Single and three-phase potential transformers are designed and manufactured by Penbro Kelnick.
Penbro manufactures an innumerable number of transformers, according to customer specifications,
Penbro Kelnick - Transformers & Magnetic Products
Single Phase & 3 Phase Transformers:
Single phase and 3 phase isolation transformers.
Single phase and 3 phase oil-cooled transformers.
Single phase and 3 phase auto transformers.
Toroidal transformers up to 2kVA.
These single phase transformer and 3 phase potential transformers are manufactured from high grade, standard sized materials.
The power range of our transformers varies from a few VA to 1MVA. In most applications where the power requirement exceeds 2kVA,
laminations are cut in-house according to the specified design.
Penbro Kelnick is renowned for our ability to design power transformers with special characteristics.
Dry-type transformers are manufactured to cater for a wide range (3VA to 1MVA) of single phase
and 7VA to 1MVA for three-phase applications.
When required, we also vacuum impregnate our transformers to improve insulation qualities. We also
offer various types of sheet-metal or polyester enclosures. Every transformer dispatched from
the factory has undergone extensive testing according to ISO 9001:2008.
Penbro Kelnick manufactures a wide range of PCB-mount transformers for various applications in
the low to medium-voltage range. These transformers are manufactured with imported bobbins and
lamination materials to enhance their quality and efficiency in order to meet high standards.
We offer the following types of PCB transformers:
Single and three-phase open PCB transformers.
Standard range encapsulated PCB transformers.
Open and encapsulated pulse transformers.
Toroidal and current transformers.
Low profile encapsulated PCB transformers.
M – type transformers.
Most of the small transformers produced at the Penbro factory are units made according to customer specification, and range from 0.5VA to 40VA and in special applications to 100VA.
Custom Made Coils:
A large range of coils, chokes and other magnetic devices are produced for railway applications
and special purposes which include:
Blow-out coils for switchgear.
Filter chokes for harmonic suppression.
Shunt coils for sensing.
Air core chokes for surge suppression.
Penbro Kelnick manufactures replacement parts, which often are obsolete, for many applications. This has contributed
to the fact that we presently manufacture more than 500 different types of inductors annually for special applications
The versatility of our production facilities and experience in railway energy systems ensures that there are few restrictions
in our coil winding abilities. No products are ever “too odd” for us to manufacture – if there is a demand we will design and
build it, an initiative which has shaped our history and reputation.
