WHY USE VFD CABLES? HELUKABLE ANSWERS

January 6, 2023

The current NFPA guidelines require RHH, RHW, RHW-2, XHH, XHHE or XHHW-2
insulation for use inside the motor’s control panel or cabinet, but the
expectation is this requirement will move to include cable used in external
wiring of VFD applications in the upcoming years

Why Use VFD Cables? VFD cables are a critical component to extend a motor’s life
cycle within a VFD system. Three areas where VFD cables set themselves apart
from traditional tray-rated power cables are:

1. Address high and low frequency noise issues with proper shielding

Shielding on cables is what prevents systems from interacting with each other.
In short, a cable’s shield is its defense against noise. THHN and most generic
control/tray cables are constructed using either an aluminum shield or they are
unshielded. HELUKABEL’s VFD cables are constructed using either a foil (100%
coverage) + tinned copper braid (85% coverage), or a triple shield comprising of
a semi-conductive fleece + foil + braid shield (80% coverage). Cables with the
proper shielding prevent the VFD system from radiating electrical noise that can
interfere with surrounding networking, instrumentation, wireless communication,
and industrial devices.

2. Ability to withstand voltage spikes/reflected wave voltage

A cable combats voltage spikes with insulation material and wall thickness.
HELUKABEL’s VFD cables use XLPE insulation as its conductor insulation. XLPE has
a much lower capacitance (higher corona inception voltage) than THHN and generic
control/tray cable which just use PVC. This is particularly important in wet or
damp environments as PVC is more susceptible to absorbing moisture, which
results in less than half the insulation capability of XLPE. The wall thickness
of a VFD cable tends to be thicker allowing it to withstand voltage spikes
significantly better.

The current NFPA guidelines require RHH, RHW, RHW-2, XHH, XHHE or XHHW-2
insulation for use inside the motor’s control panel or cabinet, but the
expectation is this requirement will move to include cable used in external
wiring of VFD applications in the upcoming years.

3. High temperature resistance

A cable’s type of insulation plays a significant role in how it responds to
thermal stress. Thermoset insulation won’t melt or drip in higher temperatures
like the thermoplastic insulation found in THHN and generic control/tray cables.
If thermoplastic insulation is used, you run the risk that it will melt, drip,
or simply deform, which reduces the insulation properties, and can cause damage
to critical and expensive equipment/machinery.

Complete Your Cable System

EMC glands improve VFD cable perfromance and protect your equipment from the
harmful effects of electromagnetic interference

Further enhance your electric motor’s lifespan by using EMC glands to protect
your equipment from electromagnetic interference. EMC glands perform a key
function in EMC protection by deflecting electromagnetic waves over the housing
surface at a critical transition point – entry into the enclosure – in order to
protect the exposed cables inside.

Thanks to their enlarged contact surfaces, EMC cable glands improve conductivity
between the cable shield and gland on the enclosure housing. With their copper
beryllium contact system, products such as the
HELUTOP®  MS-EP and  MS-EP4 ensure excellent shielding attenuation and current
dissipation. Contact is made automatically when the gland is tightened, and the
polyamide PA 6 insert provides perfect strain relief.

Put to the Ultimate Test Cables and wires in industrial robots and other moving
machine parts are often required to withstand extreme stresses caused by
torsion. Find out how HELUKABEL puts their cables to the ultimate test. Read
