Development of flame retardant, low aggressivity cables

The construction of a fire retardant, low aggressivity cable may, depending upon the severity of application, require four components based on polymer insulation, fire barrier tape, bedding and sheath. A number of high performance polymers have been evaluated as insulation materials, whilst STC have developed a range of bedding and sheathing materials, both thermoplastic and crosslinkable, to meet the exacting requirements of industrial and military users.
