Key Features of Pole Mounted Transformers
Our pole mounted transformers are designed for overhead distribution where a ground mounted unit is impractical. The round corrugated tank, sealed construction and lightweight frame make the unit suitable for mounting directly onto a distribution pole.
Key Features
- Optimised Core and Coil: Step-lap wound core and carefully matched windings give high efficiency, low no-load loss and low audible noise.
- Low High Low Windings: The winding arrangement improves short circuit withstand strength and heat dissipation.
- Dual Voltage Design: Designs meet the basic insulation level (BIL) and short circuit requirements of the target utility standard.
- Sealed Construction: Multiple cover clamps, self resealing pressure relief valve and a sealed tank prevent water ingress and oil leakage.
- Utility Ready Hardware: Lifting lugs, surge arrester bracket provision and clearly marked low voltage leads simplify pole installation.
