PRODUCT PORTFOLIO
Among the numerous products supplied for different applications in the cables market, the Mixer’s portfolio includes a wide range of rubber-based solutions, ensuring high-quality standards throughout the entire manufacturing process, from the raw material selection to the final product testing. The Italian company has solidified its position worldwide as a reference point for medium voltage insulation, creating a specialized production line that emphasizes meticulous attention to all details and achieving complete cleanliness.
The medium voltage insulation portfolio includes grades for applications up to 95kV, based on full EPR, EPDM, and EPDM-PE blends, comprising solutions with and without lead. The lead-free grades have been specifically developed to minimize the environmental impact, keeping excellent insulating performances in compliance with the lead-free directive necessary to access the European market, the RoHS regulation. All these compounds are fully compliant to the international standards for 90°C and 105°C operating temperatures and they can be employed both for static and dynamic applications, even in extremely cold environments down to -40°C. Moreover, taking advantage of the elastic behaviour of the fully rubber-based compounds, solutions suitable for multicore cables have gained momentum in view for voltages up to 69 kV.

RECENT DEVELOPMENTS
Recently, Mixer has enriched its offer with increased flexibility grades that avoid the scorch issues especially at high extrusion speed. EKOPREN® 3IS73F and 3IS75F for applications up to 35 kV, and EKOPREN® 3IS74F for applications up to 69 kV represent such solutions, always maintaining the highest level of performance. Besides, due to the increasing interest for rubber cables suitable for applications up to 95 kV, a new grade named EKOPREN® 3IS721 is a result of a deep investigation and study of the raw materials capable of providing the highest quality in terms of insulation behaviour and electrical properties. Typical electrical tests are the volume resistivity, the dielectric strength, and the loss factor.
Finally, focusing the attention on the multicore applications, it is worth noting the new grades such as EKOPREN® 3IS01A and EKOPREN® 3IS691 which, together their lead-free counterparts, ensure low deformation in processes that involve a second step of peroxide-induced crosslinking for the sheathing extrusion. These grades are capable of maintaining constant the diameter of each insulation core against the high pressure generated by the outer sheath, ensuring a high level of flexibility and avoiding partial discharges or breakdown issues. Moreover, among them, EKOPREN® 3IS041 consists of a new grade for the wind turbine applications. By paying close attention to every detail, the diverse range of products in the medium voltage compounds field includes environmentally friendly lead-free solutions and fully rubber-based blends suitable for multicore cables.
