Excellence
Standard Accessories Technical Breakdown
Factory-installed standard components delivering continuous monitoring, protective grounding, and operational reliability.
Rating & Diagram Plate
Anodized SS304/SS316 metallic nameplate offering laser-etched, permanent visibility of electrical ratings, vector group diagram, impedance values, and serial documentation for easy on-site audit and tracing.
Oil Conservator Tank with Drain Plug
High-volume expansion reservoir designed to accommodate oil volume fluctuations across extreme temperature variations. Equipped with heavy-duty drain valves for effortless oil sampling and replacement.
Magnetic & Prismatic Oil Level Indicator
Weatherproof visual oil level gauge with anti-fog glass cover, providing real-time visual inspection of insulating oil levels under intense outdoor solar radiation and harsh ambient conditions.
Thermometer Pocket
Precision-machined brass pocket welded directly into the top tank cover, allowing rapid immersion of temperature sensors and oil temperature indicators (OTI) for calibrated thermal monitoring.
Earthing Terminals
Corrosion-resistant copper-plated or brass grounding terminals providing dual neutral and body earthing points to safely discharge fault currents and prevent electrostatic buildup.
Certified Lifting Plugs & Lugs
Structurally analyzed lifting points designed to sustain total weight during transport, crane hoisting, and site installation in accordance with international rigging safety guidelines.
Air Release Hole with De-aeration Plug
Top-mounted purge valve engineered to release trapped air bubbles during vacuum oil filling, preventing internal partial discharges and ensuring total dielectric insulation saturation.
Rigorous Quality Assurance for Overseas Buyers
At KROS Electric Co., Ltd., we understand that power transformers installed in global utility grids, solar power plants, and industrial complexes demand 100% component integrity. Every standard fitting undergoes rigorous pressure leak tests, surface passivation, and anti-corrosive coating assessments.
