Three phase Pad Mounted Distribution Transformer

Three phase Pad Mounted Distribution Transformer Description

Three phase Pad Mounted Distribution Transformer are made in power ratings from around 45kVA to around 6000 kVA and often include built-in fuses and switches. Primary power cables may be connected with elbow connectors, which can be operated when energized using a hot stick and allows for flexibility in repair and maintenance.

The rated power of TRANSpower's three phase pad mounted transformers is 45-6000kva, the voltage up to 35kv, and it is grounded. Transpower pad-mounted transformer design and production can meet various international standards, such as ANSI, IEEE standards, etc. TRANSpower's three phase pad mounted transformer with UL, CSA, IEE certificates.

Frequently Asked Questions (FAQ)

Q: What Is The Difference Between Loop Feed And Radial Feed?

A: Radial feed Transformers will have three high voltage bushings (H1, H2, and H3). There is one bushing for each phase to allow for the incoming high voltage cables. On Wye and Grounded Wye connected Transformers, there will also be an H0 bushing. Loop feed Transformers will have six high voltage bushings (H1A, H2A, H3A, H1B, H2B, and H3B). There are two bushings for each phase. This allows the customer to connect all of their Transformers in a loop configuration. It will also allow the customer to bring two feeds to the Transformer. A four position switch can be used to switch between the A feed and the B feed.

Q: What Is The Difference Between Dead Front And Live Front?

A: Live-front: The voltage-carrying parts are exposed. Live-front terminations have high voltage connectors, arresters, or fuses are exposed to the operator after cabinet has been opened. Dead-front: Often referred to as dead-front bushings. Safety is enhanced as there are no current-carrying parts exposed to the operator. For overhead distribution transformers and underground submersible transformers, live front is common. For pad mount transformers, the primary is typically dead front and the secondary is live front. Protection barriers can be added to live front pad mounted transformers

Q: What Types Of Transformer Liquids Does Transpower Electrical Use?

A: Transpower Electrical offered mineral oil fluid (ONAN) and biodegradable fluid (KNAN). On request we can provide brand name FR3 fluid or other brand name fluids for additional cost and lead time.. All fluids offered by Transpower Electrical are non-PCB containing fluids.
