    • Porcelain Bushings: Durable and resistant to high voltages.
    • Composite Insulators: Lightweight and resistant to environmental factors.
    • Epoxy Resin Bushings: For applications requiring high insulation resistance.

• Radiators

  • Details: Radiators are essential for dissipating heat from transformers to prevent overheating. Our inventory includes:
    • Oil Radiators: Designed to handle varying cooling requirements, including standard and high-efficiency models.
    • Fin Type Radiators: For enhanced heat dissipation in compact transformer designs.
    • Customized Radiators: Tailored to specific transformer sizes and cooling needs.

• Gaskets

  • Details: Gaskets ensure that the transformer’s oil and gas systems remain sealed, preventing leaks and contamination. We offer:
    • Silicone Gaskets: Resistant to high temperatures and chemicals.
    • Rubber Gaskets: Suitable for standard sealing applications.
    • Cork Gaskets: For less demanding environments and applications.

• Tap Switches

  • Details: Tap switches allow for voltage adjustments in transformers to accommodate varying load conditions. Available types include:
    • On-Load Tap Changers (OLTC): For adjusting voltage under load without interrupting service.
    • Off-Load Tap Changers: For voltage adjustments when the transformer is de-energized.

• Buchholz Relays

  • Details: Buchholz relays are safety devices that detect gas accumulation and oil leaks within transformers. They provide early warning of potential internal faults. We provide:
    • Standard Buchholz Relays: For typical transformer configurations.
    • Advanced Buchholz Relays: With additional diagnostic features for enhanced monitoring.

• Valves & Silica Gel Breathers

  • Details: Valves and silica gel breathers are crucial for maintaining proper oil levels and moisture control within transformers. Our selection includes:
    • Pressure Relief Valves: To manage internal pressure and prevent over-pressurization.
    • Fill and Drain Valves: For oil handling during maintenance.
    • Silica Gel Breathable Filters: To remove moisture from the air entering the transformer and protect the insulating oil.

• Load Break Switch (LBS)

  • Details: LBS are used for safe switching operations in high-tension systems. We offer:
    • Indoor LBS: Designed for indoor installations with specific safety features.
    • Outdoor LBS: Weather-resistant models suitable for external environments.

• Relays and HT Panel Accessories

  • Details: Relays and accessories for high-tension panels ensure accurate control and protection. Our range includes:
    • Protection Relays: For detecting and isolating faults.
    • Control Relays: For managing operational parameters.
    • Panel Accessories: Such as indicators, alarms, and control switches.

• Temperature Sensors & Scanners

  • Details: Temperature sensors and scanners monitor the operating temperature of transformers, preventing overheating and ensuring efficient performance. We provide:
    • RTDs (Resistance Temperature Detectors): For precise temperature measurements.
    • Thermocouples: For high-temperature applications.
    • Temperature Scanners: For comprehensive temperature monitoring across multiple points.

• Used Transformers & Spare Transformers

  • Details: We offer a range of used and spare transformers for immediate replacement needs. Each transformer is:
    • Refurbished and Tested: To ensure it meets operational standards.
    • Available in Various Ratings: To match your specific requirements.
    • Provided with Warranty: To ensure reliability and performance.
