VFF Flat Vinyl Power Cord for Heat-Resistant Wiring
Caution
Product Description
- Power cable VFF series '- Flat Vinyl Cord from TANAKA DENSEN.
- Vinyl flat cord made with PVC insulation for the excellent heat-resistant property. Effective in areas where heat-resistant property is required due to temperature increase of wiring inside electrical appliances.
- The overall length of power cable can be selected in 2 sizes, 100 m or 200 m.
- The insulation resistance at normal temperature (20°C) is 5 MΩ·km or more.
- The number core of power cable is 2 cores.
