VFD Cable 3X35 3X50 and Earth Core XLPE Insulation LSZH Sheathed Power Cable
VFD cable is used to connect variable frequency drive system to a motor. A lot of times, they are found in industrial or factory environments and can be used in bottling equipment, grinding machines, data processing equipment, and automated servo systems.
VFD cable is designed to withstand the unique challenges of variable frequency drive applications, also called alternating or variable speed drives. VFDs control the amount of electricity delivered to a motor at any given time. Because they can change the amount of current, they minimize energy waste and allow for a higher level of process control.
These systems need to convert energy from AC to DC current, and then back to AC. These energy conversions result in a range of hazards the cable must be able to withstand.
Now this technology is so advanced, the other components used in VFD systems can handle the conversions and their consequences fairly easily, making VFD cables the most susceptible to damage. Choosing an inappropriate VFD cable can lead to interference with nearby equipment or system failure.
Variable frequency drive cables are constructed with these issues in mind. Shielded VFD cable combats the problems of high frequency noise and interference. Common shielding materials include copper tape, combination shielding, and continuously corrugated and welded shielding.
Insulation should be chosen based on its electrical and physical properties. Because variable frequency drive cables are often used in hazardous factory settings, they will probably need to resist impact, crushing, oil, etc. They may also need to be flexible. The cable’s insulation must exhibit high temperature stability in order to deal with potential temperature fluctuations. Overall, thermoset insulations such as XLPE are best for VFD applications.
