To find the 30/0.4kv distribution transformers currently on sale and obtain the accurate prices, some key information is required. Because the prices can vary significantly depending on the specifications. Please provide detailed parameters and contact us to obtain the prices.

Key Specifications That Drastically Affect Price

1. Power Rating (kVA): This is THE most critical factor. Common ratings for this voltage class include 100kVA, 160kVA, 250kVA, 315kVA, 400kVA, 500kVA, 630kVA, 800kVA, 1000kVA, 1250kVA, 1600kVA, 2000kVA, 2500kVA. A 100kVA transformer costs a fraction of a 2500kVA one.

2. Cooling Type:

ONAN: Oil-Natural Air-Natural (most common for smaller ratings).

ONAF: Oil-Natural Air-Forced (fans added for higher ratings).

3. Vector Group: Dyn11 is overwhelmingly standard for 30/0.4kV distribution in Europe and many regions, but others like Dyn5 or Yzn11 might be specified. Confirming this is essential.

4. Impedance Voltage (%): Typically between 4% and 6% for distribution transformers. Specific project requirements might dictate this.

5. Indoor/Outdoor Use: Construction (tank design, corrosion protection, bushings) differs.

6. Standards & Certifications: Required standards depend on the country/region (e.g., IEC 60076, IEEE C57.12.xx, national standards). Certifications like ISO 9001 are common for manufacturers.

7. Accessories: Temperature gauges, oil level indicators, pressure relief device, tap changer (manual or automatic - OLTC), protection relays, surge arresters, cable boxes (size/type), etc.

8. Material Quality: Copper vs. Aluminum windings (copper is generally more efficient and durable but more expensive). Core steel quality.

9. Manufacturer & Origin: Prices differ between established global brands (ABB, Siemens, Schneider, Eaton, GE, TBEA, etc.), regional players, and manufacturers from different countries (EU, North America, China, India, Turkey, etc.).

10. Quantity: Buying a single unit vs. a bulk order for a project.

11. Delivery Terms & Location: Ex-Works (factory pickup), FOB (port), CIF (port + insurance + freight to destination port), DDP (delivered to your site). Transporting heavy transformers is expensive.

12. Lead Time: Standard lead times are often 8-16 weeks. Rush orders cost significantly more.

Where to Look for Sale Listings & Prices

1. Manufacturer Websites

2. Industrial Distributors & Electrical Wholesalers:

Global/Regional: Rexel, Sonepar, WESCO, Graybar.

Local: Search for "electrical equipment distributor" + your city/region. They often stock standard sizes or can order.

3. Industrial Marketplaces & Classifieds:

Alibaba.com: Primarily for sourcing from manufacturers (especially in Asia). Crucial: Vet suppliers carefully, request detailed specs and certifications. Prices here are often indicative starting points for new units but can be very competitive for bulk.

Thomasnet (USA): Connects buyers with industrial suppliers.

EUROPAGES: European B2B directory.

Industry-Specific Portals: Search for "electrical equipment marketplace".

Very Rough Price Ranges (NEW, Ex-Works, Indicative Only - Q3 2024)

Small (100-315kVA): €3,000 - €12,000

Medium (400-800kVA): €10,000 - €25,000

Large (1000-1600kVA): €18,000 - €45,000

Very Large (2000-2500kVA+): €35,000 - €80,000+

Important Considerations

Lead Times: Expect 8-16 weeks for new units. Plan accordingly.

Transportation & Installation: Factor in significant costs for rigging, transport, and professional installation/commissioning.

Warranty & Support: Understand the warranty terms and availability of local service support.

Certificates: Ensure the transformer comes with necessary test reports (Routine Tests, Type Tests if applicable) and certificates of conformity.
