We manufacture and supply electrical insulators, conductors and connectors for medium and high voltage applications for railway infrastructure (overhead catenary and 3-4 rail traction power systems), power stations, small army bases, ports and large industrial estates.

We manufacture in a number of different compounds but predominantly EPDM, silicone and DMC. Parts and assemblies are produced to a customer’s specification using very effective compression moulding techniques. These are particularly suited to medium volume, specialist applications. Unlike many insulator manufacturers, Dellner Polymer Solutions design and manufacture the tooling in-house, enabling customers to develop new insulators with shorter lead-times.
