Three-Phase Pad-Mounted Distribution Transformer | 75-3000 kVA, Loop/Radial Feed

Dead-front oil-filled padmount, 2.4-34.5 kV class, IEEE C57 / DOE 2016 design

$6800.00

Overview

Three-phase pad-mounted (padmount) distribution transformers are compact, tamper-resistant, liquid-filled units for underground residential and commercial distribution. The dead-front, compartmentalised ANSI-green cabinet keeps HV and LV terminations isolated behind locked doors for safe street-level installation. Units are engineered to North-American practice and are supplied to the customer's voltage, kVA and feed configuration.

Key Features

  • Dead-front construction with separate HV and LV compartments

  • Loop-feed (6 bushings) or radial-feed (3 bushings) arrangements

  • Bay-O-Net / canister fusing and load-break elbow accessories

  • Mineral oil or biodegradable FR3 natural ester on request

  • Copper or aluminium windings; ONAN self-cooled, 65 °C rise

  • NEMA 3R tamper-resistant enclosure, ANSI 70 green powder coat
