The document describes two types of transformers: conventional and complete self-protected. The conventional transformer has a cylinder sealing structure with grounding devices, hooks, and high/low voltage bushings. The complete self-protected transformer can protect itself from threats like lightning and short circuits. It has features like arresters and a secondary breaker switch inside the tank. The document also lists specifications for single phase pole mounted distribution transformers ranging from 30 to 2500 kVA.

Conventional Type:
The transformer is cylinder sealing structure. Each one is fixed with grounding devices, hooks, supporting
lugs which conform 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 teminals, High voltage taps should be connected when the power is
cut off.
Complete Self-Protected Type:
This transformer is csp type, which can protect itself from thunder and lightning, 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 transformer has characteristics and devices as follows; One
of two high voltage bushings in which there ls fuse;
One or two arresters, 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 breader switch above the winding inside the tank, and here are operating handle. overload
reset and signal light Low voltage bushing educed from the wall of the tank, grounding device is fixed to position
X2.
Core: C.R.G.O core and amorphous metal core can be chosen.
