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.
