Mechanical Specification of 60227IEC71f (TVVB) Flexible Elevator Cable:
Free suspension length: ≤35m;
Travel height: ≤70m;
Rated speed : ≤1.6m/s;
Freed bending diameter: ≤400mm;
Minimum diameter: 30mm;
Flexibility test: >30000 times (No broken circuit or short circuit occurs to the insulation core.)
Lead Free Environmental Performance: Heavy metal content in our product fully complies with the requirement of EU RoHS.
Note: In practical operation, when the operating speed is in the range of 1.6m/s-4.0m/s and free suspension length is over 35mm, reinforced component made of galvanized soft steel wire or fiber wire need to be added to the lead-free elevator cable. The corresponding cable model is 227IEC 71f (TVVB) (G).
