Ultraflexx® highly flexible busbars

Q: Which bending radii does Ultraflexx® have?

The bending radii of our Ultraflexx® highly flexible busbars were determined on the assumption that the connections run parallel to each other (regular and flat edge). However, they are only approximate values: Ultraflexx® with a cross-section of 25 m² → ULFX 25 m² = approx. 6 cm → ULFX 25 m² flat = approx. 6 cm Ultraflexx® with a cross-section of 50 m² → ULFX 50 m² = approx. 6 cm. → ULFX 50 m² flat = approx. 6 cm. Ultraflexx® with a cross-section of 100 m² → ULFX 100 m² = approx. 7 cm. → ULFX 100 m² flat = approx. 7 cm Ultraflexx® with a cross-section of 120 m² → ULFX 120 m² = approx. 8 cm → ULFX 120 m² flat = approx. 8 cm Ultraflexx® with cross-section 240 m² → ULFX 240 m² = approx. 9 cm → ULFX 240 m² flat = approx. 9 cm

Ultraflexx® highly flexible busbars are made of flat copper mesh, which are supplied ready for use and thus simplify your installation.

Application area Ultraflexx® highly flexible busbars

Ultraflexx® highly flexible busbars are flexible connectors made of flat copper mesh and reliably absorb vibrations and switching surges.

The press-welded connections are (contrary to the generally available press technology) press-welded over the entire connection cross-section and can be processed like a solid end piece.

Ultraflexx® highly flexible busbars are robustly insulated and are ideal for flexible use of space and are the best alternative to pre-assembled cables. Thanks to our different cross-sections, Ultraflexx® highly flexible busbars can be adapted to a wide range of equipment and used as connectors between various control cabinet modules and units.

What benefits do Ultraflexx® connections offer?

Connections with press-welded connection ends

The connection ends can be machined like a solid end piece.
They are vibration-resistant and allow minimal contact resistance to pass through.
Lower power loss and smaller voltage drop.
No corrosion and therefore no deterioration of the connection resistances over time

Which bending radii does Ultraflexx® have?

The bending radii of our Ultraflexx® highly flexible busbars were determined on the assumption that the connections run parallel to each other (regular and flat edge). However, they are only approximate values:

Ultraflexx® with a cross-section of 25 m²

→ ULFX 25 m² = approx. 6 cm

→ ULFX 25 m² flat = approx. 6 cm

Ultraflexx® with a cross-section of 50 m²

→ ULFX 50 m² = approx. 6 cm.

→ ULFX 50 m² flat = approx. 6 cm.

Ultraflexx® with a cross-section of 100 m²

→ ULFX 100 m² = approx. 7 cm.

→ ULFX 100 m² flat = approx. 7 cm

Ultraflexx® with a cross-section of 120 m²

→ ULFX 120 m² = approx. 8 cm

→ ULFX 120 m² flat = approx. 8 cm

Ultraflexx® with cross-section 240 m²

→ ULFX 240 m² = approx. 9 cm

→ ULFX 240 m² flat = approx. 9 cm
