75 kVA Single Phase Pad Mounted Transformer | DOE 2016, Tamper Proof
Product Overview
Leilang Electric 75 kVA single-phase pad-mounted transformer is a high-security, energy-efficient power distribution solution purpose-built for North American 12.47kV utility grids. Engineered to meet and exceed DOE 2016 mandatory efficiency standards, this unit delivers an industry-leading 99.19% overall efficiency with only 190W no-load loss and 650W load loss, cutting annual energy costs by over 2,000 kWh compared to older non-compliant models.
Equipped with an advanced tamper-proof security system featuring captive penta-head bolts and floating nut design, it effectively prevents unauthorized access, vandalism and copper theft in public and remote locations. Built with 100% high-purity copper windings and a robust Compartmental-Type II dead-front enclosure, it provides maintenance-free operation for over 25 years in extreme outdoor conditions. Fully certified to ANSI/IEEE C57, UL/cUL and CSA standards, it is ideal for medium-to-high density residential communities, commercial centers and public facilities.
DOE 2016 Certified Ultra-High Efficiency - Exceeds DOE 2016 federal energy efficiency requirements by 2-3% with 190W no-load loss and 650W load loss, 15% lower than pre-DOE 2016 models. Saves 2,000-2,500 kWh of electricity annually, qualifying for North American energy rebate programs. Grain-oriented silicon steel core minimizes hysteresis and eddy current losses.
Advanced Tamper-Proof Security System - Captive penta-head security bolts require specialized tools to open, preventing casual tampering. Floating nut design prevents bolt removal even if the head is damaged. Integrated padlock provision for additional layered security with fully welded steel enclosure and tamper-evident seals.
Fully Insulated Zero-Risk Safety Design - Dead-front compartmental construction eliminates all exposed live parts. Multi-layer protection suite includes bayonet fuses, surge arresters and automatic pressure relief valve. NEMA 3R weatherproof enclosure withstands rain, snow, dust and UV radiation.
Low-Maintenance Durable Construction - KNAN self-cooling system with no moving parts eliminates fan maintenance. Fully sealed oil compartment prevents dust and moisture ingress. Electrical grade mineral oil with oxidation inhibitor extends insulation life. All service points are ground-accessible.
Flexible Grid Compatibility - Native 12.47kV primary voltage, the most common distribution voltage in North America. Supports both loop and radial feed distribution networks. 5-position voltage tap changer compensates for line voltage fluctuations with customizable voltage ratings and configurations.
Typical Applications
Medium-to-high density residential neighborhoods and housing developments
Strip malls, convenience stores and small office buildings
Schools, churches, community centers and medical clinics
Parks, street lighting and traffic signal systems
Rural electrification and remote agricultural facilities
Underground utility distribution networks
Frequently Asked Questions
Does this 75 kVA transformer fully comply with DOE 2016 standards?
Yes. Leilang Electric's 75 kVA pad-mounted transformer is DOE 2016 certified, achieving 99.19% overall efficiency with only 190W no-load loss and 650W load loss. It exceeds federal requirements and qualifies for most utility energy rebate programs across North America.
What specific tamper-proof features protect against vandalism and theft?
It features a comprehensive security system including captive penta-head security bolts (requiring specialized tools), a floating nut design that prevents bolt removal, integrated padlock provision, fully welded steel enclosure and tamper-evident seals. This effectively deters copper theft and unauthorized access in public areas.
What other safety certifications does this transformer have?
In addition to DOE 2016 certification, it is UL/cUL listed and fully compliant with ANSI/IEEE C57.12.00, C57.12.28 and CSA standards. All units undergo rigorous third-party testing to meet North American utility-grade safety requirements.
Is this transformer suitable for installation near residential areas?
Absolutely. Its fully insulated dead-front design eliminates electrocution risks, the advanced tamper-proof system prevents vandalism, and it operates at an ultra-quiet ≤51 dBA sound level (quieter than normal conversation), making it ideal for residential neighborhoods.
How often does this transformer need maintenance?
Its fully sealed, self-cooling design requires only annual visual inspections of oil level, enclosure condition and security seals. No routine internal maintenance is needed for the first 10 years of operation, and all service points are easily accessible from ground level.
What is the standard lead time and warranty coverage?
Standard 75 kVA units ship within 15-25 business days. All Leilang Electric transformers come with a 24-month comprehensive warranty from the date of shipment, covering all manufacturing defects. We also provide free lifetime technical support and replacement of easily damaged accessories.
