Applications

This cable is intended for fixed installation in wind turbine towers. Good resistance to temperatures, oils, ozone and fire. This cable is intended for use in solar power generation applications to connect the inverter to transformer where high flexibility is required, commonly applied to prefabricated inverter and transformer skids.  Additionally, this cable is appropriate for tight battery applications, as well as superior alternatives to battery cable. TOWERGUARD CCA®  can also be used for secondary voltage resistance welding leads and in power supply applications not exceeding 2000V volts.

Construction
Nominal voltage: RHH or RHW-2 2000V UL
Conductor: The conductor shall be a flexible Copperclad Aluminum (CCA), an electrical conductor that has an outer sleeve of copper metallurgically bonded to a solid aluminum core. The combination of these two metals makes it uniquely suited to many electrical applications where weights to electrical conductivity issues are important. This bimetallic wire is much lighter than copper and only slightly heavier than bare aluminum. The density of CCA is about 35% lighter than copper. CCA conducts like copper for AC frequencies. This product meets or exceeds the minimum requirements set forth in ASTM B 566 04.
Separator: A suitable tape separator between the conductor and insulation.
Insulation: Ethylene-propylene rubber (EPR) type EP, meeting UL and ICEA requirements for 90ºC.
Jacket: A heavy duty, thermosetting CPE in accordance with ICEA S-95-658 NEMA WC70 or optional Low Smoke Zero Halogen jacket LSZH.
Jacket Color: Black
Print Legend: TOWERGUARD CCA® (SIZE AWG OR KCMIL) CU CLAD AL UL 217923 RHH or RHW-2 2000V SUN RES OIL RES U.S. Patent No. 8,618,688 (SEQUENTIAL FOOTAGE MARKER)
