toxic gases when compared traditional cable materials. Toxic gases are not only a hazard to humans, but they can have a corrosive effect on equipment. Halogen-free materials protect personnel, but may still generate signiÞ cant smoke that can hamper visibility. LSZH materials allow visibility to be main- tained by generating very low amounts of smoke. Conventional limited-Þ re-hazard cables offer low combusti- bility to minimize the growth and spread of a Þ re. They also produce varying degrees of corrosive gases, carbon monoxide, and smoke and can fail within minutes. C-Lite FR cables offer a composite conductor insulation that combines limited-Þ re-hazard performance with Þ re resistance to allow prolonged operation during Þ reÞ ghting and evacu- ation. They are an excellent choice for alarms, emergency lighting, and controls. Using a mica wrapping under the main insulation, these ca-bles can continue to operate even as the jacket and insulation materials fail. Mica remains stable at very high temperatures, providing a physical barrier and an electrical insulation under pyrolysis conditions. Such operation can be critical to safety, alarm, and control systems, allowing circuit continuity and preventing short circuits for over 120 minutes at temperatures to 1000¡C.Full Range of Multiconductor CablesAs shown in Figure 4, C-Lite cables are available in com- mon cable conÞ gurations needed for offshore and marine use in power, lighting, communications, and instrumentation. Op- tions include  Conductor sizes from 0.50 mm2 to 10 mm2 (24 to 12 AWG) for both signal and power  Multiconductor, multipair, multitriple, and multi quad conÞ gurations Conductor counts ranging to 50 singles, 37 pairs, or 24 triples  Stranded conductors for ß exibility Unshielded, foil shielded, braid shielded, or foil/ braid shielded Armoring Ratings of 150/250 V or 600/1000 V C-Lite is also available as discrete hook-up wire. The cables come in two main families: CL90 and CL105. CL105 cables use a cross-linked LSZH jacket and offer SHF2 resistance to oils, solvents, fuels, and mud. While most marine agencies require an operating temperature range from -15¡C to +105¡C, CL105 cable offers a more generous range from -30¡C to +120¡C.O shore Systems Fig. 4.
