PVC Conduit Wire
As the actual manufacturer of these cables, not simply a distributor, Tratos has total control of the design, quality and manufacturing process from the purchase of the raw materials through to final testing and despatch to our customers. Having control of the manufacturing process Tratos have developed this cable to have the optimum balance of properties, toughness to withstand pulling into conduit and trunking combined with a smooth, low coefficient of friction, surface to ease installation and prevent jamming.
Now officially identified by the designations H07-U and H07-R, these cables are also known by their old CMA Code 6491X. Cables designated “-U” have class 1 conductors, “-R” have class 2 conductors” flexible class 5 conductors designated “-K” are available on request. Tratos manufacture a complete range of cables for building and construction applications that are both safe and reliable when correctly selected, installed and properly used.

ApplicationSuitable for power and lighting circuits and building wiring. Installed in surface mounted or embedded conduits, cable trunking or similar closed systems and for fixed protected installation in or on lighting fittings and inside appliances, switchgear and control gear. In particular for installation where fire, smoke emission and toxic fumes create a potential threat.

The tension applied to a cable should not exceed the values of tensile stress per conductor given below. This is subject to a total maximum tensile force of 1000 N.
- 50 N/mm2 during installation;
- 15 N/mm2 for static tensile stress.
Minimum bending radius:
- ≤8 mm 4D
- >8 mm ≤12 mm 5D
- >12 mm 6D
