Description
Features
1.1 Rated voltage: main control wire core 300/500V; wire pair unit 300/300V.
1.2 Operating temperature: the ambient temperature is 0~40°C; the maximum operating temperature of the conductor does not exceed 70°C.
1.3 The highest elevator speed: TVVB/WDZ-TYYB type does not exceed 1.6m/s; TVVBG/ WDZ-TYYBG type does not exceed 3.5m/s; THVVBG/WDZ-THYYBG type does not exceed 6.3m/s.
1.4 Suspension length: The free suspension length of the accompanying cable installation does not exceed 35m for TVVB/WDZ-TYYB type, 80m for TVVBG/WDZ-TVVBG type, and 150m for THVVBG/WDZ-THYYBG type.
1.5 Bending radius:
- The fixed laying part should not be less than 5 times the actual short diameter H (short side dimension) of the cable
; both sides shall be parallel).
1.6 Installation of cables:
If there is no tension element, the cable should be clamped and installed with a fixed clip. If there is a tension element, the tension element should be pulled out first and installed with a special sling.
1.7 Service life: 3 million times.
