Product Advantages of 1250KVA/35KV Oil Immersed Fluid Filled Power Transformer

 

The 1250KVA/35KV Oil Immersed Fluid Filled Power Transformer stands out as an ideal solution for industrial and energy sectors through its cutting-edge innovations. First, the oil filled transformer utilizes high-purity mineral oil for insulation and cooling, achieving 40% higher heat dissipation efficiency than traditional dry-type units, ensuring reliability under 35KV high-voltage conditions. Second, the Oil Immersed Transformer's hermetic structure prevents moisture and contaminants from penetrating, while high-temperature-resistant windings reduce failure rates and enhance grid stability.

Additionally, the modular component design of the oil immersed fluid filled power transformer simplifies installation and maintenance. Certified by international IEC standards for short-circuit resistance, it maintains stable performance even during extreme load fluctuations. Compared to similar products, its lifecycle costs are significantly lower-its insulating oil is recyclable, and core components support rapid replacement, saving users over 30% in maintenance expenses.

Finally, its eco-friendly features are equally notable: the oil filled transformer employs non-toxic, recyclable fluid insulation, while the Oil Immersed Transformer's noise control technology (<55dB) complies with EU industrial zone regulations, making it suitable for deployment in densely populated areas.

FAQ
 

Q1: How to Choose Between Oil-Immersed, Dry-Type, or Amorphous Alloy Transformers Based on Needs?

A:Oil-immersed transformers (e.g., 30-2500 kVA/10 kV Oil-Immersed Three-Phase Dual-Winding):
Applicable scenarios: Large factories, substations, outdoor high-voltage power distribution.
Advantages: Excellent heat dissipation for high loads and high-temperature environments, but requires fire prevention and oil leakage precautions.
Dry-type transformers (e.g., Epoxy resin-cast type, Dry-Type Dual-Winding):
Applicable scenarios: Indoor installations (e.g., data centers, commercial buildings), environments with strict fire safety requirements.
Advantages: No insulation oil, pollution-free, low noise, but requires ventilation for heat dissipation.
Amorphous alloy transformers (e.g., Amorphous Alloy Dry-Type):
Applicable scenarios: Grid-end applications, rural power supply, energy-efficient systems.
Advantages: Reduces no-load loss by over 70%, higher efficiency than traditional transformers, ideal for long-term low-load operations.

Q2: Which Equipment is Suitable for Rectifier Transformers (30-3200 kVA Rectifier Type)?

A: Designed specifically for rectifier equipment, such as:
Electroplating lines, electrolytic cells.
Aluminum/copper electrolysis production.
DC motor drive systems.
Features: Three-phase input, adjustable DC voltage output. Note: Harmonic loads may impact transformer performance.

Q3: What are the Differences Between Prefabricated Substations (European Style) and Combined Transformers (Combined Type)?

A:Prefabricated Substations:
High integration: Includes transformers, low-voltage cabinets, and protection devices pre-installed in weatherproof/fire-resistant enclosures.
Applicable scenarios: Rapidly deployable outdoor power systems (e.g., temporary construction sites, remote areas).
Combined Transformers:
Functional integration: Typically combines transformers, metering devices, and protection equipment to simplify power distribution.
Applicable scenarios: Power distribution hubs for small/medium factories or commercial complexes.

Q4: What is the Voltage Adjustment Method for 30-2500 kVA Dual-Winding Non-Adjustable Voltage Transformers?

A:Non-adjustable type: Fixed output voltage set at factory (e.g., 10 kV input → 400 V output); no on-site adjustment.
Applicable scenarios: Stable voltage environments with minimal load fluctuations (e.g., fixed production lines).
For voltage adjustment, choose on-load tap-changing transformers (customizable).

Q5: What are the Temperature Resistance and Lifespan of Epoxy Resin-Cast Dry-Type Transformers?

A:Temperature resistance: Class F (155°C) or Class H (180°C), with overload capacity up to 1.5× rated power.
Lifespan: Over 20 years under normal operation, but requires regular inspections of winding insulation and cooling systems.
