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).

- Customized Elevator Cable
1. Make sure all the equipment inside the control panel cabinet is connected to earth properly. The short and thick earth wire should be connected to the suitable earth point or earth busbar. 2. The sheathed customized elevator cable usually uses flat conductor (such as metal mesh) which has low impedance under high frequency power transmission. 3. The power cable must be shielded in order to restrain the radiation and transmission of electromagnetic wave. At the same time, transfer impedance of the shield layer needs to be taken into consideration.
