• Laminate thickness: 0,5 - 0,8 - 1 mm

Insulation

• Self-extinguishing UL 94-V0; black color with a white line
• Thickness: 2 mm ± 0,2
• Allungamento max: 365%
• Hardness: 80 Shore A
• Tensile strength: 19 MPa
• Dielectric strength: 20 kV/mm

Finished product

• Rated voltage: 1000 V AC / 1500V DC
• Working temperature: -40°C ÷ +105°C.

In vs. ΔT

• In = Rated current A
• ∆T= Temperature rise °C
• ΔT= Tf - Ta
• Tf = Working temperature °C
• Ta = Room temperature °C

Reference example

CFX 4X20X1
Laminate number: n = 4
Laminate width: L = 20 mm
Laminate thickness: s = 1 mm

Icc - effective short-circuit current for 1 s

Icc parametres calculation

Initial temperature:
105°C - maximum working temperature of the conductor

Final temperature:
160°C - limit of temperature for PVC insulation compliant with IEC 60724 for cross-sections < 300 mm2
140°C - limit of temperature for PVC insulation compliant with IEC 60724 for cross-sections > 300 mm2
