About this product

Global VFD Cables

Elegar Kerpen, one of the most trusted wires and cables manufacturers in India, manufactures VFD cables that meet the demands of modern drive systems. With voltage grades up to 1800/3300V AC, flexible copper conductors, and insulation options including XLPE, EPR and HEPR, every cable is built to protect your motors and reduce downtime, making it a reliable choice for engineers across industries.

What a VFD cable does
Variable Frequency Drive systems create extreme conditions for cables, including high-frequency switching, voltage spikes and electromagnetic interference that regular cables cannot handle. A VFD cable is designed specifically for these conditions, offering strong insulation, proper shielding and a solid build that keeps industrial systems running without interruption.
Use cases

Applications of VFD Cables

The metallic screening layer reduces electromagnetic noise, contains the electric field around the core, and earths voltage spikes produced during drive operation — making VFD cables suitable across many industrial sectors.

01
Industrial Automation
Connecting motor drives to automated machinery where accurate speed control is critical. They suppress noise that would otherwise disturb control signals and nearby low-voltage wiring, keeping operations stable.
02
Oil & Gas
In offshore and hazardous locations, a VFD motor cable must handle mechanical stress, chemical exposure and high voltage transients at the same time. ZHFR and SHF1/SHF2 sheathing options are built for these conditions.
03
Mining
Mining sites need cables that can take abrasion, moisture and constant movement. VFD cables used in mining consistently handle the high-frequency switching of heavy machinery without any loss in signal quality.
04
Chemical & Process Plants
These facilities use variable frequency drive systems to control pump and fan speeds. VFD cables with proper shielding prevent interference with sensitive instruments running nearby on the same installation.
05
Marine & Offshore
Medium voltage VFD cable used on vessels and offshore platforms faces vibration, saltwater exposure and strict electrical compatibility requirements. Our cables are constructed to perform reliably in all these conditions.
06
HVAC & Building Services
Large HVAC systems use VFD-controlled motors for energy-efficient operation. Correctly rated VFD cables stop noise from affecting building control systems and communication networks running in the same area.

Product advantages

Why Elegar Kerpen VFD Cables?

Eight measurable advantages built into every cable, from manufacturing floor to field installation.

Strong Conductor Design
Circular electrolytic bare or tinned copper conductors, in stranded or flexible form, make installation easy and ensure long service life in high-movement environments.
Multiple Insulation Options
XLPE, EPR and HEPR choices cover a wide range of temperature and chemical resistance needs, making it straightforward to pick the right cable for your drive application.
Reliable EMC Shielding
Copper tape with copper wire braid, or double copper tape with concentric braiding, creates a low-resistance ground return path that controls high-frequency drive noise.
Sheath for Every Environment
PVC, ZHFR, SHF1 and SHF2 sheath choices cover site conditions from standard industrial setups to low-smoke, halogen-free installations in enclosed spaces.
High Voltage Rating
Rated up to 1800/3300V AC to handle voltage spikes that go beyond the normal operating level, a regular occurrence in high-frequency switching systems.
Motor Bearing Protection
Proper screening gives high-frequency ground currents a defined return path, lowering the shaft voltages that slowly damage motor bearings in drive-fed systems.
Halogen-Free & Low Smoke
ZHFR, SHF1 and SHF2 options limit smoke and toxic gas emission, meeting safety requirements for marine vessels, tunnels and public infrastructure.
Application-Led Engineering
Proven cable construction combined with hands-on application knowledge, so specifications are matched to the drive, the motor and the site, not just the catalogue.
Support FAQ

Frequently Asked Questions

Common technical and commercial questions about Elegar Kerpen VFD cables.

What is a VFD cable and how is it different from a regular power cable?
A VFD cable is built to handle the high-frequency voltage spikes, electrical noise and stress produced by variable frequency drive systems. Regular power cables are not rated for these conditions and can fail or degrade much faster in such environments.
What is the VFD cable length limitation I should be aware of?
Cable length affects how voltage behaves in VFD systems. Longer runs increase voltage reflection, which can harm motors and drives. It is always best to follow the drive manufacturer's guidelines and plan cable runs carefully, especially for distances beyond recommended limits.
Which industries use medium voltage VFD cable most often?
Medium voltage VFD cable is commonly used in oil and gas, mining, marine and large industrial processing plants where high-power motors need to be controlled by variable frequency drives and standard low-voltage cables are not suitable.
What types of insulation does Elegar Kerpen offer on its VFD cables?
Elegar Kerpen provides XLPE, EPR and HEPR insulation options. Each type suits different temperature ratings, flexibility needs and levels of chemical resistance based on where the cable will be used.
Can VFD cables help reduce motor bearing damage?
Yes. A well-shielded VFD cable provides a proper path for high-frequency ground currents, which lowers shaft voltages that can slowly damage motor bearings. This is a known issue in systems running on variable frequency drives.
Are Elegar Kerpen's VFD cables available with halogen-free sheathing?
Yes. Elegar Kerpen offers ZHFR, SHF1 and SHF2 outer sheath options that are halogen-free and produce low smoke. These meet safety standards for enclosed spaces, marine vessels and public infrastructure projects.
How do I choose the right VFD motor cable for my application?
The right choice depends on voltage rating, conductor size, insulation type, shielding and the environment where the cable will be installed. As one of the established wires and cables manufacturers in India, Elegar Kerpen's technical team can help you find the right specification for your drive system.
Which standards do Elegar Kerpen VFD cables comply with?
Our VFD cables are designed and produced in line with IS:7098 (Pt-1), IEC 60502-1, BS:5467, BS:6346 and AS/NZS 5000.1. These standards help ensure consistent quality, resistance to electrical stress and suitability for VFD motor cable installations across industrial, commercial and process environments.
