Comprehensive Guide to Mining Transformer Procurement: Features, Pricing, Manufacturers, and Key Considerations

Product Introduction

  Comprehensive Guide to Mining Transformer Procurement: Features, Pricing, Manufacturers, and Key Considerations

  I. Core Features of Mining Transformers

  Explosion-Proof and Protection Ratings:

  Must comply with coal mine safety standards (e.g., MT 944-2005), with enclosure protection ratings of at least IP54 to prevent dust and moisture ingress.

  Some products are MA/KA certified (Coal Mine Safety Certification) to ensure safe underground operation.Adaptability to Harsh Environments:

  Temperature range: -20°C to +50°C, with some models supporting -40°C cold-start capability.

  Seismic resistance: Meets GB/T 2423.10 standards to withstand mining vibrations.Technical Parameter Alignment:

  Rated Capacity: Common specifications include 315KVA, 500KVA, 630KVA, 800KVA, 1000KVA, 1250KVA, 1600KVA, 2000KVA, 2500KVA, 3150KVA, and 4000KVA. Selection should align with mining load requirements.

  Rated Voltage: 6KV/10KV (high-voltage side) and 0.4KV/0.69KV (low-voltage side), with custom voltage options available.

  Connection Group Label: Yy0 or Yd11, tailored to different load characteristics.

  Short-Circuit Impedance: 4%-6% to ensure equipment safety during short circuits.

  II. Market Price Ranges

Price RangeRepresentative Product/ManufacturerKey Price Influencing Factors
Low-End RangeShandong Deli Electric Mining Transformer (~¥80,000/unit)Basic configuration, aluminum core, no smart monitoring features
Mid-RangeHebei Shengzhi/Shandong Tengda Mining Transformers (¥120,000–¥180,000)Copper core, includes temperature control system, MA-certified
High-End RangeJiangsu Anzheng/Liaoning Runsheng Premium Mining Transformers (¥220,000–¥280,000)High explosion-proof rating (ExdI Mb), supports remote monitoring, includes anti-corrosion coating, suitable for deep mine high-temperature environments


  Price Fluctuation Factors:

  Explosion-Proof Rating: ExdI Mb (gas explosion-proof) models cost 15%-20% more than standard types.

  Material Selection: Copper core is 20%-30% more expensive than aluminum but offers lower losses.

  Smart Features: Products with temperature control, telemetry, and telesignaling capabilities are 30%-50% pricier.

  Customization: Special protection ratings (e.g., IP68) and cold-start functions incur additional costs.

  IV. Key Procurement Considerations

  Clarify Requirements:

  Determine short-circuit impedance based on mining load types (e.g., motor starting, lighting).

  Select explosion-proof and protection ratings based on underground conditions (e.g., temperature, humidity, gas concentration).Compare Manufacturers:

  Prioritize manufacturers that support customization and provide MA-certified products.

  Verify manufacturer qualifications (e.g., ISO certification, national mining safety certification).Inquiry and Negotiation:

  Obtain quotes from at least three manufacturers, comparing prices, delivery times, and payment terms.

  Clarify whether taxes, freight, installation/commissioning fees, and explosion-proof certification costs are included.Contract Signing:

  Specify product specifications (e.g., voltage, connection group label), acceptance criteria (e.g., test reports, explosion-proof certification).

  Agree on a warranty period (recommended minimum of 2 years) and after-sales service response time (e.g., 24-hour on-site service).
