Description

Single-phase pad-mounted transformers provide dependable underground power distribution for medium and low voltage applications. Ranging from 15kVA to 500kVA with a maximum primary voltage rating of 34.5kV, these compact units come with universal bushing wells, a full selection of fuse protection schemes and ANSI-standard tap changer configurations.

Designed and manufactured to meet or surpass ANSI, NEMA and RUS specifications, this transformer series adopts a rugged shell-form core paired with heavy-duty enclosures for long service life, making it an optimal choice for residential, commercial and municipal distribution projects throughout North America.

Key Features

Enhanced Safety：It features a tamper-resistant enclosure fitted with stainless steel locking hardware to block unauthorized entry. An automatic pressure relief valve safely releases internal pressure during fault conditions. Multiple fuse protection options are available, including bayonet, current-limiting and dual-element fuses for complete short-circuit and overload safeguarding.
Stable & Robust Performance：The shell-form core construction delivers superior short-circuit withstand capacity. Coils are wrapped with adhesive-coated insulation for enhanced dielectric strength and aging resistance. ONAN mineral oil cooling maintains consistent operating temperatures during sustained full-load operation.
Long-Lasting Corrosion-Resistant Build：The enclosure is constructed from powder-coated steel with anti-corrosion finish to withstand harsh outdoor climates. A removable access hood facilitates easy on-site inspection and maintenance. Laser-etched nameplates retain clear markings permanently without fading after years of outdoor exposure.
Customizable & Smart Compatible Layout：Multiple ANSI Type I / Type II high-voltage and low-voltage bushing arrangements are offered to match diverse wiring layouts. Optional SCADA integration supports remote monitoring and smart grid control, compatible with modern municipal intelligent power networks.
