Product introduction产品简介

Usage: this product is suitable for the fixed laying of power devices with rated AC voltage of 450/750V and below. Such as home improvement lighting. Fixed wiring can be used for indoor laying, pipe threading and other occasions. Because BVR is soft-structured, its application scope is mostly in soft environment. The difference between BVR wire and BV wire is that the conductor diameter of R-type wire is soft copper wire. That is, increase the number of conductors and reduce the diameter of a single conductor, and the diameter of a single conductor is less than 1 mm. In this way, the BVR wire is very soft, the laying angle requirement is greatly reduced compared with BVR wire, and it is more convenient and fast to thread the conduit slot, which reduces the working intensity and greatly improves the working efficiency. By the majority of electricians and building decoration personnel like it!
用途：本产品适用于交流额定电压450/750V及以下的动力装置的固定敷设。如家装照明。固定布线可用于室内敷设、穿管等场合。由于BVR是软结构的，运用范围也多在软环境下。BVR电线和BV电线的区别在于，R型电线导体线径为软铜丝。即：增加导体根数，减少单根导体直径，单根导体直径小于1mm。这样一来，BVR电线十分的柔软，敷设角度要求较BV电线大大降低，穿线管线槽时更加方便，快捷，降低工作强度的同时大大提高了工作效率。深受广大电工及建筑装饰人员喜欢！
