167 kVA Transformer Overview
167 kVA Pole Mounted Transformer
OMEK Power’s 167 kVA transformer belongs to the D11 series single phase pole mounted transformer. It features a fully sealed cylindrical oil tank, and can be filled in with environmentally friendly FR3 vegetable oil or mineral oil. No PCB, so it meets your environmental protection requirements.
Super flexible installation. This distribution transformer can be placed on a platform or directly hung on a utility pole.
OMEK 167 kVA pole mounted transformers are compliance with ANSI/NEMA/IEEE/CSA/DOE, and they have passed the type test of the authoritative transformer testing center. This 167kVA single-phase overhead transformer is your reliable solution for power distribution networks.
167 kVA Pad Mount Transformer
OMEK Power’s 167 kVA pad mount transformer is engineered differently from the pole-mounted version, even with the same 167 kVA rating.
167 kVA pad mounted transformer is an independent three-phase winding design, and it complies with the ANSI/IEEE C57.12.34 standard, equipped with high and low voltage cabinets.
It adopts a fully sealed rectangular steel tank. It is housed inside a lockable, tamper-resistant metal cabinet. It has separated high-voltage and low-voltage compartments.
Instead of hanging on utility poles, it is installed on a concrete foundation pad at ground level. It is designed for underground cable terminations.
OMEK Power's 167 kVA Single Phase Pole Mounted Transformer
Low-voltage dual 230V windings, it is able to output 460V. Compared with the old version, the power loss of the line of our updated single-phase transformer is only a quarter. The 167 kVA 230 volts 1 phase distribution transformer can be combined in three units to form a three-phase transformer group transformer banking.

FAQ
Have any questions? We’re here to help you out.
The 167 kVA transformer can be designed as either single-phase or three-phase. The 167 kVA single phase transformer is generally more commonly the oil-immersed pole mounted type. It is used in places where single-phase loads are required, such as rural overhead distribution and light commercial, etc. It can also be designed as a pad mount style.
The 167 kVA three phase transformer meets the three-phase load and is usually in the pad mounted form. In some countries, the 167 kVA three phase transformer is not a standard product and needs to be customized.
Both transformers are liquid immersed (oil-immersed) distribution transformers, but there are many differences between them.
