ERICO Flexible Wire Replacement General Product Line Information
ERIFLEX® FLEXIBAR - Flexible Wire Replacement
NEW Generation Flexible Wire Replacement
Patent pending insulation on ERIFLEX FLEXIBAR
ERIFLEX FLEXIBAR Flexible
Wire Replacement - a preferred
conductor
• ERIFLEX FLEXIBAR is formed with multiple
layers of thin electrolytic copper, available in
plain or tin plated
• ERIFLEX FLEXIBAR connections are made by
punching and bolting directly through the
laminates or by clamping or welding (using
CADWELD®). There are no lugs to purchase,
helping to eliminate faulty connection problems
and making installation simpler and faster
• The insulation is a high-resistance, self-
extinguishing PVC or silicone compound
Superior Flexibility
ERICO’s exclusive manufacturing process offers superior
flexibility:
• Copper laminates are free to slide within the insulation
• High insulation quality
• Wide variety of bending, twisting & folding possibilities
NEW
Innovative patent pending insulation*
ERIFLEX FLEXIBAR has added grooves on the inner surface of
the insulation sleeve to improve sliding between the central
conductor and the insulation material. The grooves help
reduce the contact surface between the central conductor
and the insulation material. This results in improved flexibility
of the flexible busbar. Result: <20% of the inner surface is
in contact with the central conductor. This ERICO patentpending idea makes ERIFLEX FLEXIBAR more flexible than
ever, and allows users to optimize the design of their
electrical power connection.

Skin Effect on A.C. Application
COPPER CABLE ERIFLEX FLEXIBAR
OR
- Requires less installation space when
compared to cable
- Reduces the length and number
of conductors, reducing weight
- Insulation allows for closer spacing
than traditional busbar designs.
Cost Savings
- Eliminates cost and installation of lugs
- Reduces inventory costs
Improves Reliability
- Connection is made directly to
ERIFLEX FLEXIBAR thus eliminating
the cable lug connection
- Excellent resistance to vibration
- No crimping
Aesthetics
- Improves design flexibility and
panel access
