Oil Transformer Performance

The oil transformer offers outstanding efficiency and reliability. It provides high-efficiency power conversion, minimizing energy losses. With excellent voltage regulation, it maintains a stable output even under varying load conditions. The internal oil acts as both a coolant and an insulator, effectively dissipating heat and ensuring continuous operation without overheating. It also features high short-circuit withstand capacity, protecting the system from damage.

Processing Technology & Materials

Our manufacturing involves advanced lamination of high-quality silicon steel sheets to reduce eddy current losses. Coils are wound tightly using precision machines and impregnated with special insulating materials. The transformer tank is leak-proof and treated for surface protection. We use high-grade copper or aluminum conductors and specially formulated mineral or synthetic oil with high dielectric properties.

35KV and Below Pad Mounted Transformer

Designed for ground-level installation on concrete pads, these self-contained units enclose the core, windings, and protection devices within a rugged, weather-resistant enclosure. This enhances safety and protects components from environmental factors like rain, snow, and dust.

Frequently Asked Questions

What are the primary applications of pad-mounted transformers?
They are widely used in residential areas to step down voltage for household use, in commercial buildings for HVAC and lighting systems, and in industrial facilities to power heavy machinery.
How does the oil-immersed design benefit the transformer?
The insulating oil serves as an excellent coolant to dissipate heat generated during operation and provides superior dielectric insulation to prevent electrical faults.
What safety features are included in these transformers?
Key protection features include overcurrent protection (fuses/circuit breakers), overvoltage protection (surge arresters), and temperature sensors that trigger alarms or shut downs during overheating.
Can the output voltage be adjusted?
Yes, the units are equipped with tap changers (often OLTC) that allow for voltage regulation to compensate for variations in input voltage, ensuring a stable output.
What environmental protections does the enclosure offer?
The enclosures are typically made of heavy-gauge steel or fiberglass, making them weather-resistant against rain, snow, and dust, while locking mechanisms prevent unauthorized access.
Are these transformers suitable for renewable energy sites?
Absolutely. They are commonly used in wind farms and solar power stations to integrate generated power into the utility grid efficiently.
