Dry-Type Transformer
Product Overview
Also called cast resin type transformer, it is a solid-state electrical device without rotating parts. It relies on eco-friendly temperature insulation systems and air cooling (no oil or liquid cooling) to operate, making it suitable for indoor and environmentally sensitive scenarios.
Key Specifications:
Rated capacity: 16kVA–3200kVA (6kV/10kV/20kV/35kV); high-power models 4000kVA–25000kVA (6kV/10kV); small-capacity auxiliary models 25kVA–63kVA.
Voltage classes: 6kV, 10kV, 20kV, 35kV (covers medium-voltage mainstream grades for industrial and distribution use).
Special series: Power station auxiliary transformers; seismic/vibration/mechanical resistance models; transformers with On-Load Tap Changer (OLTC); SCB13 series (10kV epoxy-resin insulation) and SG10 type (H-class insulation) as core product lines.
Core parameters: Vector groups Dyn11/Yyn0; short-circuit impedance 4.0%/6.0%/8.0%; tapping ranges ±5% or ±2×2.5%; insulation heat resistance levels B (100℃), F (120℃), H (145℃).
Advantage
Safety & Environmental Friendliness Zero oil usage, self-extinguishing and low fire hazard—no need for fire-resistant vaults or catch basins. No harmful gas emissions, compliant with indoor and eco-sensitive installation requirements.
Low Cost & Easy Maintenance Simple installation (no oil-related auxiliary facilities) reduces upfront costs. Low load losses and no oil replacement needs cut long-term maintenance and operational expenses.
Stable Performance & Durability Adopts high-quality insulation materials (epoxy resin, H-class insulation) and copper windings (for SCB series). Resists seismic, vibration, and mechanical impacts, ensuring reliable operation in harsh industrial environments.
Wide Compatibility Covers small, medium, and high-power demands; supports customization for special scenarios (e.g., power stations, industrial plants) and complies with international standards (CE, UL, ISO, IEC, IEEE, KEMA).
Application
Industrial Sectors: Factories, petrochemical plants, manufacturing facilities, and industrial parks—adapting to harsh working conditions and meeting medium-voltage power distribution needs.
Commercial & Civil Scenarios: Shopping malls, high-rise buildings, residential communities, and data centers—suitable for indoor installation with strict fire and environmental requirements.
Special Facilities: Power stations (as auxiliary transformers), transportation hubs, and infrastructure projects—supporting seismic, vibration-resistant, and continuous operation demands.
Utility Networks: Medium-voltage distribution systems for utility companies, bridging high-voltage transmission and low-voltage user supply.
