母線（母線槽）是由銅、鋁母線柱構成的一種封閉的金屬裝置，用來為分散系統(tǒng)各個元件分配較大功率。在戶內(nèi)低壓的電力輸送干線工程項目中已越來越多地代替了電線電纜，普遍應用在：高層建筑的層間供電、廠房的平面配電、低壓柜之間的聯(lián)絡、變壓器連接端的進線系統(tǒng)。下面濟南電纜橋架廠家來進行母線PK電纜的優(yōu)勢總結。

A busbar (busbar duct) is a closed metal device composed of copper and aluminum busbar columns, used to distribute large power to various components of a distributed system. In indoor low-voltage power transmission trunk projects, wires and cables have increasingly been replaced, and are widely used in inter story power supply in high-rise buildings, plane power distribution in factories, interconnection between low-voltage cabinets, and incoming line systems at transformer connections. Next, the manufacturer of cable tray in Jinan will summarize the advantages of bus PK cable.

載流能力

Current carrying capacity

母線--大：250A～5000A

Bus - large: 250A~5000A

電纜--小：單根四芯電纜一般大580A

Cable - Small: A single four core cable is generally 580A larger

系統(tǒng)結構

System structure

母線--簡潔清爽：線性設計、結構簡單

Busbar - simple and refreshing: linear design, simple structure

電纜--錯綜復雜：回路較多，布線復雜

Cable - intricate: multiple loops and complex wiring

占用空間

Occupy space

母線--小：結構緊湊

Busbar - small: compact structure

電纜--大：約為母線槽的3-4倍

Cable - Large: Approximately 3-4 times the size of the bus duct

散熱性能

Heat dissipation performance

母線--高：母線為密集型結構，外殼采用高導熱性能的鋁合金型材，散熱方式為整體式熱傳導，熱傳導效率高，散熱性能好。

Busbar - High: The busbar is of a dense structure, and the outer shell is made of aluminum alloy profiles with high thermal conductivity. The heat dissipation method is integrated heat conduction, with high heat conduction efficiency and good heat dissipation performance.

低：電纜的芯線絕緣和外皮絕緣材料散熱性能差，在橋架內(nèi)多層敷設時，散熱性能更差。

Low: The core insulation and outer insulation materials of the cable have poor heat dissipation performance, and when laid in multiple layers within the bridge, the heat dissipation performance is even worse.

絕緣性能

Insulation performance

母線--高：130/180℃

Bus - height: 130/180 ℃

電纜--低：95/105℃

Cable - Low: 95/105 ℃

性能

Safety performance

母線--高：回路少、故障點少

Bus - high: fewer circuits and fewer fault points

電纜--低：單獨敷設電纜，回路多，故障點多

Cable - low: laying cables separately, with multiple loops and multiple fault points

安裝強度

Installation strength

母線--小：單節(jié)長度一般大不超過3米，安裝省時、方便，安裝成本低。

Busbar - small: The length of a single section generally does not exceed 3 meters, which is time-saving, convenient, and low in installation cost.

電纜--大：技術難度大、施工周期長、人為因素多、隱患點多。線路越長，施工難度越大。

Cable - Large: High technical difficulty, long construction cycle, multiple human factors, and multiple hidden dangers. The longer the route, the greater the difficulty of construction.

操作性能

Operational performance

母線--方便：可在就近位置的插接箱內(nèi)操作

Bus - convenient: can be operated in the nearby plug-in box

電纜--煩瑣：配電室的開關柜內(nèi)操作

Cable - tedious: operation inside the switchgear in the distribution room

系統(tǒng)配置

system configuration

母線--簡單：母線單元通用性、互換性強，所有零部件可以拆卸后重新組裝使用；系統(tǒng)擴展既可以增加母線長度也可以增加分接單元（插接箱）。

Bus - Simple: The bus unit has strong universality and interchangeability, and all components can be disassembled and reassembled for use; System expansion can increase both the length of the bus and the number of tapping units (plug-in boxes).

電纜--復雜：系統(tǒng)擴展必須增加回路，電纜必須重新由配電室引設備。

Cable - Complex: System expansion requires adding loops, and cables must be re led from the distribution room to the equipment.
