请问以线缆连接的灯具,对线缆承重的要求是什么?

请问以线缆悬挂的灯具,对线缆承重的要求是什么?

是吊灯还是仅仅外部接线?

相当于吊灯的,灯串。串在一起有100个灯。都是用导线连接的!

电线不小于0.75mm

引用第4楼LJX198325于2011-11-15 08:34发表的:
电线不小于0.75mm

这个是从额定电流上来考虑的。

请参考EN50598.1 CLS4.14.2.
首先线的承受总的质量不超过5千克,且线径每平方毫米上承受的力部超过15牛顿。

考虑有三点-------取线三个中线径最大的:
1)如果是灯串:
The nominal cross-sectional area of the conductors shall not be less than the following values:
a) 0,5 mm2 for class II lighting chains with E5 or E10 lampholders or other small lampholders;
b) 0,75 mm2 for class II lighting chains with E14, E27, B15 or B22 lampholders and fitted with
series connected lamps;
c) 1,5 mm2 for class II lighting chains with E14, E27, B15 or B22 lampholders and fitted with
parallel connected lamps;
d) 0,5 mm2 for class III chains and parts of chains supplied by SELV and with a maximum
rated wattage exceeding 50 W;
e) 0,4 mm2 for class III chains and parts of chains supplied by SELV and with a maximum
rated wattage not exceeding 50 W;
f) 1 mm2 for the cable between the plug and a sealed chain without joints;
g) 1,5 mm2 for the cable between the plug and a sealed chain with joints.

2)针对吊灯:
– 0,75 mm2 for ordinary luminaires;
– 1,0 mm2 for other luminaires.

3)考虑电流,可以百度一下 (考虑线径和电流之间的对应关系)
