™
Description
General Cable's Zephyr2000 Type RHH/
RHW-2 2000 V rated AA-8000 single
conductor is suitable for use in special
applications, such as wind power generation.
As with all AA-8000 aluminum conductors,
this high quality product is dependable and
offers tremendous flexibility. It meets the
requirements of the applicable Underwriters
Laboratories, Inc. standards and is
approved for use in accordance with the
recommendations of the National Electrical
Code (NEC). AA-8000 alloy conductor is
recognized by ASTM.
General Cable offers a broad
range of wind generation,
transmission and distribution
cables that link turbine sources
to the grid and beyond.
Zephyr2000 is the aluminum
conductor solution for wind
power generation from
the turbine to the
step-up transformer.
Application
Wind power generating installations may
require conductor insulations rated higher
than 600 V to transfer the generated power
to the step-up transformer. 2000 V rated
Zephyr2000 Type RHH/RHW-2 AA-8000
conductors are manufactured for these
specific applications to satisfy customers’
specifications. Type RHH/RHW-2
conductors are installed in raceways in
accordance with the requirements of the
NEC and may also be used in cable trays
when marked for “CT use.” Contact
General Cable to ask about conductors
rated for use in cable tray.
Marking
Conductors will bear the following surface marking:

NOTES
1. Ampacities are based on conductor operating temperatures
only and do not take voltage drop into consideration.
2. A neutral conductor which carries only the unbalanced
current from other conductors, as in the case of normally
balanced circuits of three or more conductors, is not required
to be counted in determining Ampacity Adjustment Factors.
But in a three-wire circuit consisting of two phase wires
and the neutral of a four-wire three-phase Wye-connected
system, a common conductor carries approximately the
same current as the other conductors and must be counted
in determining ampacities.
3. Based on Ambient Air Temperature of 30°C (86°F).
4. See termination provisions for conductor sizing as given
in Underwriters Laboratories Electrical Construction
Materials Directory, “Equipment for Use in Ordinary
Locations.”
