Dry-Type Transformer
Medium Voltage Dry Type Transformers
800kVA Dry-Type Transformers
Dry-type transformers are ideal for indoor applications requiring fire resistance and environmental protection. They feature epoxy resin insulation, high reliability, and minimal maintenance.
| Model | Rated Capacity (kVA) | Voltage Level | Cooling Method | Application |
|---|---|---|---|---|
| SCB10 | 100 – 2500 | 6–35kV | AN / AF | Commercial buildings, hospitals, tunnels |
| SCB11 | 100 – 2500 | 10–35kV | AN / AF | Renewable energy, data centers |
| SG Series | 30 – 1600 | ≤10kV | AN | Industrial workshops, marine power |
Key Features: Excellent insulation, low noise, moisture resistance, and long lifespan.
Oil-Immersed Transformer
Three-phase Outdoor 10KV 2.5mva Oil Immersed Converter Distribution Transformer
oil-immersed type transformer
Oil-immersed transformers are suitable for outdoor use and heavy load conditions. The oil acts as insulation and cooling medium, ensuring stable performance and high efficiency.
| Model | Rated Capacity (kVA) | Voltage Ratio | Cooling Method | Application |
|---|---|---|---|---|
| S11 | 30 – 31500 | 6/0.4kV, 10/0.4kV | ONAN | Distribution networks |
| S13 | 100 – 6300 | 10/0.4kV | ONAN / ONAF | Industrial power supply systems |
| SH15 | 100 – 2500 | 10/0.4kV | ONAN | Renewable energy, rural power grid |
Advantages: High efficiency, low loss, quiet operation, optional hermetic sealing.
Phase-Shifting Rectifier Transformer
Used in DC power systems such as electrolysis, steel mills, and drives. Designed to reduce harmonics and improve rectification efficiency.
| Model | Rated Capacity (kVA) | Phase Shift | Voltage Class | Application |
|---|---|---|---|---|
| ZT(P)SFG(H) | 160 – 12000 | 6 / 12 / 24 pulses | Up to 35kV | Electroplating, metallurgy, DC drive systems |
Highlights: Custom vector groups, strong overload capacity, harmonic suppression.
High and Low Voltage Switchgear
Low Voltage Switchgear Manufacturers
ZTelec provides a complete range of HV and LV switchgear cabinets for power distribution, automation, and protection systems.
| Model | Voltage Range | Type | Application |
|---|---|---|---|
| KYN28A-12 | 3.6–12kV | Metal-clad switchgear | Power stations and substations |
| GGD / GCS / MNS | 0.4kV | Low-voltage distribution | Factories, workshops, data centers |
| HXGN15 | 12kV | Ring Main Unit (RMU) | Urban power distribution |
Box-Type Substation (Compact Substation)
Box-type substations integrate transformers, switchgear, and protection devices in one enclosure. Ideal for urban grids, renewable energy, and industrial applications.
| Type | Voltage Level | Capacity (kVA) | Application |
|---|---|---|---|
| YB□-12 | ≤12kV | 100–1600 | Urban residential areas |
