Padmount Transformers

VanTran padmount transformers are available in single and three phase configurations, featuring sealed tank construction with welded covers and a nitrogen blanket. Our padmounts are available in sizes up to 10,000 kVA and 34,500 V (with the option of 46,000 V).

Each padmount comes complete with a fully-enclosed, tamper-proof cabinet with a center partition for separation between high and low voltage compartments. Padmounts include pad-lockable three-point latching doors, with an optional penta-head (REA) bolt, ensuring secure access to the high voltage components. 

 Substation transformers can be designed for an array of configuration options. VanTran offers top or side mounting bushings, such as partial and full-length air terminal chambers and close coupling flanges on all tank quadrants. VanTran can take care of it, no matter your requirements. 

 The VanTran Multi-Tap steps up one single generator output voltage to myriad voltage options, all while covering a wide variety of specifications. The Multi-Tap includes standard fork truck pockets and a protective cage, protecting from inadvertent mishandling with no crane required. 

 Do you need to interconnect networks with different operating voltages? VanTran auto-transformers will cover you, especially in growing residential and rural communities. Our customers choose VanTran’s single phase auto-transformers over the traditional three-phase padmount designs to avoid difficulties in easement, installation costs, network reliability and uptime. 

 Vault, or below-grade, applications require custom fits and unique ambient conditions. VanTran engineers solutions for the most challenging applications, using a customizable variety of materials and paint finishes. Matching existing dimensions of existing installations can often be a challenge. Not for VanTran. 

VanTran has provided retrofit services for our customers for over 50 years. Because of our unique design and construction capabilities, customers across a number of industries trust us to expertly replace a transformer specifically tailored to their application requirements.

You might need retrofit services if:

• Your application is affected by a natural disaster, causing premature failure.
• Your transformer is nearing the end of its life and is losing reliability.
• Your transformer is overloaded due to increased loads or varying currents
• Your transformer fails prematurely due to excessive moisture or leaking.

If you need custom retrofit installation, partner with VanTran. Our team works with your specifications in mind and manufactures a solution that optimizes your application.

Grounding transformers, especially zig-zag windings, have numerous applications. For example, the neutral-ground path for three-wire ungrounded systems during a network fault requires a grounding transformer.

Because renewable sites are often susceptible to ground fault conditions, grounding transformers are necessary. They can also be used for 15-degree phase shifts and in mitigation of third or triplex harmonics (e.g. 180 Hz).

 VanTran’s pole mount designs are used in banked indoor vault operations, as well as light and heavy rail operating at power frequencies other than 60 Hz. Industry-leading electrical rail companies use VanTran as their supplier of choice—our transformers are designed and built to withstand various applications, even the most demanding ones.
