What is the 15kVA Threephase Padmounted Transformer?

The 15kVA Three-phase Pad-mounted Transformer is a small and durable electrical equipment mainly used for outdoor power transmission. These transformers are generally placed on the ground and are resistant to tampering with and fully enclosed in weatherproof steel casing suitable for urban, suburban, and industrial settings. They are designed, in particular, for providing substation service of conversion of high voltage from the primary distribution circuits to a lower voltage that is consumable by end-users in homes or businesses. The label 15kVA refers to its ability to supply 15 kilovolt-amperes electric power and serves best in small voltage distribution networks that require moderate electrical energy. The three-phase design is used for transmitting power with ease, and this is because the load is spread out evenly and hence provides power stability in any given circumstance. These transformers contain enclosed, oil-immersed structures for efficient dielectric and thermal protection, increasing product life and minimizing service requirements. The pad-mounted arrangement does not require overhead lines which makes it more safe, more appealing to the eye, and easier to install than overhead systems.

 

Single-phase VS Three-phase Pad-mounted Transformer

Single-phase pad-mounted transformers are built to convert high-voltage electricity into low-voltage power for single-phase systems. It has two windings, a high voltage winding, and a low voltage winding, and is ideal for the distribution of power to small residential areas, rural areas, or used in lighting poles. Such substations are less expensive to construct and possess a comparatively small capacity; however, they cannot withstand significant power surges. Three-phase pad-mounted transformers are built for three-phase AC systems which are most commonly installed in industrial, commercial, and urban areas. These transformers have three coils per phase, each phase having three sections, thus the ability to supply constant and well-balanced energy to high power loads like industry and large business buildings. Three-phase transformers have greater capacity and work more efficiently: the loss in delivering electricity over a long range is thus minimized; they are for this reason a vital tool in the transmission of electricity on a large scale.

 

Application

  1. Small Industrial Workshops

In many cases it is installed at relatively small industrial workshops, which work with light machinery: metalworking tools, woodworking equipment, or small conveyor systems. Stable, three-phase power is required for these workshops so that we don’t overload the system and have consistent equipment performance.

  1. Remote Cell Tower Sites

15kVA three-phase pad-mounted transformers are used by telecommunication companies to power cell tower sites in remote or suburban areas. Powering communication equipment, cooling systems, and such devices, these transformers make sure service never stops.

  1. Small Commercial Plazas

An installed 15kVA three-phase pad-mounted transformer is used to supply power for lighting, HVAC systems, and low-demand equipment in small commercial plazas with only a few shops, restaurants, or offices. That provides speedier electricity distribution to all tenants without letting you have a bigger transformer.

  1. Rural Water Pumping Stations

The power of these transformers is ideal for supplying application that obtains and distributes water in rural areas using three-phase motors. Reliable operation is possible with little maintenance due to their compact design, which makes it easy to install just above the pump, close to the site.

  1. EV Charging Stations

A 15kVA three-phase pad-mounted transformer can supply power to a small number of chargers employed in a couple of smaller electric vehicle (EV) charging stations in rural or suburban areas where the demand level is not too high.

  1. Small Educational Facilities

Used to provide 3 phase stable electricity for basic facility needs such as computer labs, lighting, and small air conditioning systems in small schools or training centers with 15kVA three phase pad mounted transformer.
