Padmount Transformer

Padmount Transformer

Padmounted transformers are connected to underground utility distribution lines at what is called a "service drop", in order to step down the primary voltage on the utility distribution line to the lower secondary voltage which is then supplied to a utility customer. Many padmounted transformers may serve a single large building, or it may serve many residences.

A padmount transformer is a ground-mounted utility distribution transformer, which usually is housed in a locked metal cabinet, situated on a small concrete pad. These distribution transformers are normally located in residential subdivisions. Since all of the live contact points are enclosed in a grounded metal box, this kind of transformer can be situated in residential locations and do not need to be fenced, like transformers in utility substations.

Pad Mount Transformers Benefits
  • Thermally conductive, cast epoxy resin is standard which insulates the coils to provide self-cooling and protection from fire, moisture, or leakage.
  • Special corrosion protection for coils and core clamps, even in 100% relative humidity and other harsh environments.
  • Short-term overload capacities guaranteed with available forced air-cooling options (AF).
  • Self-extinguishing materials prevent arcs from short-circuits, eliminating potentially harmful gasses in high temperature conditions.
  • Cost savings are achievable with our compact, light weight, and low load loss, high efficiency transformers.
Applications Of Padmount Transformer

●Residential areas: Providing power distribution for neighborhoods and housing developments

●Commercial facilities: Supplying power to shopping centers, office buildings, and business parks

●Industrial installations: Meeting the power requirements of factories, warehouses, and manufacturing plants

●Utility companies: Supporting efficient power distribution in substations and utility networks
