电缆桥架与母线槽的比较
电缆桥架通俗地讲就是个承载量大，容易安装，便于拆解，便于维护，环境适应性强的线缆敷设槽及托盘。可明装也可暗装。电缆桥架一般选用优质冷轧、热轧板材、带钢、不锈钢、玻璃钢、PVC、铝合金等材质。表面处理有喷漆、电镀锌、热浸锌、喷塑等。 电缆桥架按类型分为:槽式桥架、托盘式桥架、梯级式桥架、组合式桥架，大跨距桥架，新型免螺栓桥架等。
Cable tray informally is a big load, easy to install, easy to disassemble, easy to maintain, environment adaptable laying cable trough and tray. Will be, with dark suits. Cable tray generally selected high-quality cold-rolled, hot-rolled plates, strip steel, stainless steel, glass reinforced plastics, PVC, aluminum alloy material, etc. Surface treatment has spray paint, electric galvanized, hot-dip zinc, coating, etc. Cable tray by type can be divided into: groove bridge cascade type, tray type bridge, bridge and composite bridge, big span bridge, the new free bolt bridge, etc.
槽式桥架是一种全封闭型桥架，它适用于敷设计算机电缆、信电缆、热电偶电缆及其它高灵敏系统的控制电缆等。槽式桥架对控制电缆的屏蔽干扰和重腐蚀环境中电缆的防护都有较好效果。 也是目前使用最多的桥架。
Groove bridge is a full closing bridge, it is suitable for laying computer cables, cables, thermocouple cables and other high sensitive system control cable, etc. Groove bridge of control cable shield cable interference and heavy corrosion environment protection has a good effect. Is currently the most used bridge.
托盘式桥架是石油、化工、轻工、电视、电讯等方面应用较广泛的一种。它具有重量轻、载荷大、造型美观、结构简单、安装方便等优点。它既适用于动力电缆的安装，也适用于控制电缆的敷设。
Tray type bridge is petroleum, chemical industry, light industry, TV, telecom etc. Application of one of the more widely. It has light weight, large load, beautiful shape, simple structure, easy installation, etc. It applies to the installation of power cable, can also be applied to control the laying of the cable.
梯级式桥架具有重量轻、成本低、安装方便、易散热、通风性好等优点。它适用于一般直径较大电缆的敷设，特别适用于高、低压动力电缆的敷设。
This type bridge has light weight, low cost, easy installation, easy to heat dissipation, good ventilation, etc. It is suitable for general larger diameter cable laying, especially suitable for high and low voltage power cable laying.
新型无螺栓桥架是一种轻型化，模块化，简易化，节能的新产品，是省时省料的新技术产品，是桥架更新换代产品。
New type bolt bridge is a kind of light-duty, modular, facilitation, energy-saving new products, saving time and material for is new technology products, is a bridge updated products.
Large span bridge slotted type, step type tray. Mainly suitable for indoor and outdoor use place with large span. Features: large load, large span, high strength, light structure, simple and easy for construction. Large span cable bridge is the bridge of the third generation product.
母线槽通俗地讲就是个承载量大，容易安装，便于拆解，便于维护，环境适应性强的大电缆。优势明显，也有其不可避免的缺陷，触面易被腐蚀。但母线槽在北方不存在这些问题，因为湿度很小。
Bus duct informally is a big load, easy to install, easy to disassemble, easy to maintain, environment adaptable large cable. Obvious advantages, also has its inevitable flaws, contact surface is easy to corrode. But the bus duct does not exist in the north of these problems, because the humidity is very small.
母线槽将电气装置中各截流分支回路连接接在一起的导体。它是汇集和分配电力的载体，又称汇流母线槽。 习惯上把各个配电单元中载流分支回路的导体均泛称为母线槽。母线槽的作用是汇集、分配和传送电能。母线槽在运行中，有巨大的电能通过，短路时，承受着很大的发热和电动力效应，必须合理的选用母线槽材料、截面形状和截面积以符合安全经济运行的要求。
Bus duct connect each intercepting branch circuit in electrical devices connect together of the conductor. It is the carrier of collection and distribution of electricity, also known as the bus bus duct. Traditionally the current-carrying branch circuit conductor in the power distribution unit are loosely called bus duct. The role of the bus duct is the collection, distribution and transmit power. Bus duct in operation, there is a huge energy through, short circuit, under a lot of heat and electricity power effect, must bus duct reasonable selection of materials, cross section shape and cross-sectional area in accordance with the requirements of the safe and economic operation.
母线槽的常用类型，有硬母线槽、软母线槽两种。硬母线槽用铜或铝做成，形状有矩形、槽形和管形数种，多用于35 kV及以下的屋内配电装置，110 kv～220 kv屋外配电装置有时也采用铝管母线槽。地区母线槽常用的软母线槽有铝绞线、铜绞线或钢芯铜线线等，软母线槽多用于35 kv以上的屋外配电装置。
Common types of bus duct, which has two kinds of hard bus duct, soft bus duct. Hard bus duct with copper or aluminum, has a rectangular shape, trough and tubular several, more used to the room of 35 kV and below power distribution equipment, 110 kV and 110 kV outdoor distribution equipment sometimes using aluminum tube bus duct. Regional bus duct commonly used soft bus duct has aluminum stranded wire, copper wire or steel core copper wire, etc., soft used at 35 kv bus duct distribution equipment outside.
