Moreover, the transformer’s efficient heat dissipation system reduces the need for additional cooling equipment, further slashing maintenance and operational overhead.
 

3. Superior Short-Circuit Strength & Insulation Performance

 

Power grids often face unexpected short-circuit events, which can damage unqualified transformers. Our 110kv Oil Immersed Power Transformer is designed to withstand extreme electrical stress: its core is reinforced with high-strength clamping structures to resist mechanical deformation during short circuits, while the windings are made of high-grade copper with tight insulation layers (compliant with IEC 60076 standards).
 
The insulating oil is regularly tested for dielectric strength and moisture content, ensuring it maintains optimal insulation performance even after years of use. This rugged design guarantees the transformer remains intact and operational, even in the event of transient voltage spikes or short-circuit faults.
 

4. Compact, Low-Noise & Lightweight Design for Easy Installation

 

Space constraints and noise pollution are common challenges in urban or densely populated areas—and our 110kv Oil Immersed Power Transformer addresses both. Its compact structure reduces the required installation footprint by up to 20% compared to traditional models, making it ideal for substations with limited space.
 
The transformer also features a noise-dampening tank and vibration-isolation pads, keeping operational noise below 55 dB (equivalent to a quiet office)—perfect for installations near residential areas or noise-sensitive facilities. Additionally, its lightweight design (optimized through material selection) simplifies transportation and on-site assembly, cutting down on logistics and labor costs.
 

5. Fully Customized Solutions Tailored to Your Exact Needs

 

Every power project has unique requirements—whether it’s a specific voltage regulation range, special cooling needs (e.g., for high-altitude regions), or custom mounting options (outdoor/indoor, pad-mounted, or pole-mounted). We offer customized 110kv Oil Immersed Power Transformers designed to match your project’s specifications.
 
Our engineering team works closely with you to understand your goals: from adjusting capacity (50MVA to 200MVA) to integrating smart monitoring systems (for remote data tracking) or modifying tank materials for corrosion resistance (e.g., for coastal areas). No matter how specific your needs, we deliver a transformer that fits seamlessly into your power system.
 

6. Competitive Short Delivery Time to Keep Your Project On Track

 

We understand that project delays can be costly—and our streamlined production process ensures fast delivery of your 110kv Oil Immersed Power Transformer.
