UNITECH offers comprehensive field services for transformers, unitized substations (USS), and high-tension (HT) panels, designed to minimize downtime, reduce transport costs, and extend the operational life of your equipment. Our expert engineers bring their extensive experience to a variety of environments, including challenging onshore and offshore installations. Here’s a detailed overview of the field services we provide:

Transformer Refurbishment

• Service Details: Our team can refurbish transformers on-site, restoring them to their original performance levels or enhancing them with modern upgrades. This includes assessing and replacing worn components, updating control systems, and improving overall efficiency.
• Benefits: Refurbishment can extend the lifespan of your transformer, improve reliability, and avoid the higher costs associated with complete replacement.

Radiator Repair or Replacement

• Service Details: We provide on-site repair or replacement of transformer radiators, addressing issues such as leaks, corrosion, or inefficiency. This service ensures that the cooling system operates optimally, preventing overheating and ensuring the transformer functions at peak performance.
• Benefits: Proper radiator maintenance is crucial for the longevity of the transformer, as it helps maintain the correct operating temperature and prevents thermal degradation of the insulation.

Cooler Equipment Replacement

• Service Details: Our field team can replace faulty or outdated cooling equipment, such as fans and pumps, with newer, more efficient models. This service ensures that your transformer’s cooling system meets current performance standards.
• Benefits: Replacing old cooling equipment reduces the risk of overheating, improves energy efficiency, and can lead to significant cost savings in the long term.

Cable Box Replacement

• Service Details: We replace or repair transformer cable boxes that have been damaged or are no longer fit for purpose. This includes ensuring that the new cable box is properly sealed and connected, preventing issues such as moisture ingress and electrical faults.
• Benefits: A secure and properly installed cable box is essential for preventing electrical failures and maintaining the safety and reliability of the transformer.

Oil Replacement or Top-Up

• Service Details: We provide on-site oil replacement or top-up services for transformers, ensuring that the insulating oil is clean, at the correct level, and has the necessary dielectric properties to protect the transformer’s internal components.
• Benefits: Regular oil maintenance prevents insulation breakdown, reduces the risk of electrical faults, and enhances the transformer’s performance and lifespan.

Tapping Switch Modification/Replacement

• Service Details: We can modify or replace tapping switches on-site, adjusting the voltage output of the transformer to match current operational requirements or replacing faulty switches with new ones.
• Benefits: Proper tap switch maintenance ensures stable voltage output, reduces stress on the transformer, and prevents potential operational issues.

Gasket Seal Replacement

• Service Details: Our engineers can replace worn or damaged gasket seals on transformers, preventing oil leaks and ensuring the integrity of the transformer’s oil containment system.
• Benefits: Keeping gasket seals in good condition is critical for preventing oil contamination, maintaining insulation quality, and avoiding costly repairs.

Transformer Relocation

• Service Details: We offer services to safely relocate transformers from one site to another, including disconnection, transportation, reinstallation, and testing. This is particularly useful for companies undergoing site expansions or relocations.
• Benefits: Professional relocation services minimize the risk of damage during transport and ensure the transformer is correctly installed and operational in its new location.

Transformer Up-Rating

• Service Details: We can perform on-site upgrades to increase the power handling capacity of your transformer, allowing it to handle higher loads and meet growing operational demands.
• Benefits: Up-rating can extend the useful life of a transformer, postpone the need for replacement, and accommodate increased power needs without requiring new infrastructure.

HT Switchgear Panel and VCB Panels Service

• Service Details: We service high-tension switchgear and vacuum circuit breaker (VCB) panels on-site, including inspection, repair, and replacement of key components to ensure reliable operation.
• Benefits: Regular maintenance of HT panels and VCBs reduces the risk of electrical failures, enhances safety, and ensures compliance with industry standards.

Transformer Oil Filtration & BDV Improvement

• Service Details: We offer on-site oil filtration services to remove moisture, gases, and particulate matter from transformer oil, improving its dielectric strength (Breakdown Voltage, BDV) and extending the life of the transformer.
• Benefits: Filtration improves the insulating properties of the oil, reduces the risk of electrical faults, and enhances the overall efficiency and reliability of the transformer.

Silica-Gel Breather Replacement

• Service Details: We replace silica-gel breathers on-site to prevent moisture ingress into the transformer, which can compromise the insulating oil and reduce transformer efficiency.
• Benefits: Maintaining effective breathers is essential for preventing moisture-related insulation failure and prolonging the operational life of the transformer.

Painting of the Transformer & HT Panels

• Service Details: We offer on-site painting services for transformers and HT panels, protecting them from corrosion and environmental damage, while also enhancing their appearance.
• Benefits: Proper coating and painting extend the life of the equipment, prevent rust and corrosion, and maintain a professional appearance.

Supply & Fixing of CT - PT Units

• Service Details: We supply and install current transformer (CT) and potential transformer (PT) units on-site, ensuring accurate measurement and protection in electrical systems.
• Benefits: Correct installation and maintenance of CT and PT units are crucial for accurate monitoring, protection, and control in electrical networks, ensuring operational safety and efficiency.

These field services are designed to ensure that your transformers, USS, and HT panels are kept in optimal condition, reducing downtime, improving efficiency, and extending the operational life of your equipment.
