100kVA Transformer Mounting Pad 13.2kV Padmounted Transformers 3300ft
Leilang Electric 100 kVA single-phase pad-mounted transformer is a high-efficiency power distribution solution optimized for North American 13.2kV utility grids, engineered to deliver industry-leading deployment speed and operational simplicity. Designed to step down 13200GrdY/7620V primary voltage to standard 120/240V secondary power, this unit arrives 100% factory pre-wired and fully tested, eliminating on-site assembly and commissioning work.
Its integrated design enables ultra-fast deployment—simply place on a standard concrete pad and connect cables, cutting installation time by 80% compared to traditional transformers. Built with a fully sealed Compartmental-Type II structure and 100% copper windings, it requires minimal maintenance over its 25+ year service life. Fully certified to UL/cUL, ANSI/IEEE C57, CSA and DOE 2016 standards, it achieves 99.25% overall efficiency, making it ideal for medium-sized commercial facilities, apartment complexes and industrial auxiliary power systems.

- 100% Factory Pre-Wired & Tested: All internal wiring, protection devices and controls are pre-installed and calibrated at the factory. Undergoes comprehensive performance testing including dielectric, load and temperature rise tests. Arrives ready for immediate cable connection with no on-site assembly required. Laser-engraved wiring diagrams and connection labels for error-free installation.
- Ultra-Fast Deployment: Plug-and-play design: Installs in as little as 4 hours by a 2-person crew. No need for specialized tools or heavy equipment beyond a standard forklift. Eliminates on-site transformer assembly, wiring and testing work. Reduces project timelines from weeks to days, accelerating power delivery to your site.
- Minimal Maintenance Design: Fully sealed oil compartment prevents dust and moisture ingress, eliminating internal cleaning. KNAN self-cooling system with no moving parts, no fan maintenance required. All service points (oil level gauge, drain valve, fuses) are easily accessible from ground level. Only requires annual visual inspections, with no routine internal maintenance for the first 10 years.
- Native 13.2kV North American Grid Compatibility: Standard 13.2kV primary voltage, directly compatible with most North American utility distribution networks. 5-position voltage tap changer compensates for line voltage fluctuations. Supports both loop and radial feed distribution systems. Dead-front primary connections ensure safe operation for utility workers.
- Industry-Leading Safety & Reliability: UL/cUL listed and fully compliant with ANSI/IEEE C57 standards. Multi-layer protection system including bayonet fuses, surge arresters and automatic pressure relief valve. Tamper-proof locking system prevents unauthorized access. Corrosion-resistant steel enclosure with domed top to prevent water retention.
