INSULATING FLEXIBLE COPPER BARS

Product catalog summary
General Characteristics:
The document outlines the specifications of insulated flexible copper bars, which include copper type Cu-ETP 99.9%, insulation voltage of 1000V AC / 1500V DC, operational temperature range from -40°C to +105°C, insulation thickness of 1.5 / 2 mm, dielectric strength of 20 kV/mm, and a standard length of 2 meters. These bars are also available in tinned copper and are UR homologated for the North American market.
Ordering Codes:
A detailed list of ordering codes is provided, specifying dimensions, section in mm², and packaging details. Dimensions are given as width x thickness x number of sheets.
Other Characteristics:
The copper bars are composed of a stack of copper sheets with a flame-retardant PVC insulating layer, allowing flexibility in bending and twisting. They offer a 40% reduction in copper section compared to normal cables for the same nominal current.
Thermal Increases and Current Capacities:
A table is included showing the thermal increase (ΔT) and corresponding current load capacities for various copper bars.
Derating Coefficients for Parallel Use:
Recommendations for derating current capacity when using two or three bars in parallel are provided, with specific coefficients for different thickness ranges.
Installation Instructions:
Flexible bars should be mounted on insulating supports with a maximum distance of 400 mm between them. Bars should be connected using collars, with distances between collars based on electrodynamic stresses in case of a short circuit.
Specifications:
The document specifies distances required between collars based on maximum current (Icc max) in kA effective: 20 kA: 350 mm, 25 kA: 200 mm, 35 kA: 100 mm, 45 kA: 70 mm.
Mounting Instructions:
Flexible bars should be mounted on insulated supports with a maximum distance of 400 mm between them and held together with straps. The distance between straps is determined by electro-dynamic constraints in the event of a short-circuit.
Recommended Distances Between Straps:
Recommended distances between straps based on maximum current (Icc max) in kA effective are identical to collar distances: 20 kA: 350 mm, 25 kA: 200 mm, 35 kA: 100 mm, 45 kA: 70 mm.

INSULATING FLEXIBLE COPPER BARS-4

Altre caratteristiche: Other characteristics: Sono costituite da un pacco di lamine di rame inserite e protette da un isolamento in PVC autoestinguente (grado V0 secondo UL 1581). They consist of a stack of sheets of copper inserted and protected by a PVC insulating layer flame retardant (V0 according to UL 1581). All’interno dell’isolamento le lamine sono libere di scorrere offrendo illimitate possibilità di piegature e torsioni, facilitando la preparazione delle parti terminali che sono realizzate sguainando il pacco lamellare e forando direttamente lo stesso. Inside the insulation layer, the...

INSULATING FLEXIBLE COPPER BARS-7

Mounting instructions Le barre flessibili devono essere fissate su supporti isolanti ad una distanza massima di 400 mm. E’ necessario unire le barre tra di loro tramite collari. La distanza tra i collari è funzione delle sollecitazioni elettrodinamiche in caso di corto-circuito. Flexible bars should be mounted on insulated supports with a maximum distance of 400 mm. Bars should also be held together with straps. The distance between successive straps depends on the electro-dynamic constraints in the event of a short-circuit. Qui sotto vengono indicate le distanze previste tra i collari: The table...
