Indoor distribution transformers
1. Low loss, and significantly energy-saving.
2. The core laminations are made up from high-quality cold-rolled grain-oriented silicon steel sheets
3. Zigzag directed flow of oil are provided within the windings
4. The regulating winding is a separate winding which apart from the high voltage main winding
5. The windings of one phase are assembled into an integral phase block before placing into the core.
6. Core frames in the form of a flat plate are used for clamping the core.
7.Transformer tanks are fabricated with steel plates wide enough so that there are no weld joints on each surface.
8.Diaphragm membrane is provided within the conservator, preventing direct contact of oil with air, protecting the oil from aging
9.Reliably sealed, and fine machined for sealed surface.
10. Quality assurance rules are also observed for all insulating parts,and main components.
1 .Customized design depends on your requirement. OEM is welcomed.
2 .Reply your inquiry in half of hour,24 hours on line.
3.Special discount and protection of sales area provided to our distributor.
4.Warranty:1year.
There are different ways in which transformers are installed and used as part of a commercial building electrical system. These application types include:
Indoor distribution transformers are used with panelboards and are separately mounted to supply the specific electrical load requirements in a system-specific application within the system distribution. Several transformer types rated higher than 600 V for oil insulated type, higher than 35,000 V for dry type, and other transformers rated higher than 600 V are required to be located in vault rooms, which must be built with fire-rated enclosures depending on the transformer type and applicable local authority requirements, when indoors. Transformers that are not over 600 V and are part of the indoor building electrical system distribution have both primary and secondary voltages below 600 V with the most common voltage level change from 480 V to 208 Y/120 V.
Pad-mounted transformers are installed outside and are considered the first option for supplying service entrance voltage to the building electrical system based on the project size and requirements. They typically have primary voltages higher than 600 V and secondary voltages lower than 600 V with compartments for the associated protective devices assembled in an integral tamper-resistant and weatherproof unit.
In addition, the size of the commercial facility will determine the appropriate approach for designing the electrical distribution system for the specific application. In this electrical system design, the transformer can be used as part of a substation, primary unit substation, secondary unit substation, or network configuration.
