The MC Luminary cable features two single
copper THHN conductors, one single THHN
insulated ground, and a twisted jacketed
pair of TFN conductors. The MC Tuff Luminary
cable is a lightweight galvanized steel
interlocked armor cable, and the MC-Lite
Luminary cable is an interlocked aluminum
armor cable. Both are offered in 120/208
or 277/480 conductor designs with a TFN
conductor low voltage control assembly
under one armor.
MC Luminary cables are designed to save
time and significantly reduce installation
costs. By coupling the standard power wiring
for lighting fixtures with the low voltage
control wiring under a single armor, a single
MC Luminary cable will do the job of two
cables when connected to LED fixtures,
dimmers, switches, occupancy sensors and
other controls.
MC Luminary cable reduces procurement
time, shipments, installation time, and waste
on the project, and contributes to the
desired outcome for LEED certification status
of Smart building designs.
New HFFR compounds
Teknor Apex Company has launched new
halogen-free flame retardant jacketing
compounds for data center cables,
control cables, energy cables, and other
demanding applications. The compounds
are said to exhibit a higher level of flame
retardance than other high-performance
HFFR materials, without compromising
physical or electrical properties.
Halguard
®
58300 series HFFRcompounds with
limiting oxygen indices in the 53–56 percent
range enable cables to pass the stringent
UL1685 vertical tray test (CSA FT4 / IEEE 1202)
and achieve a UL94 rating of V-0 with test
specimens as thin as 1/40 inch (0.635mm).
The compounds are developed to provide
outstanding flame performance while
exhibiting the same physical and electrical
properties of other high-performance HFFR
materials. Available grades are in the 48-52
Shore D hardness range.
Teknor Apex recommends Halguard 58300
series compounds for data centers and
other applications requiring exceptional
flame retardance, one example being the
extensive ‘server farms’ operated by Internet
companies.
“We believe that Halguard 58300 series
compounds are the most flame-retardant
HFFR products on the market,” said Michael
