Question:
rental housing to install wiring, I have bought the main line is the square of the four single-core BVV line, but I installed the person asked me to switch to four square Multi-core cable, single core wire, he said, difficult to install, at the corner corner pull them.

but I think single core and multi-core are the same size cross-section, I will certainly incumbent, cable? Or the pull of electrical qualifications not enough, because he said if it is single-core do not come to me to install, how do I do?

is the deliberate installation of electrical trouble, or how I like? I compromise him???

we all know to the point.
Thank you

Answer:
In fact, using multiple cores a little better for you. because the single-core line in the corner, easy to fold injury, or be broken, while the multi-core line, since it than the Single line of soft, so it is not afraid of being folded, and from the installation point of view, multi-core cable is better than the single-core cable wiring then some. But you is to take the open wire, that single core multi-core I think it would not matter. If the , that really do not give you an electrician, and you can not find another electrician, I advise you, or to compromise it, Single line and multi-core cable prices are the same, you is unspeakable for multiple cores.

Answer :
4 square is in fact a multi-core cable sheathing line, BV-line than the single core for more than a protective layer, is only suitable for laying out, if the threading in the pipe with single core BV cable. Ming deposition can be multi-core cable sheathing line.

-line slot with the single-core BV line can be laid because the groove is a protective layer, and then multi-core cable sheathing line is not necessary, and multi-core cable sheathing line unit also high.

Answer:
“Single line of hard to install, he said,” is not installed, there is no reason you should not compromise. The electrician does not give you to install you can find another electrician.
for the same cross-section of the wire, multi-core cable more expensive than the price of single-core line. The so-called multi-core lines to use Another reason is easy to break and no reason, because you installed after the line is unlikely to go off every day, wire bar?

Answer:
relatively soft multi-strand wire, if you install from time to time by right-angle turn, then, it was suggested to use multi-strand wire. single-strand wire insulation in the right-angle turns easily be torn.

Chinese:单芯电线是不是太难拉?要改用多芯的电线??

类别: 电力

问题:
出租房安装电线,我目前买的主线是用4平方的单芯BVV线,但给我安装的人要求我改用4平方的多芯线,他说单芯线难安装,在转弯角处拉不动.

但我觉得单芯与多芯都是一样大小的截面,我一定要换电线吗? 还是这个拉线的电工资格不够,因为他说如果是单芯的就不给我安装,我怎么办?

是这个安装电工故意麻烦我还是怎么样? 我是否妥协他???

大家知道的给点意见.
谢谢

回答:
其实,用多芯的对你要好一点.因为,单芯的线在转角处,容易被折伤,或者被折断,而多芯线,由于它要比单芯线软,所以它不怕被折,而且从安装的角度来讲,多芯线比单芯线接线要好接一些.不过,你是走明线,那单芯多芯我认为就无所谓了.如果,那个电工实在不给你安,你又找不到别的电工,我劝你还是妥协吧,单芯线与多芯线价格是一样的,你可以拿去换多芯的.

回答:
4平方的多芯线实际就是护套线，比单芯BV线还多一保护层，只适合明敷设，如果在管内穿线用单芯BV线即可.明敷可用多芯线护套线。

在线槽内敷设用单芯BV线即可，因为线槽就是保护层，再用多芯线护套线没有必要，并且多芯线护套线单价也高。

回答:
"他说单芯线难安装"就不安装,没有道理,你不应妥协.这个电工不给你安装你可以找别的电工.
对于相同截面的电线,多芯线要比单芯线价格贵一些.而所谓要用多芯线的另一理由是容易折断也没有道理,因为你的线路安装好后,不大可能天天去折电线吧?

回答:
多股线比较柔软,如果你按装时有直角转弯的话,建议还是用多股线.单股线在直角转弯处绝缘层容易被弄破.
