Combination of features of cables

◦flexibility (in one direction)


 and rigid Cu bar

◦higher current carrying capability

◦mechanical withstand (in the other direction)

◦better electrical contacts

◦more compact than cables

Isoflexx® consists of

 Copper lamellas of 0.5 / 0.8 and 1mm

◦high grade copper E-Cu 57, F20

◦up on request as a tinned version


◦giving the right compromise between flexibility and stiffness (not too loose, not too tight)

◦high quality, high temperature PVC (Isoflexx® Classic), available in different colors

◦halogen free, high temperature Silicone (Isoflexx® Premium)

◦halogen free, high temperature Santoprene (Isoflexx® Supreme), more expensive, up on request

Isoflexx® is used

 for flexible connection between bars and electrical devices (switches & switchgear, transformers, generators, etc.)

 to substitute bars and cables within switchgear for different advantages

 to create easy-to-install prefabricated connection kits (e.g. Delta-Star-Starters)

 to connect moving machine parts

 to absorb mechanical shocks (e.g. circuit breaker connections)
