Ultimate solution providing highest efficiency

Power System Maintenance Solutions

Hyosung Heavy Industries offers comprehensive engineering and service solutions. Based on our know-how, we offer everything from power plant engineering, construction and supervision to maintenance, and condition monitoring.

Solution

  • Maintenance and inspection of electricity generation facilities
    If the power equipment is operated for a long time after installation or after thorough inspections, consumable parts and operating parts are deteriorated and adhered. Therefore, periodical inspection should be carried out for operation reliability and prevention of power outages. Hyosung heavy industries Co., Ltd. provides maintenance and diagnostic solutions for electric power facilities based on abundant data and experience of construction.

    Features and Benefits

    Reduced risk of accidents(securing quality same as new replacement)
    • Ensure workplace cleanliness through the use of special dustproof rooms.
    • Replace all parts (spacers, electromagnetic valves, etc.) that affect the lifespan of the unit.
    Improved reliability
    • Parts replacement and inspection through scheduled power outage at certain intervals ensures operation reliability and extends service life.
    Preventive diagnosis without outages
    • Through preventive diagnosis without outages, we perform maintenance predictions, stable power operation, repairs and replacements to the parts to prevent equipment aging.
    Life test
    • We provide precise diagnosis using the know-how of being an electric power equipment manufacturer.
    • Using X-ray, UHF PD, and other advanced equipment, we diagnosis whether there are any internal abnormalities.

  • Remodeling Business
    Power facilities need to be remolded over time to prepare for any accidents or expansion that may occur due to customer load changes. Hyosung Heavy Industries provides a solution to extend the lifespan of power facilities through the structure of power facilities, abundant design experience, skilled SV and quality

    Features and Benefits

    Remodeling
    • Eliminate the faulty elements by improving appearance, operation and function quality by applying the lifespan extension method of long-term electric power facilities.
    • By improving the structure, replacing aged consumables such as external parts, relays, OLTC drive box and LCP, customers can expect the same service life as new products.
    Warranty
    • Guarantees the same 42-month warranty period as the factory receipt retrofit applies.
    • Quality is assured through testing and modification procedures optimized for the field remodeling process.
    Simplify work procedures
    • Reduces working time by ensuring optimal remodeling process (GIS 2CCT : within 15 days, GCB 1CCT : within 5 days)
    Capable of operating various portfolios for total power equipment
    • Minimizes accident risk through application of various solutions (new replacement, in-factory modification, field modification) with the introduction of field remodeling of substation units.
    No compatibility problem with existing facilities in substation
  • Spare parts
    If the power equipment is operated for a long time after installation or after thorough inspections, consumable parts and operating parts are deteriorated and adhered. Therefore, periodical inspection should be carried out for operation reliability and prevention of power outages. Hyosung heavy industries Co., Ltd. provides maintenance and diagnostic solutions for electric power facilities based on abundant data and experience of construction.
