SCB Series Dry-Type Power Transformer Product Introduction

1. Product Overview

The SCB series dry-type power transformer is a mainstream epoxy resin cast dry-type power distribution equipment widely used in medium and low voltage power systems. Adopting advanced vacuum epoxy resin casting and foil winding technology, this series of transformers completely abandons the traditional oil-immersed insulation structure, realizing full oil-free operation. It covers multiple efficiency grades including SCB10, SCB11, SCB12 and SCB13, with stable performance covering 6kV to 35kV voltage levels.

Different from ordinary transformers, the whole machine features solid insulation, compact structure and strong environmental adaptability. The windings are integrally cast with high-purity epoxy resin, which effectively isolates external moisture, dust and corrosive gases. With reliable flame retardant and explosion-proof performance, it can be directly installed in indoor load centers without building special transformer rooms, greatly saving engineering space and construction costs. This series of products strictly complies with IEC international standards and national power industry specifications, and has passed rigorous type tests to ensure stable and long-term operation in various complex power supply environments.

2. Core Product Parameters

The following are the standard core parameters of SCB series dry-type power transformers (conventional 10kV class), covering mainstream models and performance indicators for engineering selection and application reference:

3. Product Core Features

3.1 Excellent Safety Performance

The whole machine adopts oil-free epoxy resin solid insulation structure. The epoxy resin material has natural flame retardant, self-extinguishing and non-combustible characteristics, which will not cause fire, explosion or oil leakage accidents. It avoids the safety hazards of traditional oil-immersed transformers such as oil leakage pollution and fire spread. In case of extreme overload or external short circuit, the winding insulation will not fail suddenly, ensuring the safety of power supply equipment and on-site environment.

3.2 Low Loss and Energy Saving

Adopting high-quality cold-rolled silicon steel sheets and optimized electromagnetic design, combined with precise foil winding process, the no-load loss and load loss of SCB series transformers are significantly reduced compared with traditional products. The upgraded SCB12 and SCB13 high-efficiency models have more outstanding energy-saving effects, which can effectively reduce long-term power operation consumption and create obvious economic benefits for users. Meanwhile, the optimized structural design greatly reduces operating noise, meeting the noise control requirements of urban and indoor environments.

3.3 High Structural Strength and Reliability

The integral vacuum casting process makes the winding and insulation structure integrated, with high mechanical strength and strong resistance to short-circuit impact and vibration. It will not produce winding deformation, loose wiring or insulation aging problems during long-term operation. The product has ultra-low partial discharge, stable thermal performance and strong moisture and corrosion resistance, and can operate normally in high humidity, dusty and other harsh environments without special environmental improvement.

3.4 Low Maintenance and Strong Adaptability

Due to the oil-free fully sealed structure, there is no need to replace insulating oil, clean oil circuits and other routine maintenance work. The equipment is small in size and light in weight, saving installation space and foundation investment. It can be installed indoors, outdoors, in basement substations and other scenarios, with flexible installation methods and strong on-site adaptability.

4. Application Scenarios

Benefiting from outstanding safety, environmental protection and stable performance, SCB series dry-type power transformers are widely used in scenarios with high requirements for power supply safety, environmental protection and space layout, covering civil construction, industrial manufacturing, new energy and public infrastructure fields:

• Urban Civil Construction: High-rise buildings, commercial plazas, office buildings, residential communities, hotels and other indoor power distribution systems, effectively avoiding fire hazards and environmental pollution risks in densely populated areas.

• Public Infrastructure: Airports, railway stations, subway stations, hospitals, schools and key public service places, ensuring continuous and safe power supply for public facilities.

• Industrial Manufacturing: Factory workshops, chemical plants, mining enterprises, processing plants and other industrial sites, adapting to harsh industrial environments and meeting high-load and stable power supply demands of industrial equipment.

• New Energy Industry: Photovoltaic power stations, wind power stations, energy storage power stations and distributed power generation projects, matching the power conversion and distribution needs of new energy systems.

• Special Fire-proof and Explosion-proof Scenarios: Oil depots, gas stations, chemical parks and other flammable and explosive places, as well as underground substations and closed power distribution rooms, meeting strict safety and fire protection standards.

5. Product Maintenance and After-sales Service

5.1 Daily Maintenance Guidelines

SCB series dry-type transformers are basically maintenance-free in daily operation, and only need simple regular inspection and maintenance to ensure long-term stable operation:

• Routine Inspection (Monthly): Check the surface of the transformer winding and shell for dust accumulation, cracks and discoloration; confirm that the wiring terminals are firm without loosening and heating; check whether the cooling fan and temperature control device work normally.

• Quarterly Maintenance: Clean the surface dust of the winding and radiator with dry compressed air to ensure smooth heat dissipation; test the insulation resistance of the whole machine to ensure the insulation performance is within the standard range.

• Annual Comprehensive Inspection: Conduct a comprehensive performance test on the transformer, including loss test, noise test and partial discharge detection; check the aging degree of internal accessories and fasteners, and replace aging parts in time if any.

• Environment Management: Keep the installation environment dry and ventilated, avoid long-term exposure to corrosive gas and heavy dust, and prevent foreign matters from entering the equipment interior.
