Product Description

Product Description

Single phase pole mounted transformers designed and produced by Daelim are normally used for stepping utility distribution voltages(from 2400V to 34500V) down to lower utilization voltages. Although some are used for stepping down to commercial and industrial voltages such as 277V, 240/480V, 2400V and 4800V, most are used for stepping down to the single phase voltage of 120/240V.

These transformers also used for small substation, miscellaneous applications and can serve to step up voltages.Daelim designs and produces single phase in two types: single phase pole mounted conventional transformer and completely self protected(CSP) transformer. Power rating up to 167kVA.

Daelim's single-phase fully complies with or even exceeds international standards such as ANSI/IEEE, CSA, and DOE. Single-phase has ul/cul, CSA, IEEE and other certificates. It has been exported to North America, Central and South America and other markets in large quantities.

Conventional Type

 

The transformer is cylinder sealing structure. Each one is fixed with grounding devices, hooks, sup porting lugs which conforms to ANSI standard, and one or 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 basing on the instruction after the power off.

 

CSP Type

This type of transformers are CSP type, which can protect itself from thunder and lighting, short circuit and protect the transiting and distribution line from current failure because of self-malfunction.
Except from some similarities such as cylinder tank, hooks, lifting lugs, grounding devices, nameplates, core and winding with the conventional type. This type of transformers have characteristics and devices as follows:
1) One or two high voltage bushings are on the cover with fuse.
2) One or two arresters are installed on the wall of the tank, whose top end is near to the high 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 operating handle,overload reset and signal light.
3) Low voltage bushing is educed from the wall of the tank, grounding device is fixed to position X2. One end of the single
bushing leads out through the high voltage bushing, the other end is ground connection.
4) All units are built in accordance with ANSI/IEEEC57.12.20, CSA C2.1-06,CSA C2.2-06 and etc.
