Variable Frequency Drive (VFD) Cable
Application
VFD cable is primarily used for connecting the cable between the variable frequency power supply and the variable frequency motor, as well as for transmission and distribution lines with a rated voltage of 1 KV and below. It is especially suitable for industries such as:
- Paper manufacturing
- Metallurgy
- Metal processing
- Mining
- Railway
- Food processing
Standards
- Complies with relevant international and industry standards.
Construction
The cable structure includes:
- Three main insulated cores and three earth insulated cores.
- Outer layers: Wrapping layer, copper tape shield, and outer sheath.
- 3+3 core structure: Provides strong voltage shock resistance, enabling the cable to withstand high-frequency pulse voltages and frequent frequency conversion, offering excellent protection for frequency conversion appliances.
Features
- Rated voltage: 0.6/1 kV.
- Conductor temperature:
- Long-term maximum operating temperature: 90℃.
- Short-circuit maximum temperature: 250℃ (for a short duration).
- Installation temperature: Not less than 0℃.
- Minimum bending radius: Not less than 15 times the cable diameter (15D).
