In presenting the interpretation of the designations of the European standards, we can organise them as follows:
Rated voltage class U0/U.
- U0 is the value of the voltage effective between the conductor with insulation and the shield and dielectric.
- U is the effective value of the voltage between any two phases of a multi-core cable or a single-core cable.
CE Marking.
- The EU safety conformity mark, indicating that the product meets the standard requirements of a series of European directives on safety, health, environmental protection and consumer protection.
Model 121.
- The jacket material is EVM-1 for charging mode 1 of IEC 61851-1 (rated voltage 300/500V).
- The specification range is 3x1.5mm²~3x2.5mm².
Model 122.
- Sheathing material EVM-2, also suitable for charging mode 1 of IEC 61851-1 (rated voltage 300/500V).
- The specification range is 3x1.5mm²~3x2.5mm².
Model 123.
- Sheath material EVM-1, suitable for charging modes 1, 2 and 3 of IEC 61851-1 (rated voltage up to 450V/750V).
- Wider range of specifications including 3x1.5mm²~3x35mm², 4x2.5mm²~4x35mm², 5x2.5mm²~5x35mm².
Model 126.
- DC charging cable rated at 0.6/1KV AC or 1.5KV DC, sheath material EVM-1.
- Suitable for charging mode 4 of IEC 61851-1.
- The specification range is 2x4mm²~2x150mm² + ground 4mm²~95mm².
EVI-1 and EVI-2.
- EVI stands for halogen-free insulation compounds according to IEC 62893 and EN 50620.
- Only EVI-2 can be used for power line insulation, EVI-1 and EVI-2 can be used for control/signal lines.
- EVI-1 and EVI-2 have different performance requirements such as tensile strength, elongation at break, etc.
- EVI-1 requires the use of a thermoplastic material (TPE), while EVI-2 requires the use of a halogen-free cross-linked material (XLPO).
EVM-1 and EVM-2.
- EVM stands for halogen-free sheathing compounds for cables in the IEC 62893 and EN 50620 standards.
- EVM-1 and EVM-2 have different performance requirements, such as tensile strength, elongation at break, and tear resistance.
- EVM-1 requires the use of a thermoplastic material (TPU), while EVM-2 requires the use of a halogen-free cross-linked material.
