Concrete Transformer Substations (BCTS)

BCTS (Block-Type Concrete Transformer Substation) is a compact transformer substation housed in a reinforced concrete enclosure that provides robust protection against external environmental influences. Like other compact transformer substations, it is designed for the transformation, distribution, and metering of electrical power.

Advantages of Concrete Transformer Substations

• High strength and durability — the reinforced concrete enclosure provides reliable protection against weather, mechanical damage, and fire, ensuring a service life of up to 50 years.
• Aesthetic integration — a modern architectural design allows the substation to blend seamlessly into urban and commercial environments while maintaining visual appeal.
• Vandal resistance — the robust concrete housing offers excellent protection against unauthorized access, vandalism, and theft.
• Thermal insulation and safety — concrete provides effective thermal insulation and a high level of protection for the equipment installed inside the substation.
• Modular design — available in various sizes and configurations, enabling an optimal solution for the specific requirements of each project.

They are widely used to supply power to a broad range of facilities, including industrial enterprises, agricultural sites, residential developments, infrastructure facilities, construction sites, and other commercial and public projects.

Types of Compact Transformer Substations (CTS)

The main types include:

1. Indoor Industrial CTS — designed for the power supply of industrial facilities and installed directly inside production workshops or on the plant premises.

1. Terminal-Type CTS — intended for facilities supplied by a single incoming power line. It is equipped with one cable or overhead incoming feeder.

1. Through-Type CTS — designed for facilities with two incoming power supply lines. It features two cable or overhead incoming feeders, providing backup power and increased reliability of the electrical supply.

By Transformer Type

1. Oil-immersed transformer substations — a traditional and cost-effective solution. They operate with a higher noise level and require periodic maintenance.

1. Dry-type transformer substations — a safer and more environmentally friendly alternative. They produce lower noise levels and require minimal routine maintenance.

By Protection Rating

• Open-type substations — designed for indoor installation.
• Enclosed substations — designed for outdoor installation.

By Power Rating

• Low-capacity — up to 100 kVA.
• Medium-capacity — from 100 to 1,000 kVA.
• High-capacity — above 1,000 kVA.

The BCTS (Block-Type Concrete Transformer Substation) is a complete, factory-assembled solution for providing a stable and reliable electricity supply, delivered ready for installation and commissioning.

Design Features

Concrete transformer substations include the following main components:

• Reinforced concrete enclosure manufactured from high-strength reinforced concrete.
• Power transformer that steps voltage down from 6 (10) kV to 0.4 kV.
• Factory-assembled switchgear for distributing electrical power to consumers.
• Protection systems against overloads, short circuits, earth leakage currents, and other fault conditions.
• Control and monitoring systems to improve the reliability and efficiency of the power supply.
• Ventilation and cooling systems for dissipating heat generated by the transformer and other equipment.
• Fire protection systems to ensure a high level of fire safety.
