1000kVA 12470V Dry Type Transformer

The 1000kVA 12470V Dry Type Transformer from Guangbian Factory is designed for North American power distribution systems, where 12470V is a standard medium-voltage level. It adopts a three-phase Delta (Δ) connection without a neutral point, ensuring direct compatibility with grid input while simplifying grounding and improving operating stability. This configuration also helps suppress third-harmonic distortion, enhancing overall grid performance and making the transformer widely suitable for substations, industrial plants, and utility distribution networks.

Compared with oil-immersed alternatives, this dry-type design offers:

● Higher fire safety level

● Lower maintenance requirements

● Strong environmental adaptability

● Suitable for indoor and densely populated installations

This makes the 1000kVA 12470V Dry Type Transformer ideal for critical infrastructure such as hospitals, commercial complexes, and industrial plants.

Technical Advantages

The 1000kVA 12470V Dry Type Transformer is built with advanced manufacturing processes across GUANGBIAN’s specialized workshops, including core processing, winding production, and precision assembly departments.

Key advantages include:

● High-efficiency silicon steel core for reduced no-load loss

● Vacuum pressure impregnated (VPI) insulation system for enhanced durability

● Excellent thermal performance with natural or forced air cooling

● Strong short-circuit resistance and mechanical stability

● Low noise operation suitable for urban environments

These engineering features ensure long-term stability and optimized lifecycle cost performance.
