Single Phase Transformer Pole Mounted

Single Phase Pole Mounted Transformer Certificates

Daelim single phase pole mounted transformer has a series of certificates such as UL/cUL, CSA, and CESI. In addition, many years of market experience in North America and South America in the United States, Canada, Honduras, and other North America.

Single Phase Transformer Details

Single phase pole mounted transformer is a distribution type transformer. Oil-filled single-phase overhead transformers designed and produced by Daelim are normally used for stepping utility distribution voltages (ranging from 2400 to 34500 volis) down to lower uilization volages. Although some are used for stepping down to commercial and industrial voltages such as 277, 240/480, 2400 and 4800, most are used for stepping down to the single-phase voltage of 120/240.

Single Phase Transformer Specifications

Single Phase Transformer Types

There are two types of single-phase transformers, one Conventional Type and the other CSP Type. Ratings range from 5 kVA to 167 kVA.

Conventional Type

The transformer is a cylinder-sealing structure. Each one is fixed with grounding devices, hooks, and supporting lugs that conform to ANSI standards, and or ore two high voltage bushing on the cover, low voltage bushing on the wall of the tank, and eyebolt, connecting terminals. The tap changer should be adjusted based on the instruction after the power is off.

CSP Type

This type of sing-phase transformer can protect itself from thunder and lightning, short circuits, and protect the transiting and distribution line from current failure because of self-malfunction.

Except for some similarities such as cylinder tanks, hooks, lifting lugs, grounding devices, nameplates, core, and winding with the conventional type. This type of sing phase transformer has characteristics and devices as follows:

One or two high voltage bushings are on the cover with a fuse.

One or two arresters are installed on the wall of the tank, whose top end is near the voltage bushing, and connected to the bushing by a copper strip. One secondary breaker switch is above the winding inside the tank, and here are the operating handle, overload reset, and signal light.

All units are built in accordance with IEC60076, ANSI/IEEEC57.12.20, CSA C2.1-06, CSA C2.2-06 and etc.

Single Phase Transformer Test

Each single phase transformer was tested in strict accordance with the latest revision of applicable ANSI^TM, IEEE^TM, CSA, and NEMA with test reports available by serial number of the transformer

Routine tests are:

·Leak test

·Polarity and phase relation

·Resistance

·No-load losses and excitation current

·Load losses and impedance

·Applied voltage

·Induced voltage

·Full wave impulse

·Ratio test

Single Phase Transformer Packaging

There are two packaging methods of single -phase transformers, one is wooden pallet packaging, and the other is wooden frame packaging.

If it is transported by the cabinet, it is usually packed with wooden frames, which are more stable and reliable.

A 40 -foot cabinet, a single-phase transformer with a capacity below 50kva can be equipped with 60 units; 75kva single phase transformer can be equipped with 48 units; 100kva single phase transformer can be equipped with 36 units; 167kva single phase transformer can be equipped with 21 units.
