SCB13 Type Dry‑Type Power Transformer Product Introduction

1. Product Overview

The SCB13 dry-type power transformer is a new-generation cast-resin insulated distribution transformer optimized and upgraded based on traditional dry-type transformer technologies. Different from oil-immersed transformers, this model adopts fully enclosed cast-resin winding structure without insulating oil filling, eliminating hidden dangers of oil leakage, combustion and explosion fundamentally. It is a mainstream environmentally friendly and safe power transmission and distribution equipment in the current power industry.

This series of transformers is mainly designed for 10kV/0.4kV power distribution systems, with a complete capacity range covering conventional engineering application demands. Through optimized core structure and winding process design, it effectively reduces no-load loss and operating noise, and significantly improves operational stability and service life. With outstanding safety, environmental adaptability and low energy consumption performance, it has become the preferred power equipment for indoor, urban and high-safety-level power supply scenarios.

2. Product Technical Parameters

The following are the core technical parameters of SCB13 series dry-type power transformers, covering mainstream capacity models and standard operating indicators, which comply with national and international power industry standards:

3. Product Core Features

3.1 Ultra-low Energy Consumption, Energy-saving and Efficient

The SCB13 series adopts high-quality cold-rolled silicon steel sheets and optimized core lamination process, which greatly reduces no-load loss and no-load current compared with traditional SCB10 and SCB11 models. The overall energy consumption level meets the national first-class energy efficiency standard. Long-term grid operation can effectively reduce power loss and operation cost for users, with obvious energy-saving and emission-reduction benefits.

3.2 High Safety and Strong Environmental Adaptability

The integral cast-resin winding structure has excellent insulation performance and mechanical strength. The equipment is oil-free, non-flammable and non-explosive, and will not produce harmful gas or pollution during operation. It can operate stably in humid, dusty and other harsh indoor environments, and is not affected by extreme weather such as rainwater immersion and high temperature. In addition, the closed structure can effectively prevent small animals from entering and causing short-circuit faults, ensuring safe and continuous power supply.

3.3 Low Noise and Stable Operation

Through core vibration reduction optimization and winding structural damping design, the operation noise of the transformer is effectively controlled below 56dB. The whole machine runs smoothly without obvious vibration and abnormal noise, which will not cause noise interference to the surrounding working and living environment, meeting the noise control requirements of urban built-up areas and public places.

3.4 Compact Structure and Easy Installation

The SCB13 dry-type transformer has a compact overall structure, small floor area and light weight, no need to set up oil pool and fire protection facilities like oil-immersed transformers. It can be directly installed indoors, in cable layers and box-type substations, saving construction space and infrastructure investment for users, with flexible and convenient installation and layout.

3.5 Long Service Life and Strong Durability

The oxygen-free pure copper winding has good electrical conductivity and oxidation resistance, and the cast-resin insulation layer has strong anti-aging and anti-corrosion capabilities. The whole machine has no vulnerable wearing parts, and the structural stability is high. The normal service life can reach more than 30 years under standard operating conditions, with low failure rate and high operational reliability.

4. Application Scenarios

Benefiting from its high safety, environmental protection and low noise advantages, SCB13 dry-type power transformers are widely used in various key fields with high requirements for power supply safety and environmental protection, covering civil, commercial, industrial and new energy industries:

• Urban Civil and Commercial Facilities: High-rise residential buildings, shopping malls, office buildings, hotels and commercial complexes. The oil-free and low-noise features fully meet the indoor power supply safety standards of urban buildings.

• Public Service Institutions: Hospitals, schools, subway stations, airports, municipal public facilities and cultural venues, ensuring stable and safe power supply for public service equipment.

• Industrial Production Sites: Manufacturing factories, industrial parks, mining enterprises and processing workshops, adapting to long-term continuous load operation of industrial power distribution systems.

• New Energy Power Generation: Solar photovoltaic power stations, wind power stations and energy storage power stations, used for step-up and step-down power distribution of new energy power generation systems.

• High-precision Power Supply Scenarios: Data centers, communication base stations and financial power distribution centers, providing high-stability and low-loss power supply for precision electronic equipment and key loads.

• Special Engineering Scenarios: Indoor substations, tunnel engineering, underground power distribution stations and other closed and narrow space power supply occasions.

5. Product Maintenance and After-sales Service

5.1 Daily Maintenance Guidelines

The SCB13 dry-type transformer has extremely low daily maintenance cost due to its oil-free structure. Users only need to carry out simple regular inspection and maintenance to ensure long-term stable operation:

• Regularly clean the dust and sundries on the surface of the transformer winding and shell every 3-6 months to avoid dust accumulation affecting heat dissipation and insulation performance.

• Check the tightness of wiring terminals and connectors regularly to prevent poor contact caused by loose screws and avoid local overheating faults.

• Observe the operating temperature, noise and vibration state of the equipment daily. If there is abnormal temperature rise or strange noise, stop operation for inspection in time.

• For equipment operating in humid environment, regularly check the insulation resistance to ensure the insulation performance meets the standard; avoid long-term overload operation.

• Regularly test the protection devices and temperature control systems to ensure the normal response of over-temperature alarm and trip functions.
