CE: European Union safety mark of conformity. Type 121: Sheath material is EVM-1, suitable for charging mode 1 of IEC 61851-1 (rated voltage 300/500V). Specification range: 3x1.5mm ~3x2.5mm Type 122: Sheath material EVM-2 for charging mode 1 of IEC 61851-1 (rated voltage 300/500V). Specification range: 3x1.5mm�²~3x2.5mm�² Type 123: Sheath material EVM-1, suitable for charging mode 1, 2 and 3 of IEC 61851-1 (rated voltage up to 450V/750V). Specification range: 3x1.5mm~3x35mm, 4x2.5mm ~4x35mm, 5x2.5mm~5x35mm. Type 126: DC charging cable with rated voltage 0.6/1KV AC or 1.5KV DC, sheathed in EVM-1, suitable for charging mode 4 of IEC 61851- 1. Range of sizes: 2x4mm~2x150mm+ earth wire 4mm~95mm. EVI-1 and EVI-2: EVI is the name given to halogen-free insulating compounds in the IEC62893 and EN50620 standards. Only EVI-2 can be used to insulate power lines, while EVI-1 and EVI-2 can be used to insulate control/signal lines.The performance requirements of EVI-1 and EVI-2 are different, for example, the standard requirements are: tensile strength of EVI-15N/mm², elongation at break 300%, while the tensile strength of EVI-2 is 8.0N/mm, and the elongation at break 200%. The key difference is that EVI-1 has a requirement for high temperature pressure testing and EVI-2 has a requirement for thermal extension testing. So EVI-1 needs to be a thermoplastic material (TPE) and EVI-2 needs to be a halogen-free cross-linked material (XLPO). EVM-1 and EVM-2: EVM is the name of halogen-free sheathing compounds for cables in IEC62893 and EN50620 standards.EVM-1 is applied to Z5 of EN50620 and 121 and 123 and 126 of IEC62893, and EVM-2 is applied to Z6 of EN50620 and 122 of IEC62893.The performance requirements of EVM-1 and EVM-2 are different. EVM-2 performance requirements are different, for example, the standard requirements: EVM-1 tensile strength â?¥ 20N/mm �², elongation at break â?¥ 300%, tear resistance â?¥ 40N/mm �²; while EVM-2 tensile strength â?¥ 10N/mm �², elongation at break â?¥ 150%, tear resistance â?¥ 10N/mm �², the aging temperature of the mechanical properties test after aging is different, the most important differences between The key difference is that EVM-1 has the requirement of thermal shock and high temperature pressure test, and EVM-2 has the requirement of thermal extension test. So EVM-1 needs to be a thermoplastic material (TPU) and EVM-2 needs to be a halogen-free cross-linked material.
