APPLICATION
A flexible, braid and foil shielded, 2kV power cable specifically
engineered for use in variable
frequency AC motor drive (VFD) applications.
FEATURES
1. Specially engineered cable design produces a longer cable life
in VFD applications. Overall braid plus foil shield is
engineered with 100% coverage and a surface transfer impedance
<50 milliohms at 10MHz tocontain EMI.
2. Symmetrical insulated ground conductors reduce induced voltage
imbalances and carry
common mode noise back to the drive.
3. High strand count conductors and braid shield design is much
more flexible, easier
to install and more resistant to vibration than Type MC cable.
4.Gexol’s lower dielectric constant (standard XLPEs, EPRs and other
Type P insulation
materials have higher dielectric constants) reduces reflected wave
peak voltage magnitudes. This allows for longer output cable
distances and minimizes the effect of high frequency noise induced
into the
plant ground system.
5. 2kV insulation thickness is used to resist the potential 2-3x
reflected voltages experienced
in 600V VFD applications.
6. Passes the same stringent crush and impact testing required by
UL 2225 for Type MC-HL
7.Gas & vapor tight – impervious to water and air
8.Smaller bend radius (up to 40% smaller) than Type MC
9.Reduced tray fill (up to 35% less) compared to Type MC
10.Considerably more flexible than Type MC
11. Reduced installation time and cost compared to Type MC
12.Glands for this product cost up to 50% LESS than those for Type
MC
VFD 2kV Technical Parameter 3x300MCM+3x6 AWG
