|Nominal outer diameter -Tolerance +/- 0,5 mm|
|FF – Extra-flexible conductors in plain or tinned annealed copper|
R – Insulation with TI1 PVC
07 – Lay-up in concentric layers separated by a textile tape
Y – Galvanized steel ropes
R – Outer sheath inTM2 PVC
|Cores identification according to CEI-UNEL 00722 tables; usually with progressive numbering, with or without green-yellow conductor: Blue outer sheath.|
On request and for minimun quantitative or 3-4000 m, possibility of supplying with black outer sheath.
|Tabella UNEL 35010 sigle di designazione|
CCEI 20-29/IEC 228 conductors for insulated cables
CEI 20-20/IEC 227 PVC insulated cable
CEI 20-35/IEC 332.1 Flame retardant
|The tensile stress in this control cable is supported by 2 side ropes inserted in th eouter sheath. Th esteel ropes have a tensile strengh of 2100 N: The cable is used in pendant push-button panels, yard machines, handling and lifting systems.|
In order to improve flexibility, the inner conductor bundle is wrapped in a textile tape which improves the capability of reciprocal motion between conductors and outer sheath.
