Reliable 5kVA Pole Transformer 4.16kV/120V, Low Loss & All-Weather Outdoor Operation
Reliable 5kVA Pole Transformer 4.16kV/120V | Leilang Electric
Low Loss & All-Weather Outdoor Operation
Product Overview
The Leilang Electric 5kVA single-phase pole mounted transformer is engineered for dependable 4.16kV to 120V voltage conversion, delivering consistent power for residential, rural, and light commercial overhead distribution systems. Built with premium low-loss magnetic circuit and winding design, this unit minimizes energy waste while maintaining stable output under fluctuating loads. Featuring a rugged all-weather enclosure, corrosion-resistant tank, and fully sealed oil-immersed structure, it operates reliably in rain, wind, humidity, high temperature, and coastal environments year-round. Combining proven reliability, industry-standard voltage matching, ultra-low operating loss, and outdoor durability, this Leilang 5kVA pole transformer provides a cost-effective, low-maintenance solution for utility grids, street lighting, farms, and remote power supply projects.
Core Structure & Process Advantages
All-Weather Sealed Cylindrical Tank
Constructed with heavy-duty cold-rolled steel and electrostatic anti-corrosion coating, the tank withstands UV, rain, salt spray, and extreme temperatures. Fully sealed vacuum oil filling blocks moisture and dust, preventing insulation aging and ensuring long-term outdoor stability. Integrated cooling fins maintain optimal temperature for continuous operation.
Low-Loss High-Efficiency Core
Adopts high-permeability cold-rolled oriented silicon steel with precision step-lapped lamination to drastically reduce no-load and load losses. This low-loss design boosts energy efficiency, lowers long-term power costs, and complies with global energy-saving standards. Vacuum impregnation enhances mechanical strength and reduces operating noise.
Stable Winding & Insulation System
High-conductivity copper windings ensure low resistance and strong short-circuit withstand capability. Insulation materials undergo vacuum pressure impregnation (VPI) for superior dielectric strength and lightning impulse resistance. High-creepage bushings resist pollution and rain flashover for reliable performance in harsh outdoor conditions.
Quick Pole-Mount Installation
Designed for direct mounting on standard utility poles with universal brackets, enabling fast on-site wiring and commissioning without ground construction. Built-in pressure relief valve, oil level indicator, and safety protection devices support maintenance-free daily operation.
