Spectra-Strip Low Smoke / Halogen Free Twist 'N' Flat� cable combines the time and cost savings of mass
termination with the added benefits of halogen free, highly flame
retardant cable... ideal for use in closed environments where ventilation is poor, such as subways, elevators, and
ships. It is designed to reduce the generation of toxic and corrosive gases that are emitted from typical PVC
insulated cables during combustion. These gases can injure personnel enclosed within these confined spaces and can
also corrode delicate components within electronic equipment. Many well-documented cases exist of extensive injury
and death occurring as a result of fires involving these PVC generated toxic gasses, e.g., the London Subway fire,
the Beverly Hills Supperclub fire, the Dusseldorf Airport fire, and the HMS Sheffield sinking.

This cable is well suited to equipment such as communications and computing devices, within closed environments,
or wherever the crosstalk performance of twisted pairs is needed. Labor savings of up to 95% as compared to
automatic strip and crimp termination are readily achieved.
Twist 'N' Flat� cable consists of stranded round conductors insulated with color coded polyolefin, twisted into
pairs and laminated between layers of polyolefin film to form a planar cable. The twist in adjacent pairs is
reversed to reduce cable crosstalk even further. Standard cables alternate 18-inch (45,7cm) long twisted pair
sections with 2 inch (5,1cm) flat sections in which the conductors are laminated in parallel.
Twist 'N' Flat� cable can also be fabricated to your custom requirements. Flat sections can be made longer
to allow room for multiple connectors. Twisted pair length can be varied from a minimum of 6 inches to many
feet to conform to your requirements. The lamination can be fabricated "loose" at specified points
to provide easy access to individual conductors. For complete details, consult the Spectra-Strip sales office
