西門子低壓母線系統是替代 電纜配電的經濟、理想型方案
可選擇一級耐火型/XL/LR/LD/BD/
As a substitute for the cable distribution system, Siemens low-voltage busbar
is the economic, ideal solution!
安裝電纜時，新負載線路只能按照傳統方法連接分支配電屏，
費用高且安裝復雜。
When install cables, the new load lines only in accordance
with traditional connection methods to connect branch
distribution board, costly and complicated to install
母線槽的插接單元接近負載設備，現場布局更清晰、靈活，
經濟實用。
The tap-off units of busbar system are close to the loading
equipments, enjoying clearer site layout, flexible, economical
ａnd practical features.
電纜布線復雜，火災荷載高
Cable layout is complex, high fire load
母線設計簡單清晰，火災荷載低
Busbar planning is easy, low fire load
西門子低壓母線系統
Siemens low voltage trunking system
母線槽系統主要作為變壓器與配電柜之間的輸電設備以及配
電柜與負載之間的配電設備而被廣泛使用，與電纜相比，母
線槽系統不但安全，而且壽命長、性能可靠、使用方便。
西門子低壓母線槽產品主要有以下幾種類型 ：
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系統 額定電流400A~6300A用于變壓器低壓側到總低壓柜
LR系統 額定電流630A~6300A
LD系統 額定電流1000A~5000A
BD1系統 額定電流140A~700A 用于樓層干線系統
西門子母線槽系統電流覆蓋面廣，產品種類齊全，能滿足不
同用戶和工程項目的需求。所有母線槽系統均執行
標準，并通過了國內外機構的各項檢測與認證，如德國
波恩實驗室認證、英國ASTA、等，這樣就為產品的性
能提供了保證。
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.
