Vinyl flat cord for extension cord
OT-VFF/N-VFF/ARK-VFF
Vinyl flat cord for extension cord
【feature】
●It has a special structure that takes into consideration the harsh use of extension cords (bending, twisting, external pressure, etc.).
●The K-VFF insulator uses *spark resistant PVC.

■Spark resistance（AR）
VFF 2×0.75e has a spark strength more than 100 times higher than general VFF when a spark-resistant insulator is applied.
Evaluation method
Forcibly half-broken samples according to the bending test specified in JIS C 3005 are connected to the circuit shown in the left figure (load 700W), sparks (chattering) are generated at the half-broken points, bending the sample 30 times in 1 minute, and the number of times until breakage is evaluated.
