Tengyi recently launched a major supply project of\u00a033kV Distribution Transformers\u00a0for the Kenya Power and Lighting Company (KPLC) grid upgrade. In collaboration with a prominent local installation firm,\u00a0we are committed to supplying a total of 1,600+ high-performance distribution transformers. Accordingly, the first batch of 135 units has successfully passed factory inspections and is now in transit.\u00a0These units were specifically engineered to withstand Kenya\u2019s challenging climate and meet KPLC\u2019s stringent technical benchmarks.<\/p>\n\n\n\n

Technical Solutions: Optimized for 33kV High-Voltage Grids<\/h3>\n\n\n\n

To address the regional 33kV distribution requirements, we provided a versatile portfolio of 25kVA and 50kVA units. The 50kVA series, specifically engineered for this project, features the following specifications:<\/p>\n\n\n

\n\n
    \n
  • Superior Insulation Safety:<\/strong>\u00a0With a primary voltage of 33kV, these units feature a\u00a0170kV Lightning Impulse Level (BIL)<\/strong>\u00a0and 70kV Power Frequency Withstand. This reinforced insulation ensures long-term grid stability in high-altitude and lightning-prone regions across Africa.<\/li>\n\n\n\n
  • Premium Material Options:<\/strong>\u00a0Based on the specific technical requirements of different project segments, we provided both high-performance copper winding<\/strong> and cost-effective aluminum winding<\/strong> options.\u00a0The copper units offer superior thermal stability and lower operational losses (No-load loss as low as 160W).<\/li>\n\n\n\n
  • Standards & Accessories:<\/strong>\u00a0Fully compliant with the\u00a0IEC 60076<\/strong>\u00a0series. Utilizing the\u00a0\u062f\u0627\u064a\u0646 11<\/strong>\u00a0vector group to suppress harmonics, the transformers are equipped with utility-standard accessories, including Oil Temperature Indicators (OTI), pressure relief devices, and conservator tanks.<\/li>\n<\/ul>\n\n<\/div>\n\n\n

    Mass-Scale Supply and Reliable Delivery<\/h3>\n\n\n\n

    To manage the total commitment of 1,600+ units effectively, Tengyi has established a robust sequential delivery mechanism. For this initial 135-unit shipment,\u00a0we implemented specialized export protocols to address the challenges of maritime and inland transit:<\/p>\n\n\n

    \n\n
      \n
    • Risk Mitigation:<\/strong>\u00a0Units were sealed in moisture-proof film and enclosed in heavy-duty export crates with professional container anchoring. This prevents\u00a0oxidation from salt air<\/strong>\u00a0and eliminates risks such as\u00a0bushing breakage<\/strong>\u00a0or\u00a0internal core displacement<\/strong>\u00a0caused by rough transit conditions.<\/li>\n\n\n\n
    • Efficient Logistics:<\/strong>\u00a0All packaging materials are ISPM 15 compliant, ensuring seamless customs clearance at the Port of Mombasa and timely arrival at the installation sites.<\/li>\n<\/ul>\n\n<\/div>\n\n

      Summary<\/strong><\/h3>\n\n\n\n

      The successful dispatch of the first 135 units marks the start of our 1,600-transformer rolling supply plan for Kenya.\u00a0This large-scale infrastructure commitment reaffirms Tengyi\u2019s capacity as a premier supplier for\u00a0utility-grade, high-voltage projects.\u00a0Ultimately,\u00a0this partnership provides the sustained “Technical Certainty” needed for the successful modernization of Kenya\u2019s power grid.<\/p>\n\n\n\n
