电缆保护套管是电力工程中推广使用的一种新型套管材料。随着电力电缆埋地敷设工程的迅速发展，对电缆套管提出的更高要求，电缆保护套管是采用聚乙烯PE和钢管经过喷砂抛丸前处理、浸塑或涂装、加温固化工艺制作而成。它是保护电线和电缆常用的一种电绝缘管。保护电缆，用电，现在都开发新型的电缆保护套管了，也能更节约资源。

Cable protective conduit is a new type of conduit material widely used in power engineering. With the rapid development of buried power cable laying engineering, higher requirements are put forward for cable sleeves. Cable protective sleeves are made of polyethylene PE and high-quality steel pipes through sandblasting, shot blasting, impregnation or coating, and heating and curing processes. It is a commonly used electrical insulation tube for protecting wires and cables. Protecting cables and ensuring safe electricity use, new types of cable protective sleeves have been developed, which can also save resources more.

而电缆桥架也叫电缆槽盒（简称桥架），厂房或建筑物电缆比较多的，从配电间出来的电缆要放到电缆桥架里面，电缆桥架起到保护电缆的作用。电缆桥架是使电线、电缆、管缆铺设达到标准化、系列化、通用化的电缆铺设装置。

快盈V500大发And cable trays, also known as cable tray boxes (referred to as trays), are used in factories or buildings where there are more cables. The cables coming out of the distribution room should be placed inside the cable trays, which serve to protect the cables. Cable tray is a cable laying device that standardizes, serializes, and generalizes the laying of wires, cables, and conduit cables.

它的种类有槽式电缆桥架，一种全封闭型电缆桥架，它适用于敷设计算机电缆、通信电缆、热电偶电缆及其它高灵敏系统的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的效果。托盘式电缆桥架，它具有重量轻、载荷大、造型美观、结构简单、安装方便等优点，它既适合用于动力电缆的安装，也适用于控制电缆的敷设。梯级式电缆桥架，适用于一般直轻大电缆的敷设，特别适用于高、低动力电缆的敷设。那么电缆保护管和电缆桥架的作用、分类是什么？下面本文简单地给大家讲一讲，看完文章希望能给广大电气人员加深对电缆保护管和电缆桥架的了解。

Its types include slot type cable tray, a fully enclosed cable tray, which is suitable for laying computer cables, communication cables, thermocouple cables, and other highly sensitive control cables. It has good shielding interference and cable protection in heavily corrosive environments. Tray type cable tray has the advantages of light weight, large load capacity, beautiful appearance, simple structure, and convenient installation. It is suitable for both the installation of power cables and the laying of control cables. Cascade cable tray is suitable for laying general straight light large cables, especially for laying high and low power cables. So what are the functions and classifications of cable protection pipes and cable trays? Below, this article will briefly explain to you. After reading the article, I hope it can deepen the understanding of cable protection pipes and cable trays for electrical personnel.
