    KAPTON® polyimide tape is formed by the polymerisation of an aromatic dianhydride and an aromatic thiamine. These tapes can be used over a wide temperature range.


Electrical insulating laminates

UPM and EPGC panels and components

High chemical and temperature resistance are their characteristic features, have very good mechanical properties and high thermal and electrical insulation parameters.



Products Georg Jordan GmbH

Manufacturer of insulating components for the electrical and railway industries.



VOLTROG Sp. z o.o. was established in 1999, and at the time of its founding it dealt exclusively with the warranty service of transformers for their renowned manufacturers; at a later stage it began to implement technological solutions mainly concerning the cutting of soft and hard electrical insulating materials.

Electrical insulating materials are generally employed in the electrical industry. Their task is to insulate individual machine components, electrical equipment as well as electrical cables. They play a very important role in terms of providing safety. Why? Because it is through electrical insulating materials that electrical conductivity can be retained. In many cases, the use of this type of material is mandatory because conductivity could pose a risk to human life or health, as well as damage to various types of equipment and objects.

In the offer of the Voltrog store you will find
all you need!

Our company is pleased to present you with a wide range of high-end products, the robustness and quality of which are confirmed by numerous tests and studies. We can divide the products we offer into hard electrical insulating materials, flexible electrical insulating laminates and bolts.

Hard insulating materials – are mainly used as construction materials with electrical insulating properties. Hard insulating materials are used for electric motors, electrical switchgears and also for the static components of transformers. These type materials include: UPM panels, EPGC panels, electrical insulation moulders, bakelite panels, glass-epoxy profiles and Beech profiles and moulders.

Flexible electrical insulation laminates – are the primary insulation for electric motor windings and transformer windings.

Bolts – our range of bolts includes: eye bolts, wing bolts, as well as countersunk and hexagonal head bolts.
