Technical Specifications Overview
Product Range:
Three-Phase Low Voltage Transformers: 3, 6, 9, 15, 30, 45, 75, 112.5, 150, 225, 300, 500, 750 kVA.
Three-Phase Medium Voltage Transformers (Standard Ratings): 30, 45, 75, 112.5, 150, 225, 300, 500, 750, 1,000, 1,500, 2,000, 2,500 kVA.
Single-Phase Transformers are available per project requirements, with detailed Full Load Current (FLC) charts provided for common voltage levels from 120V to 600V.
Core Design & Parameters:
Voltage Levels: Low Voltage side standardized at 0.433kV. Medium Voltage side options of 11kV or 33kV to meet Kuwait grid specifications.
Insulation & Cooling: Full range utilizes mineral oil insulation with ONAN (Oil Natural Air Natural) or ONAF (Oil Natural Air Forced) cooling for high load capability.
Vector Group: Predominantly Dyn11, effectively suppressing harmonics and providing a stable neutral point.
Core Design: Utilizes 0.23mm/0.27mm high-permeability grain-oriented silicon steel for low no-load loss (meeting or exceeding IEC 60076 efficiency standards).

Key Features
1. Full Range Coverage & Modular Design
Offers a complete capacity spectrum from small workshops to large primary substations, supporting the industrial zone's "invest-as-needed, phased deployment" expansion strategy. Standardized design ensures spare parts commonality and ease of maintenance.
2. Extreme Climate Adaptability Design
High-Temperature Reinforcement: Winding insulation systems employ high-temperature class materials (e.g., Nomex® or equivalent), designed for ambient temperatures up to 55°C, ensuring continuous full-load operation during Kuwait's extreme summer heat.
Dust & Corrosion Resistance: Corrugated tanks or radiators feature special anti-corrosion coating (Desert-grade C5-M coating). Fully sealed construction or high-efficiency breathers effectively resist sand abrasion and salt spray corrosion.
Thermal Shock Resistance: Optimized internal oil flow design ensures effective control of hotspot temperature rise during rapid load changes and large diurnal temperature variations.
3. High Efficiency & Low Total Cost of Ownership (TCO)
All transformers comply with or exceed IEC 60076-1 efficiency standards (e.g., Ck, C’k levels), significantly reducing operational core and load losses, translating to substantial electricity cost savings for the owner.
4. Intelligent Monitoring & Safety Protection
Standard fittings include oil temperature indicator, pressure relief device, sudden pressure relay, and Buchholz relay (for 750 kVA and above).
Optional integrated intelligent monitoring unit for real-time remote monitoring of load, temperature, oil level, and critical fault alarms. Supports IoT interface for predictive maintenance.
