There are many factors to consider when selecting cable glands for industrial installations. Neglecting to pay due attention to some of these factors may cause unnecessary anxiety at a future point in time when the equipment and cables have been delivered on site, but for example the cable glands have either been forgotten to be ordered or it is discovered that they are the incorrect type or size at the very point when they are needed the most. Good advice would be to allocate some value added planning and preparation time to the subject of cable gland selection so as to avoid the great inconvenience which is likely to occur at a critical point in time. In the event that a user or contractor is in possession of a cable schedule that requires a cable gland selection and sizing process to be carried out, CMP Products would be more than happy to assist in carrying out this process at no cost to the enquirer. Please contact CMP Products for further information on this subject.

Steel Wire Armoured (SWA) BS5467 Cable is a robust and hard-wearing power cable with copper conductors, XLPE insulation, steel wire armour and a black PVC sheath. It is designed for the supply of mains electricity – for power networks, underground systems and in cable ducting – and is suitable for both indoor and outdoor use.
With its steel wire armour, SWA Cable is particularly useful in external or underground projects. As well as providing effective mechanical protection, the armour enables it to withstand higher pulling loads.
SWA’s XLPE (Cross-Linked Polyethylene) insulation is resistant to a wide range of chemicals and has good thermal stability.
As I was nursing my baby, my cousin's six-year-old daughter, Krissy, came into theroom. Never having seen anyone breast- feed before, she was intrigued and full of all kinds of questions about what I was doing.
After mulling over my answers, she remarked, "My mom has some of those, but I don't think she knows how to use them."
在国外长输管道施工中由于经常和业主、监理等打交道,施工中用到的程序文件和施工规范等很多都是英语版本,业务交流、各种形式的会议等都会用到英语,而管道施工中用到的一些词汇往往与通用的英语词汇意思差别很大,有些是专业术语,有些是行话,确实很难理解,造成误解和笑话,笔者根据多次国外施工中的经验和平时的收集积累,选出一些特色词汇进行探讨。 为了便于理解,笔者主要按照管道施工程序展开本文探讨部分常用的词汇。pipe alignment(setting out)是“放线之意”,即确定沿线路方向的管道实地安装的中心线位置,并划定管道施工界限的过程。field hand over stake不可按字面翻成在田野里移交树桩、应该是“现场交桩”之意,设计部门将所设计的管道控制桩、测量成果表及水准点资料在现场移交给施工单位。right-of-way意思是为管道施工临时征用的带状土地,其基本意思是路权,因为只有在得到土地所有者的书面授权下才能在该路段施工。 …… ============================== 点击此处阅读全文
