TRVVB, TVVB and TVVBG elevator travelling-cable enquiries include flame resistance, a three-core 2.5mm² layout and flat construction with steel wire. The detailed description specifies stranded copper conductors and PVC insulation at 300/500 V, with a −40 to 105°C working range.
Agree the flat or round geometry and steel-wire arrangement
The featured request is flat, while the shape field states round. Resolve the finished geometry for the selected cable and identify the steel-wire position, material role and support arrangement. Actual TVVB/TVVBG labels include three-core sizes of 0.75, 1, 1.5, 2.5 or 4mm. Confirm the intended size units and exact family/code against the featured 3×2.5mm² requirement.
- Copper is the stated conductor material.
- The conductor construction is stranded.
- PVC insulation is described.
- The voltage designation is 300/500 V.
- The stated working range is −40 to 105°C.
Define the selected flame and travelling-duty requirements
Broader size references include 0.75, 1, 1.5, 2.5, 4, 6, 10, 16 or 25 with mm wording. Establish conductor area/units, strands, completed layers and terminal mapping. For elevator, automatic telescopic-door or lift use, give actual load, travel, hanging conditions, bend radius, speed and exposure. Identify the relevant flame-test and selected-construction evidence for the stated flame-resistance requirement.
Evaluate a sample against the actual installation drawing
Free samples are offered. Request applicable CE, RoHS, ISO9001 or CCC scope for the chosen version. Include the reviewed three-core geometry and steel-wire drawing, finished lengths and quantity. Retain the 1 m offering with the selected sample specification so the proposed build can be checked against its support and motion conditions.
