西门子低压母线系统是替代 电缆配电的经济、理想型方案
可选择一级耐火型/XL/LR/LD/BD/
As a substitute for the cable distribution system, Siemens low-voltage busbar
is the economic, ideal solution!
安装电缆时，新负载线路只能按照传统方法连接分支配电屏，
费用高且安装复杂。
When install cables, the new load lines only in accordance
with traditional connection methods to connect branch
distribution board, costly and complicated to install
母线槽的插接单元接近负载设备，现场布局更清晰、灵活，
经济实用。
The tap-off units of busbar system are close to the loading
equipments, enjoying clearer site layout, flexible, economical
ａnd practical features.
电缆布线复杂，火灾荷载高
Cable layout is complex, high fire load
母线设计简单清晰，火灾荷载低
Busbar planning is easy, low fire load
西门子低压母线系统
Siemens low voltage trunking system
母线槽系统主要作为变压器与配电柜之间的输电设备以及配
电柜与负载之间的配电设备而被广泛使用，与电缆相比，母
线槽系统不但安全，而且寿命长、性能可靠、使用方便。
西门子低压母线槽产品主要有以下几种类型 ：
As the power distribution equipment between transformer
ａnd switchgear, between switchgear and loading
equipments, busbar trunking system is widely applyed. Such
system is more safe, long life-span, reliable and convenient to
operate over cable installation.
Siemens Busbar Trunking Systems mainly offers the busbar
trunking systems as the following types:
XL-II系统 额定电流400A~6300A用于变压器低压侧到总低压柜
LR系统 额定电流630A~6300A
LD系统 额定电流1000A~5000A
BD1系统 额定电流140A~700A 用于楼层干线系统
西门子母线槽系统电流覆盖面广，产品种类齐全，能满足不
同用户和工程项目的需求。所有母线槽系统均执行
标准，并通过了国内外机构的各项检测与认证，如德国
波恩实验室认证、英国ASTA、CCC认证等，这样就为产品的性
能提供了保证。
Siemens busbar trunking system cover wide current range,
varied products can meet the needs of different users and the
demａnd for projects. All the busbar systems are type-tested
low-voltage assembly (TTA) in accordance with international
advanced standard IEC/EN, passed a series of international
ａnd domestic tests and certificates, such as Germany Bonn
Electric Laboratory Test, ASTA from UK, CCC, etc. which
guarantee our products performance.
