Identification and length marking: there is a sexual identification mark on the cable appearance, and the marking interval is not more than 1m.
TRVV flexible control cable product features: according to customer requirements can be customized color core or loo core. High quality PVC mix is adopted to reduce the requirement of cable outer diameter for installation space. The designed cycle bending life is 5 million times, and the actual use has exceeded 6 million times.
BVR相比BV线来说要软、过流能力强、施工更方便，价格也要贵一些。
由于BV线是单股线和同截面积BVR相比，它的铜丝要粗，当温度长期较高时不容易烧断；BVR线的铜丝比较细，温度较高时容易烧断其中一两根。
只要电线中有一两根铜丝被烧断，那么烧断截面积减少，电阻更大，电线更容易被烧毁。
在实际应用中，由于BVR线比较软，时间一长接头容易松动；而BV线相对来说就好很多，在家装中为了防止接头松动都要采取“挂锡”工艺。
