Product Features
Unparalleled Production Performance: The frame is treated with a specialized paint layer, ensuring longevity. The internal design boasts features to prevent:
incorrect operation of circuit breakers,
switching of isolators under load,
connecting (closing) grounding wires (grounding switches) while energized,
closing circuit breakers with grounding wires (grounding switches) in place,
accidental entry into live compartments.
Employs advanced BIOSCO technology with a modular structure, simplifying installation and operation.
Constructed from high-strength structural steel, it offers outstanding mechanical strength and a surface treatment that ensures excellent weather resistance.
Sophisticated Environmental Control: Equipped with automatic temperature control devices in both the transformer and low-voltage rooms, ensuring optimal temperature regulation and effective ventilation.
The top insulation layer prevents condensation due to rapid temperature fluctuations, and additional insulation layers can be added around the enclosure for enhanced protection.
Intelligent Operations: Features cutting-edge smart operation and maintenance capabilities with advanced data collection and analysis on both HV & LV switchgear and the transformer.
Design and Customization: Boasts an attractive and customizable design, offering a broad range of choices. Internal structures are available in 'H' and 'T' shapes, with flexible options for corridor and non-corridor layouts.
Enclosure Structure
High Voltage Chamber:
The primary high voltage chamber houses a high-voltage ring main unit. High-voltage switches are equipped with sulfur hexafluoride load switches and vacuum circuit breakers. This chamber ensures the transformer is protected from short circuits, overloads, and other potential risks.
Transformer Chamber:
The three-phase transformer chamber is designed to accommodate both dry-type and liquid (oil) immersed transformers. It features a sophisticated ventilation system with adjustable temperature settings and live space barriers to prevent accidental contact during observation.
Low Voltage Chamber:
The secondary low voltage chamber is available in two assembly forms: with or without a corridor. It can house metering cabinets, main incoming cabinets, outgoing cabinets, capacitor cabinets, and interlocking cabinets (for dual transformers), offering comprehensive functionality for low-voltage switchgear. Capacitive reactive power compensation typically ranges from 15% to 30% of the transformer capacity.
Operating Environment
Ambient Temperature: -25°C to 40°C
Altitude: Not exceeding 1000 meters
Relative Humidity: Not exceeding 90% at 25°C, with short-term peaks up to 100%
Installation Conditions: Suitable for locations devoid of fire, explosion hazards, chemical corrosion, or severe vibrations
