Price of Mining Mobile Transformers

　　Price Analysis and Selection Guide for Mine-Mounted Mobile Transformers

　　1. Price Range and Typical Models

　　The price of mine-mounted mobile transformers varies significantly due to factors such as rated capacity, voltage class, explosion-proof configuration, and brand. Below are the mainstream models and their price ranges:

　Note: Some manufacturers in Jining, Shandong, offer low-cost models (e.g., KBSGZY-250/10 for ¥5,600), but the integrity of explosion-proof certification and configuration must be verified.

　　2. Factors Influencing Price

　　Rated Capacity

　　Price is positively correlated with capacity. For example, the KBSGZY-1600KVA model costs more than three times that of the KBSGZY-630KVA model due to increased material usage and process complexity.

　　Voltage Class and Configuration

　　The high-voltage side voltage (10KV/6KV) and low-voltage side output combinations (e.g., 400V/693V) affect design costs.

　　Special configurations (e.g., multiple windings, high-voltage integrated protection devices) significantly increase prices.

　　Explosion-Proof and Safety Certifications

　　Coal Mine Safety Certification (MA) and explosion-proof ratings (e.g., ExdI Mb) are mandatory for mining equipment. Models with these certifications are priced 10%-20% higher.

　　Brand and Origin

　　Yancheng Manufacturers (e.g., Weida, Yuntao): Mass production, moderate pricing, and a full range of capacity models.

　　Shandong Manufacturers: Offer some low-cost options, but the explosion-proof performance and after-sales service must be carefully verified.Market Supply-Demand and Competition

　　The industry is highly competitive, with some manufacturers reducing costs through optimized processes (e.g., aerospace aluminum welding). However, caution is advised regarding the quality risks of low-cost products.

　　3. Selection Recommendations

　　Capacity Matching Principle

　　Select capacity based on load requirements, reserving 20% redundancy. For example, a 630KVA device can support approximately 500KW of load to avoid long-term overload operation.

　　Certification Priority

　　Prioritize models with MA certification to ensure compliance with mine safety regulations and reduce compliance risks.

　　Brand and After-Sales Guarantee

　　Manufacturers like Yancheng Weida and Yuntao offer complete explosion-proof solutions and localized services, suitable for long-term operational guarantees.

　　For low-cost models from Shandong, strictly verify explosion-proof performance and clarify after-sales responsibility clauses.

　　Special Scenario Configurations

　　High-Temperature/Humid Environments: Choose models with enhanced insulation and heat dissipation designs (e.g., corrugated tanks).

　　Intelligent Requirements: Opt for models with intelligent monitoring systems to enable remote status monitoring and fault warnings.Budget Allocation Strategy

　　For core equipment (e.g., main power supply transformers), prioritize branded models to ensure stability.

　　For auxiliary equipment (e.g., temporary power supplies), cost-effective models can be considered, but usage risks must be controlled.

　　4. Market Trends and Risk Warnings

　　Policy-Driven: Stricter mine safety regulations are driving demand for explosion-proof transformers, with non-certified products facing the risk of elimination.

　　Technological Upgrades: Grade 1 energy-efficient transformers are becoming mainstream, capable of saving 15%-25% in electricity costs over the long term.

　　Procurement Risks: Beware of low-cost, non-certified products, which may lead to safety accidents due to explosion-proof failures. Purchase through formal channels.Summary: The price range for mine-mounted mobile transformers is from ¥5,600 to ¥235,000. Users should make selections based on capacity, certification, brand, and budget. Prioritize mainstream models from Yancheng manufacturers to ensure safety, compliance, and long-term reliability, avoiding potential risks associated with low-cost procurement.
