SCB12 10 kV Class Three-Phase All-Copper Dry-Type Transformer Product Introduction

1. Product Overview

The SCB12 10kV three-phase all-copper dry-type transformer is a high-performance epoxy resin cast dry-type power distribution transformer developed complying with IEC international standards and national industrial specifications. Different from traditional oil-immersed transformers, this product adopts fully sealed vacuum casting process without any insulating oil inside, eliminating hidden dangers of oil leakage, combustion and explosion fundamentally. Equipped with 100% pure copper windings instead of aluminum or mixed materials, it delivers more stable electrical conductivity, stronger overload resistance and longer service life compared with ordinary dry-type transformers.

This series transformer is designed for 10kV medium-voltage power distribution systems, featuring low energy consumption, low noise, safe operation and environmental friendliness. It is widely applied for indoor power transformation and voltage regulation in industrial and commercial scenarios, and can adapt to long-term continuous operation in complex indoor environments with high safety and low maintenance requirements. The optimized core and winding structure effectively reduces no-load loss and load loss, reaching the national energy-saving level 12 standard, which helps users reduce long-term power operation costs.

2. Core Product Parameters

The SCB12 10kV all-copper dry-type transformer covers a complete capacity range to meet different power distribution demands. The core technical parameters are listed in the table below:

3. Product Core Features

3.1 Superior Electrical Performance

Adopting 100% pure copper winding with high conductivity and low resistivity, the transformer ensures more sufficient current transmission and lower heat generation compared with aluminum winding products. The core adopts high-quality silicon steel sheet with step-lap splicing technology, which greatly reduces no-load loss, no-load current and magnetic leakage. The overall electrical performance fully complies with international energy-saving standards, realizing low energy consumption and high efficiency during long-term operation. Meanwhile, the product has strong short-circuit resistance and stable voltage regulation, which can effectively resist instantaneous voltage fluctuation and short-circuit impact in the power grid.

3.2 High Safety & Environmental Protection

Oil-free design completely avoids oil leakage pollution and fire hazards. The F-grade epoxy resin casting material has excellent flame retardant and self-extinguishing performance, no toxic gas emission even under high temperature or arcing conditions. The closed casting structure prevents dust, moisture and foreign matter from entering the coil, effectively avoiding insulation aging and breakdown caused by external environment interference. With ultra-low partial discharge value, it will not cause electromagnetic interference to surrounding electrical equipment, meeting environmental protection and safety requirements of indoor dense scenarios.

3.3 Stable & Durable Operation

The integrated vacuum casting process makes the coil and epoxy resin tightly combined as a whole, with high mechanical strength, anti-vibration and anti-crack performance. Equipped with professional vibration damping devices, the product operates smoothly with extremely low noise, no obvious vibration during full-load operation. The all-copper winding has better oxidation resistance and fatigue resistance, which can maintain stable electrical performance for a long time without frequent failure. Under forced air cooling condition, it can withstand 125% overload operation for a short time, ensuring power supply stability in peak power consumption period.

3.4 Intelligent & Easy Installation

Matching intelligent temperature controller and temperature sensor are equipped as standard, which can real-time monitor the operating temperature of the coil, and support over-temperature alarm and automatic fan start-stop functions. The reserved RS485 communication interface can connect with the remote power monitoring system to realize unattended operation. The whole machine has compact structure, small floor space, no need for oil pool and fire-proof facilities, and supports indoor direct installation, saving construction and installation costs for users.

4. Application Scenarios

5. Product Maintenance & After-Sales Service

5.1 Daily Maintenance Guidelines

This dry-type transformer has low daily maintenance cost due to oil-free design. Users only need to carry out regular simple inspection and maintenance to ensure long-term stable operation. Firstly, regularly clean the dust and sundries on the surface of the transformer and ventilation holes to keep smooth heat dissipation and avoid local overheating. Secondly, check the connection terminals regularly to ensure firm wiring and no loose or oxidation phenomenon, so as to prevent poor contact heating. Thirdly, observe the real-time temperature data of the intelligent temperature controller regularly, check whether the cooling fan works normally, and eliminate hidden dangers of poor heat dissipation in time. In addition, regular insulation resistance detection is recommended for equipment operating for more than one year to ensure qualified insulation performance.

In daily operation, avoid long-term overload operation beyond the equipment rated parameters, and prevent strong vibration and impact on the equipment body. For humid environment scenarios, regular dehumidification treatment should be done in the power distribution room to avoid moisture absorption of coil insulation layer.
