Industry standard triax cable to a BBC specification, produced with flame-retardant polyurethane jackets, well suited to the onerous conditions normally associated with studio floor and OB situations. Available with red and black outer sheaths. A termination service is available for these cables, and the appropriate Fischer and Lemo connectors are stocked. Readymade cables using both standard and flexible Triax are available - see Canford triax camera cables.
A PVC jacketed version is also available; this has the same construction apart from the outer jacket which is PVC instead of PUR.
