Expertise & Raw Material

INNOVATIONS are rigorously prioritized at HEW-KABEL and have always provided invaluable impetus for developing future-proof technology and processes.

Production competencies

Due to high vertical integration (in-house wire mill, galvaniser, bunch stranding and silicone compounding at our affiliated company SiC Compound) as well as through special patented manufacturing processes e.g. our specially developed PTFE tapes (HEI-Tape®). HEW-KABEL has everything needed to produce individual, customer-specific cable solutions.

Our customers are working in different markets and the product-specific requirements for our cables are accordingly diverse. Whether it concerns a temperature resistance from -273°C to +1550°C, the minimisation of the weight of the cable or an extraordinary mechanical capacity, HEW-KABEL has or is going to develop a solution!

In doing so we supply our project customers with small quantities as well as our contract customers with several kilometres of cable per year.

A Commitment to Competence

One crucial element in our innovative vigor as an enterprise is our superb MATERIAL COMPETENCE.
