Lightweight cables for high-risk or safety-critical applications
Tyco Electronics is expanding its range of lightweight, small-diameter C-Lite cables with a version designed for use in high-risk and safety-critical environments. C-Lite FR cables feature all performance characteristics of the standard C-Lite cable range with the added ability of maintaining circuit integrity for two hours during a 1000degC fire (as defined by IEC 60331). Prototype samples actually survived the fire for eight hours.
Tyco Electronics' range of lightweight, small diameter C-Lite cables typically offers 30 per cent weight savings and 50 per cent volume reductions in comparison with standard commercial cables, and this is achieved without compromising the electrical performance. Designed for installations on ships or rigs (eg engines, general power, lighting, communication and electrical equipment cabinets), the cables also provide excellent performance in oils, chemicals and drilling mud.
With much improved installation and handling capabilities, the reduced weight of the C-Lite cable range results in a typically 30 per cent faster reaving (cable pulling) time. This enables more cable to be installed for the same weight, resulting in faster installation times and reduced costs. The reduced diameter of the cables enables smaller bend radii to be used and more cables to be accommodated within the same space. Alternatively, smaller and lower-cost cable accessories can be used(smaller glands and cable trays, for example), meaning further weight and cost savings.
Using a reduced amount of combustible materials and offering low smoke generation, all C-Lite cables are constructed from flame retarded, halogen-free cores and Raychem brand Zerohal outer cable sheath. The components are designed for an operating temperature range from -40 to +120degC. C-Lite cables are approved by DNV, Lloyds Register, Germanischer Lloyds and ABS.
