Flexible & electrical connections

Laminated & Insulated Flexible Busbars Isoflexx®

Whether as a moving component in solid busbar systems, for connection to generators, transformers, switchgear and switching devices, as a supply line to machine switches and immersion baths, or as a riser in switchgear – Laminated Insulated Flexible Busbars Isoflexx® are innovative electrical connections for your low-voltage installation.

The loose lamellea lying in the insulation offer excellent flexibility and are also suitable for drilling or punching.

Conductor material Laminated Isoflexx®

We manufacture Laminated Insulated Flexible Busbars Isoflexx®  in cross-sections from 21.6 to 1200 mm². The copper lamellea are manufactured from highly conductive Cu-ETP.

  • Electrical conductivity 58 MS/m
  • Tensile strength 200 MPa [R200]. 
  • Lamella thicknesses from 0.5 mm – 1.0 mm 
  • Cu-ETP bare or Cu-ETP tinned (more corrosion resistant)

Isoflexx® Connections

In the manufacturing of technically advanced connectors made of different materials, EMS has rich experience.

Press welded connections (bare copper only) on one or both sides, have excellent conductivity due to their molecular bonding. The connection surfaces can be drilled, milled and bent.

Customized connections on request!

Characteristics insulation

Resistant Insulated Flexible Busbars Isoflexx®

Our Isoflexx® Classic & Premium (105-190 °C) allow higher temperatures than PVC or XLPE cables (70-90 °C). As a result, a significantly higher current carrying capacity can be achieved. Isoflexx® insulation is resistant and has reinforced edges to withstand high operating voltages. The homogeneous, stress-free insulation prevents cracking at edges. Isoflexx® busbar insulations are available in various colors and comply with the RoHS directive.

Isoflexx® Premium

The halogen-free silicone insulation of Isoflexx® Premium is self-extinguishing, produces only a very small amount of toxic smoke in case of fire, and is therefore often used in public buildings. The insulation hose is a homogeneous profile which is pulled over the conductor material.

NEW! Isoflexx® Rail

Isoflexx® Rail’s halogen-free TPE insulation generates only a very small amount of toxic smoke in the event of fire and can therefore also be used in public facilities. Isoflexx® Rail insulation also meets the flame retardant requirements for rail applications – for greater safety for people and railroads.
