Flexible conductor wiring within the confirmed board design.
Single-core PVC insulated building wire with a flexible stranded copper conductor for fixed wiring routes where easier bending and routing are required.

BVR uses multiple copper strands to provide greater installation flexibility than rigid-conductor building wire of the same nominal cross-sectional category. It is intended for fixed wiring applications where easier bending and routing assist installation.
Reference sizes with current technical data: 2.5–70 mm²
Additional commercial sizes can be reviewed against the required conductor construction and applicable product specification.
| Nominal section | Conductor construction |
|---|---|
| 2.5 mm² | 19 / 0.41 mm |
| 4 mm² | 19 / 0.52 mm |
| 6 mm² | 19 / 0.64 mm |
| 10 mm² | 49 / 0.52 mm |
| 16 mm² | 49 / 0.64 mm |
| 25 mm² | 98 / 0.58 mm |
| 35 mm² | 133 / 0.58 mm |
| 50 mm² | 133 / 0.68 mm |
| 70 mm² | 189 / 0.68 mm |

BVR is a Chinese product designation used for flexible PVC insulated building wire. Applicable Chinese construction is reviewed against JB/T 8734.2-2016. If the project specifies an IEC, EN, BS or other national designation, send the exact standard for technical review before supply is confirmed.
Flexible conductor wiring within the confirmed board design.
Internal fixed wiring where easier routing assists installation.
Interior fixed wiring routes requiring greater installation flexibility.
Protected routes where flexible conductor construction assists installation.
Cable selection, conductor size and installation method must follow the applicable local electrical code and project design.
Common electrical colours are confirmed against the order. Typical coil length is 100 m. Other export coil lengths, marking and packing can be reviewed according to confirmed order requirements.
Huanyu maintains current domestic manufacturing authorization and model-specific CCC documentation for selected building-wire products. Exact model scope is confirmed against the applicable certificate and order specification.
